Vaginal yeast Infections, also known as Candidiasis, are the most common infections women encounter worldwide. Candidiasis is caused by a fungal specie, particularly yeast, known as Candida albicans. This fungal microbe, though, resides on human skin naturally but, due to unfavorable conditions, thrives and proliferates at its maximum to cause infection. The same specie causes penile infection in males and oral thrush in men and women. However, female yeast infections are common due to anatomical, physiological, and medical conditions.

Moreover, these yeast infections are treated with antifungals available in oral, topical, and suppository dosage forms. Though antifungals treat yeast infections well, many people are concerned about why does yeast infection medicine burn? It\’s a very contentious issue. Many antifungal topical medications are highly potent that they may cause vaginal burning.

Other conditions might be on the patient end, such as vaginal soreness, cracking, having intercourse during yeast infection treatment, or using intrauterine devices. Moreover, interactions with other drugs may cause vaginal irritation, rash, or burning. Our formulation does not burn. However, it causes a warm sensation after application that quickly subsides. Here is an explanation of how and why.

What Is Yeast Infection Medicine?

Yeast infection medicines are those drugs that contain active antifungals in appropriate amounts according to the specifications of prescribed pharmacopeia. Most antifungal medications work by inhibiting fungal ergosterol\’s biosynthesis, which maintains the integrity of fungal cell membranes. Blockade of its synthesis results in decreased ergosterol, making fungal cells susceptible to destruction by antifungals. These yeast infection medicines are both prescribed or over-the-counter drugs.

Nevertheless, since every drug is associated with some common and rare side effects, it\’s best to take them when recommended after an accurate diagnosis. Furthermore, it\’s crucial to complete antifungal treatment for a prescribed duration based on the severity and potency of medicines. Consult your doctor if you are taking other medications to treat other medical conditions to avoid drug-drug, drug-disease, drug-allergy, and drug-food interactions.

Why Does Yeast Infection Medicine Burn?

Though every medicine has some side effects, common or rare, mentioned by the manufacturer on the leaflet inside the packaging for legal purposes, it\’s only sometimes true that humans administering antifungal medicine will get the side effects. Usually, oral yeast infection medicines do not cause vaginal burning or irritation since these are topical manifestations. Oral antifungals cause GI issues such as nausea, vomiting, diarrhea, abdominal pain, or headache. In addition, topical yeast infection medicines, including creams, ointments, and gels, may cause vaginal irritation or burn under certain conditions.

Why Does Yeast Infection Medicine Burn? Typically, the vagina and vulva produce mucus secretions to protect the reproductive tract against harmful microbes and other foreign invaders. Moreover, it lubricates the vaginal cavity and helps maintain a good acidic balance. These secretions can also absorb chemicals that may produce a warm or burning sensation due to interactions with active ingredients or excipients. Therefore, some patients complain about burning after using yeast infection medicine. Anyhow, there may be other causative factors of vaginal burning while on yeast infection treatment.
