Terconazole 0.8% cream is a prescription antifungal medication used to treat vaginal yeast infections, known medically as vulvovaginal candidiasis. It works against the fungus Candida, which is the organism responsible for most vaginal yeast infections. Unlike many over-the-counter yeast infection treatments, terconazole requires a prescription and is typically used as a short three-day course.
How Terconazole Treats Yeast Infections
Yeast infections happen when Candida, a fungus that normally lives in small amounts in the vagina, overgrows and causes symptoms like itching, burning, and discharge. Terconazole belongs to a class of drugs called azole antifungals, which kill the fungus by disrupting its ability to build and maintain its cell walls. Specifically, it blocks the production of a key component called ergosterol, which fungal cells need to keep their outer membranes intact. Without it, the fungal cells break down and die.
Terconazole has been shown to be fungicidal against Candida albicans, the species responsible for the majority of vaginal yeast infections. The CDC includes terconazole 0.8% cream as a recommended prescription treatment for uncomplicated vulvovaginal candidiasis.
How It’s Applied
The standard regimen for terconazole 0.8% cream is 5 grams inserted vaginally once daily for three days. The cream comes with a prefilled applicator that you use to deposit the medication inside the vagina, typically at bedtime to reduce leakage. You complete the full three-day course even if symptoms improve earlier, since stopping too soon can allow the infection to return.
One important practical detail: an ingredient in the cream base can weaken latex. If you use latex condoms or a diaphragm, avoid them for at least 72 hours after your last application. Non-latex alternatives are fine during this window.
Common Side Effects
In clinical trials involving 231 patients, the most frequently reported side effect was headache, which affected about 21% of users. That number is higher than many people expect from a vaginal cream, but it’s a well-documented effect of this medication class. Other side effects reported at lower rates included menstrual cramps (6%), genital burning and itching (5%), and abdominal pain (about 3%). Fever occurred in roughly 1% of users.
Some genital burning or itching can be hard to distinguish from the yeast infection itself. Mild irritation at the application site is generally not a reason to stop treatment, but worsening symptoms or signs of an allergic reaction (significant swelling, hives, difficulty breathing) would be.
Use During Pregnancy
Terconazole is not recommended during the first trimester of pregnancy. During the second and third trimesters, it may be used if the benefit is considered to outweigh potential risks. Yeast infections are common during pregnancy due to hormonal shifts, so your prescriber will weigh the timing and severity of the infection when choosing a treatment. If you’re breastfeeding, let your provider know before starting treatment, as the safety data during lactation is limited.
Why It’s Prescription Only
Most people who search for this cream have either been prescribed it or are wondering why their doctor chose it over an over-the-counter option like miconazole or clotrimazole. Terconazole is often prescribed when OTC treatments haven’t worked, when the infection may involve a less common Candida species, or when a healthcare provider wants a shorter, more potent course. Because it requires a prescription, your provider has already confirmed the diagnosis, which matters since bacterial vaginosis and other conditions can mimic yeast infection symptoms but need entirely different treatment.
If your symptoms haven’t improved within a few days of finishing the three-day course, or if they return shortly after, that may signal a resistant strain or recurring infection pattern that needs a different approach.
