Frequently asked questions

For uncomplicated vaginal thrush, a single dose is often enough. Recurrent or severe infections need a doctor's plan.

Symptoms of thrush often improve within a few days, though it may take longer to clear fully.

Should my partner be treated?

Partners usually do not need treatment unless they also have symptoms. Ask your doctor.
