If you suspect you have a yeast infection, it is important to consult a doctor, especially if you have never experienced these symptoms before. This will help ensure that you receive the proper treatment and rule out any other underlying issues. In most cases, over-the-counter antifungal creams like clotrimazole (e.g. Canesten) are effective for treating yeast infections. However, it is also recommended to get tested for sexually transmitted infections (STIs) if you have a new sexual partner or are engaging in unprotected sex. Some individuals can be carriers of STIs without showing symptoms, so it is important to prioritize your sexual health by getting tested regularly.
