Mycoplasma Genitalium Infection: Care Instructions

Overview

Mycoplasma genitalium (M. genitalium) is a type of bacteria that spreads through sexual contact (sexually transmitted infection, or STI). You may also hear it called Mgen or MG.

Symptoms include discharge from the penis, vagina, or anus. Some people have burning and pain when they urinate. Or they may have itching inside the urethra or vagina. The infection can also cause pain during sex or bleeding between periods. Some people have no symptoms.

An M. genitalium infection is treated with antibiotics. Treatment can help you feel better and stop the spread of infection. It may also prevent more severe problems. Your doctor may suggest that your most recent sex partner or partners get tested too.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How can you care for yourself at home?

• Take your antibiotics as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.

• Don't have sex with anyone while you are being treated. Ask your doctor when it is okay for you to have sex again.

• Follow your doctor's advice for telling your most recent sex partner or partners that you have a Mycoplasma genitalium infection. They may need to get tested too.

How can you prevent it?

• Limit your sex partners. Sex with one partner who has sex only with you can reduce your risk of getting a sexually transmitted infection (STI).

• Talk with your partner or partners about STIs before you have sex. Find out if they are at risk for an STI. Remember that it's possible to have an STI and not know it.

• Avoid having sex if you (or any partners) have symptoms of an infection or if you are being treated for an STI.

• Use a condom every time you have sex. Condoms are the only form of birth control that also helps prevent STIs.

• Don't share sex toys. But if you do share them, use a condom and clean the sex toys between each use.
