Frequently asked questions


Is GYNALAC safe?

GYNALAC is tried and clinically tested. The active ingredients in the product occur normally in a healthy vagina and have been used to restore vaginal imbalance since the early 1990s.

Who should not use GYNALAC?

Do not use GYNALAC if you are allergic to any of its ingredients. GYNALAC can be used during breastfeeding and during pregnancy, however, you should consult your doctor if you have any of the symptoms of a vaginal infection during pregnancy. Do not use GYNALAC if you are trying to conceive as the gel has a low pH, which makes the environment less suitable for sperm. Please note, GYNALAC should not be used as a form of contraception.

Does GYNALAC have any unwanted effects?

In rare cases, vaginal itching or burning may occur at the start of treatment. This reaction has also been observed with other vaginal preparations and usually goes away. If you have any concerns you should consult your healthcare professional.

What should I do if I think I’m having a reaction to the product?

If you have an allergy or reaction to any of its ingredients, the product should be discontinued. For more detailed information, please see the Warnings in the Product Information Brochure or on the packaging.

Can I use GYNALAC after being prescribed an antibiotic for Bacterial Vaginosis?

Yes, you can use GYNALAC immediately following an antibiotic treatment. Typical antibiotic treatments (metronidazole or clindamycin) for Bacterial Vaginosis infections can strip away beneficial bacteria, leaving conditions ripe for a new infection to begin, which means your latest bacterial infection might not be your last.

Using GYNALAC, immediately after completing a course of antibiotics can help put an end to these recurrences. GYNALAC helps restore the healthy vaginal flora required to aid in prevention of future infections.


How does GYNALAC different from a regular douche?

GYNALAC is a vaginal freshening gel – not a douche! Douching involves completely washing your vagina with a liquid, many of which contain harsh chemicals (like paraben preservatives). Douching disrupts the vaginal ecosystem – washing out the good bacteria as well as the bad bacteria, and can increase the rates of vaginal infections, like bacterial vaginosis and yeast infections. GYNALAC is a gel that is inserted the vagina. It has the same pH as a healthy vagina and supports the vagina’s self-cleaning mechanisms. It is paraben-free and is isotonic, which means that the salt concentration of the gel is the same as healthy vaginal tissue. Unlike many douches and freshening gels that are hypertonic, GYNALAC will not dehydrate vaginal cells. Instead, GYNALAC keeps vaginal cells properly hydrated.

Is it possible to prevent recurrences of Bacterial Vaginosis with GYNALAC?

Maintaining a balanced vaginal ecosystem is essential in preventing recurring infections. You can use GYNALAC even if you do not have a current infection, to maintain a healthy balance. We recommend you apply one dose (3 mL) of GYNALAC daily for 3 consecutive days at the end of your menstrual cycle.

Other tips to help prevent recurrence include:

  • Maintain a healthy lifestyle with regular exercise and a balanced diet.
  • If your doctor prescribes antibiotics, even for an unrelated condition, use GYNALAC, immediately after completing your course of antibiotics to help maintain a natural and healthy vaginal balance.
  • Keep genital area clean and dry.
  • Avoid using perfumed intimate products (soaps, vaginal deodorants, etc.) as these can disrupt the natural and healthy vaginal balance.
  • Avoid excessive washing (or douching) of the vagina, as this may strip away the healthy bacteria lining the vagina that prevent the unfriendly bacteria from over growing.
I suffer from odor, abnormal discharge, and discomfort after my menstrual cycle. Can GYNALAC help to prevent this?

If you notice a recurrence of symptoms around the time of your period, using GYNALAC immediately after your period can help to maintain the natural pH and prevent the symptoms from recurring.

If you use the product during your period, there is a risk that your flow could wash some of the product out, making it less effective. We recommend you apply one dose (3 mL) of GYNALAC daily for 3 consecutive days at the end of your menstrual cycle.

I have been diagnosed with a Yeast Infection. Can GYNALAC help?

If you have been diagnosed with a Yeast infection, you will need an antifungal treatment, as GYNALAC alone will not get rid of the candida (yeast) causing your Yeast infection.

GYNALAC is a natural pH regulator and can be used as an adjunct therapy to your antifungal treatment, to help restore your normal vaginal flora and relieve symptoms of itchiness, burning and dryness.

Do I need a prescription for GYNALAC?

GYNALAC is available without a prescription in most pharmacies across Canada. Ask your local Pharmacist today. You can also order GYNALAC online, visit the “Where to Buy” page on our website.

