Why do I get frequent UTIs after using contraceptive gel?

Question

Hello doctor,

I am 33 years old and really need effective birth control since we do not want children right now, but this is affecting my relationship and quality of life. I read online that contraceptive gel can disrupt normal vaginal bacteria, but my doctor says it is rare.

I have been using this contraceptive gel containing Lactic acid, Citric acid, and Potassium bitartrate for the past four months because I cannot take hormonal birth control due to a history of blood clots in my legs. The gel works by changing vaginal pH, but I am getting constant yeast infections and UTI since starting it. I have had three UTIs, already treated with Nitrofurantoin and Fluconazole for yeast, but they keep coming back.

The burning and itching are so bad after using the contraceptive gel that sex has become painful for my partner and me. My gynecologist did cultures, and everything came back normal, but symptoms persist. I also noticed increased vaginal discharge that has a strong chemical smell, which is embarrassing. I tried switching to different applicators, thinking it might be contamination, but there is no improvement.

Are there other non-hormonal options that will not cause these infections?
Can long-term use of contraceptive gel cause permanent damage to vaginal health?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

I am really sorry you are dealing with this, because the condition you are describing sounds physically uncomfortable, emotionally draining, and very disruptive to intimacy and daily life, and it makes sense that you feel frustrated and worried.

The contraceptive gel containing Lactic acid, Citric acid, and Potassium bitartrate works by keeping the vaginal environment acidic, but in some people, that change in pH can irritate the vaginal lining and disrupt the normal protective bacteria, even if cultures come back normal. That irritation alone can cause burning, itching, pain with sex, chemical-smelling discharge, and symptoms that feel exactly like recurrent yeast infections or urinary tract infections, even when no clear infection is found.

The fact that your symptoms flare after using the gel and have persisted despite treatment strongly suggests that your vaginal tissue is reacting to the product itself rather than this being a hygiene or contamination issue.

While permanent damage to vaginal health is very unlikely, ongoing inflammation and discomfort are good reasons to stop using it, because quality of life and sexual comfort matter.

The reassuring part is that once the irritant is removed, the vaginal environment usually recovers over time. Given your history of blood clots, it is very reasonable to avoid estrogen-containing contraception, and you do still have effective non-hormonal options.

A copper intrauterine device is one of the most reliable non-hormonal methods and does not alter vaginal pH or bacteria, though it can increase menstrual bleeding and cramps in some people. Barrier methods such as condoms with non-spermicidal lubricant may be better tolerated than pH-altering gels.

Some couples also combine condoms with fertility awareness methods for added protection, though this requires careful education and consistency. If pregnancy prevention is absolutely critical right now, using a copper intrauterine device is a good option.

In the meantime, stopping the gel and allowing time for the vaginal tissue to heal, sometimes with soothing measures like avoiding irritants, using plain water only externally, and possibly short-term treatments recommended by a gynaecologist, can help symptoms settle.

You are not imagining this, and you are not alone in having sensitivity to non-hormonal contraceptive gels, even if it is described as uncommon. It is reasonable to advocate for yourself and say that this method is no longer acceptable for your body. With the right alternative and some time for recovery, there is a very good chance your symptoms will improve, and intimacy can become comfortable again.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