What happens if I miss a day of GYNALAC treatment?

We strongly recommend you apply one dose (3 mL) of GYNALAC daily for 7 consecutive days. If you miss a day, there is no need to start over. Simply, resume the regimen where you left off. However, if you miss several days, you may find you may need to repeat the entire treatment.

Should I wear a panty liner when using GYNALAC?

GYNALAC is formulated to be rapidly absorbed by your vaginal tissue. In the event of leakage, a panty liner may be used.

When is the best time to use GYNALAC?

It is best to use GYNALAC at bedtime.

Can I swim or have a bath after using GYNALAC?

Do not use GYNALAC before swimming or bathing. If you use the product before you swim or take a bath there is a risk that the water could wash some of the product out, making it less effective.

Can I have sex while using GYNALAC?

Yes, you can have intercourse while using GYNALAC. Please note, GYNALAC should not be used as a form of contraception.

Can GYNALAC be used with condoms?

Yes. GYNALAC can be used with condoms and other barrier contraceptives made with latex and polyisoprene, but not with polyurethane.

I am trying to get pregnant, can I still use GYNALAC?

Do not use GYNALAC if you are trying to conceive as the gel has a low pH, which makes the environment less suitable for sperm.

Can I still use GYNALAC if I’m pregnant?

Yes, GYNALAC is safe to use during pregnancy. However, if you have any of the symptoms of a vaginal infection during pregnancy you should consult your doctor.

Can I use GYNALAC if I’m breastfeeding?

Yes, GYNALAC is safe to use when breastfeeding.

What happens if GYNALAC is accidentally ingested?

GYNALAC is nontoxic. If ingested, there is no cause for alarm.

How should I store GYNALAC?

Store GYNALAC, in its box, in a dry place at room temperature, 15°C to 30°C. Do not use beyond the expiry date. The expiry date is stated on the tube and carton. Once used, the tube can be disposed of in accordance with local and environmental regulations.

How quickly does GYNALAC work?

Many women notice their symptoms start to improve after just one dose.

How long do I need to use GYNALAC for?

To effectively treat BV and relieve embarrassing fishy odour and abnormal discharge and discomfort associated with BV you should use 3 mL of GYNALAC vaginal gel per day, ideally at bed time for 7 days.

To maintain your natural pH balance and prevent recurrence of symptoms you can use 1-2 applications of 3 mL per week.

If you’re taking antibiotics GYNALAC can help to maintain your natural pH level if you administer a single application (3 mL) daily for 3 days after the end of antibiotic therapy.

If you notice you get BV around the time of your period, administer a single application (3 mL) per day for 3 days immediately after the menstrual cycle, for a minimum of 6 months.

How long is GYNALAC safe to use for?

It is not harmful to continue to use GYNALAC for longer than 7 days, however if symptoms do persist it is advisable to see your doctor.

Can I use GYNALAC in combination with antibiotics?

Yes. In fact, using GYNALAC for four to five days at the end of a course of antibiotics can help to restore the correct vaginal pH and prevent the growth of organisms that may cause an infection.

Is it normal to experience burning when using GYNALAC?

You may feel a temporary burning sensation when using GYNALAC, as you may have small abrasions in the vaginal tissue, which is common when suffering from a vaginal infection. However, this should go away quickly, if the burning is persistent, you should consult your doctor.

What is a vaginal pH?

Great question! Vaginal pH is a measure of how acidic or alkaline the vagina is. A healthy vaginal pH is usually between 3.8 and 4.5. This is important to know because an overly acidic or alkaline vaginal pH can lead to infections like yeast or BV, odor, excessive discharge, vaginal dryness, itchiness, vulva soreness and general discomfort.

Here are some things that may negatively impact your vaginal pH:

Antibiotics: Antibiotics kill off both the good and bad bacteria in the vagina. The problem is, the vagina needs good bacteria to fight off the infection causing bad bacteria. Without good bacteria, women are more likely to breed infections like yeast.

Sex: The alkaline pH value of semen is HIGH (usually around 7.1-8). Semen can disturb the vagina’s acidic environment, which can lead to BV.

Menstruation: Blood has a pH of 7.4, so during your period, vaginal pH can become elevated and cause discomfort and infection.

Menopause: A decrease in estrogen levels reduces the numbers of healthy bacteria in the vagina, and eventually can increase the vagina’s pH levels causing recurring infections.

FAQ about Bacterial Vaginosis

What are vaginal infections?

Vaginitis (or vaginal infections) is a medical term used to describe various conditions that cause infection or inflammation of the vagina that can result in discharge, itching and pain. The most common types of vaginitis are Yeast infections and Bacterial Vaginosis. Approximately 50% of all vaginal infections are classified as bacterial vaginosis, while only about 25% are classified as Yeast infections. If these kinds of infections are left untreated, they can lead to serious complications.

What Is Bacterial Vaginosis?

Bacterial vaginosis is an imbalance in the bacteria normally found within the vagina so that levels of beneficial, lactic-acid producing probiotic bacteria (Lactobacilli) are reduced or absent, and there is an overgrowth of smelly bacteria (such as Gardnerella and Bacteroides) which are usually only present in small numbers.

These ‘smelly’ anaerobic bacteria thrive in the absence of oxygen by breaking down proteins to form chemicals known as amines which produce a characteristic ‘fishy’ odour, cause irritation and an unpleasant discharge.

As bacterial vaginosis is not a true infection, but an imbalance of bacteria that are normally present, it can be treated using remedies that restore the natural vaginal pH balance. Sometimes specific antibiotics are needed to get on top of the imbalance, but it is likely to recur unless you adopt measures that keep your vaginal pH balance acidic.

Why is it important to determine what type of vaginitis I have?

Bacterial Vaginosis, trichomoniasis and candidiasis (Yeast infection) are caused by different pathogens and must be treated differently. Each type of infection requires a specific treatment, and some infections have more than one cause.

What is the difference between Bacterial Vaginosis and Yeast infections?

Bacterial Vaginosis is the most common cause of vaginal infections and is about twice as common as Yeast infections. Bacterial Vaginosis is caused by an overgrowth of bacteria, such as Gardnerella or Prevotella bivia, whereas, Yeast infections are caused by an overgrowth of a fungus called Candida.

As the symptoms of both Yeast infections and Bacterial Vaginosis can be very similar, 2 out of 3 women frequently misdiagnose their symptoms and use the wrong treatment. One major recognizable difference between Bacterial Vaginosis and a Yeast infection is the bothersome unpleasant “fishy” odor associated with Bacterial Vaginosis, especially after having sex.

How Common is Bacterial Vaginosis?

Bacterial Vaginosis affects at least 1 in 3 adult women at some point in their lives. Worldwide, between 10% and 50% of women are affected in different countries at any one time, making it the most frequently occurring vaginal condition in women. As well as affecting women of childbearing age, it is also common after the menopause when levels of beneficial Lactobacilli bacteria naturally fall.

Bacterial Vaginosis is twice as common as thrush (Candida yeast overgrowth) and 2 out of 3 women with Bacterial Vaginosis wrongly diagnose themselves as having thrush as symptoms are similar.

What are the symptoms of Bacterial Vaginosis?

Most women (50-75%) do not experience symptoms of Bacterial Vaginosis, but when they do they typically have an abnormal vaginal discharge with an unpleasant odor. Some women report a strong fish-like odor, especially after intercourse. Discharge, if present, is usually white or gray and it can be thin.

Women with Bacterial Vaginosis may also have a burning sensation during urination or itching around the outside of the vagina, or both.

Other symptoms of Bacterial Vaginosis include:

  • Vaginal itching
  • Vaginal burning sensation
  • Vaginal irritation
  • Painful urination
  • Painful sexual intercourse
  • Vaginal discharge, usually thin and grayish/white; discharge may more noticeable after having sex
  • Foul “fishy” odor

These symptoms are often mistaken for vaginal candida (thrush) and will partially respond to antifungal treatments before recurring. If you think you have recurrent thrush, it’s worth considering whether or not you could have bacterial vaginosis.

The offensive smell of Bacterial Vaginosis worsens when the discharge mixes with alkaline fluids. This occurs during and after menstruation, when the smell may seem worse, and after having unprotected sex because blood and semen are both alkaline. The smell can also worsen if the discharge mixes with alkaline urine.

Are there any self-help remedies for Bacterial Vaginosis, available without a prescription?

You can overcome Bacterial Vaginosis without resorting to antibiotics if you take steps to restore the natural acidity of vaginal secretions, replenish friendly Lactobacillus bacteria, and correct any vitamin and mineral deficiencies that can reduce immunity – especially low vitamin D levels which are associated with Bacterial Vaginosis.

The first step is to restore the acid balance of the vagina which will allow healthy bacteria to flourish. A number of products are available to help prevent and treat Bacterial Vaginosis. Most contain lactic acid, while some also contain glycogen to provide fuel to promote the healthy growth of the normal bacteria (but cannot be used by anaerobic bacteria). GYNALAC contains these two ingredients as well as Sodium Hyaluronate which has a long-lasting moisturizing effect and promotes wound healing by enabling cells to retain moisture in the tissue.

Is Bacterial Vaginosis a sexually transmitted infection?

Bacterial Vaginosis is not a sexually transmitted infection. Any male sexual partners you might have would not need any treatment. In addition, you do not need to be sexually active to get Bacterial Vaginosis.

Should your partner receive treatment?

Bacteria associated with bacterial vaginosis are found in the normal male genital tract, and their presence could potentially increase the chance of a partner experiencing recurrent bacterial vaginosis after antibiotic treatment. However, a recent review of 7 trials, involving over 1000 people, found that giving antibiotic treatment to the sexual partners of women with bacterial vaginosis did not increase the rate of clinical or symptomatic improvement, and did not decrease the recurrence rate, compared with inactive placebo. While your male partner may be offered treatment, it is not guaranteed to make a difference.

If your partner is female, then it’s important that you both receive treatment. A review in the BMJ journal found that at least one in 4 and probably as many as 1 in 2 lesbians have bacterial vaginosis, and that both partners were affected in 87% of cases. Overall, lesbians were 2.5 times more likely to have BV than heterosexual women.

How do you get Bacterial Vaginosis?

What triggers the bacterial imbalance is poorly understood. It is related to loss of normal vaginal acidity which, in turn, can result from hormonal and lifestyle changes. Once intimate pH balance is disturbed, acid-loving Lactobacilli (beneficial bacteria) disappear and the growth of less beneficial bacteria is encouraged.

Hormonal factors affect vaginal acidity and glycogen levels which normally promote the growth of beneficial Lactobacilli. As a result, Bacterial Vaginosis often arises spontaneously before and during menstruation, then resolves mid-cycle, although recurrences are common

Any woman can get Bacterial Vaginosis. However, some activities or behaviors can upset the normal balance of bacteria in the vagina and put women at increased risk including:

  • Menstruation
  • Contraceptives
  • Having a new sex partner or multiple sex partners
  • Douching
  • Using antibiotics
  • Using vaginal medications
  • Smoking
  • Stress
  • Menopause
  • Diet
Is Bacterial Vaginosis caused by poor hygiene?

Poor hygiene does not cause Bacterial Vaginosis. On the contrary, excessive washing of the vagina may alter the normal balance of bacteria, which may make Bacterial Vaginosis more likely to develop.

Does Bacterial Vaginosis need to be treated?

Yes, Bacterial Vaginosis needs to be treated. Although Bacterial Vaginosis will sometimes clear up without treatment, all women with symptoms should be treated to avoid complications.

If left untreated, the bacteria may get up into the uterus or the fallopian tubes and cause more serious infections. The good news is that treating Bacterial Vaginosis lowers this risk. Male partners generally do not need to be treated, however, Bacterial Vaginosis may be spread between female sex partners.

Treatment is especially important in pregnant women. It is estimated that as many as 16% to 25% of pregnant women have bacterial vaginosis.1 Bacterial Vaginosis is associated with some serious pregnancy related consequences and it is estimated that it contributes up to 30% of premature deliveries.2

All pregnant women who experience the symptoms of Bacterial Vaginosis should consult their physician and be treated. All pregnant women who have had a premature delivery or low birth weight baby should also be considered for a Bacterial Vaginosis examination, regardless of symptoms, and should be treated if they have Bacterial Vaginosis.

How can you treat Bacterial Vaginosis?

There are a variety of effective treatment options available to treat Bacterial Vaginosis, including over the counter vaginal gels, prescription antibiotics, and alternative remedies. These will help to reduce the risk of experiencing any complications caused by the infection or recurrence.

GYNALAC is a Natural Heath Product and is an ideal treatment for patients who are concerned or unable to take antibiotics. One dose (3 mL) of GYNALAC daily for 7 consecutive days is clinically proven to be effective at relieving abnormal vaginal discharge and odor.

For women that are prone to having many recurrences of Bacterial Vaginosis, GYNALAC can also be used to maintain normal vaginal pH balance and help prevent recurrence of Bacterial Vaginosis. Apply one dose (3 mL) of GYNALAC daily for 3 consecutive days at the end of your menstrual cycle for a minimum of 6 months.

GYNALAC is also ideal for use after antibiotics to promote lactobacillus regrowth and prevent future recurrences of Bacterial Vaginosis. Apply one dose (3 mL) of GYNALAC daily for 7 consecutive days immediately following antibiotic therapy.

What are the possible complications of Bacterial Vaginosis?

When left untreated, Bacterial Vaginosis can cause serious complications and health risks, including:

  • Pregnancy complications: Pregnant women with Bacterial Vaginosis are more likely to have a premature or low birth weight baby. They also have a greater chance of developing another type of infection after delivery.
  • Sexually transmitted infections: Bacterial Vaginosis increases your risk of getting sexually transmitted infections, including the herpes simplex virus, chlamydia, and HIV.
  • Pelvic inflammatory disease: In some cases, Bacterial Vaginosis may lead to pelvic inflammatory disease, an infection of the reproductive organs in women. This condition can increase the risk of infertility.
  • Post surgical infections: Bacterial Vaginosis puts you at a higher risk for infections after surgeries affecting the reproductive system. These include hysterectomies, abortions, and caesarean deliveries.
Is it possible to prevent recurrences of Bacterial Vaginosis?

As many as 70% of women who have been treated for Bacterial Vaginosis experience recurrences within 90 days of treatment. Maintaining a balanced vaginal ecosystem is essential to prevent recurring infections.

You can use GYNALAC, even if you do not have a current infection, to maintain a healthy balance. Simply apply one dose (3 mL) of GYNALAC daily for 3 consecutive days at the end of your menstrual cycle for a minimum of 6 months.

Other tips to help lower your risk of developing Bacterial Vaginosis include:

  • Maintain a healthy lifestyle with regular exercise and a balanced diet.
  • If your doctor prescribes antibiotics, even for an unrelated condition, use GYNALAC, immediately after completing your course of antibiotics, to help maintain a natural and healthy vaginal balance.
  • Keep vaginal area clean and dry.
  • Avoid using perfumed intimate products (soaps, vaginal deodorants, etc.) as these irritate the vagina and disrupt the natural and healthy vaginal balance.
  • Avoid excessive washing (or douching) of the vagina: this may remove healthy bacteria lining the vagina.
  • Use a condom if you notice that sexual intercourse promotes symptoms. Semen is alkaline and can alter the natural pH of the vagina and predispose you to developing Bacterial Vaginosis.
Will Bacterial Vaginosis Affect My Chances for Getting Pregnant or Having a Healthy Pregnancy?

Bacterial Vaginosis is three times more common to be found in infertile women than fertile women. Bacterial Vaginosis, and other infections in general, can cause decreased fertility in a number of ways:

  • increasing inflammation and immune system activity, making a toxic environment for reproduction.
  • causing damage to sperm and vaginal cells.
  • interfering with the production of healthy cervical mucus during ovulation.
  • blocking the Fallopian Tubes through scar tissue damage from infections, so that sperm and egg can’t meet.

Bacterial Vaginosis is also associated with a two-fold increase in risk of preclinical pregnancy loss, sometimes called a chemical pregnancy, following IVF. Bacterial Vaginosis is also associated with increased rates of human papillomavirus (HPV) and HIV infection. For women with Bacterial Vaginosis present during pregnancy, there may be an increased risk of miscarriages, preterm birth, and low birth weight complications for the newborn, as well as postpartum infections.

What causes unpleasant vaginal odor?

An unpleasant vaginal odor usually results from a pH imbalance which has allowed for the flourishing of odor-causing micro-organisms in the vagina. The optimal range of vaginal pH is 3.8 to 4.5 (acidic), and when imbalanced, the pH can increase and become more alkaline (less acidic), allowing unfriendly bacterial to proliferate. Vaginal odor may be yeasty, signifying a Yeast Infection or fishy, sometimes signifying Bacterial Vaginosis.

Should women be douching if they have Bacterial Vaginosis?

Vaginal douching is not recommended by most medical professionals around the world. The consensus is that not only does vaginal douching have no benefits; it may also be harmful for your vagina in general. The vagina is an ecosystem wherein multiple types of organisms thrive, including bacteria and fungi. These organisms keep each other in check and maintain the health of the organ. These organisms help maintain the pH Levels (the alkaline to acidic ratio) within the vagina. Douching may actually disrupt the balance and cause harm by destroying one type of micro-organisms and letting the other proliferate, thus causing infections and other problems.
