A sexually transmitted disease (STD) means signs or symptoms of a sexually transmitted infection (STI) have developed. An STI happens when bacteria or a virus are spread through oral, genital, or anal sex. Some examples of STDs are HIV, chlamydia, syphilis, and gonorrhea.

DISCHARGE INSTRUCTIONS:

Return to the emergency department if:

• You have genital swelling or pain, or unusual bleeding.
• You have joint pain, a rash, swollen lymph nodes, or night sweats.
• You have severe abdominal pain.

Call your doctor if:

• You have a fever.
• Your symptoms do not go away or get worse, even after treatment.
• You have bleeding or pain during sex.
• You or your female partner may be pregnant.
• You have questions or concerns about your condition or care.

Drugs used to treat this and similar conditions

Medicines:

You may need any of the following:

• Antibiotics may be given for a bacterial infection. Post-exposure prophylaxis (PEP) means you take antibiotics within 72 hours of possible exposure. Your healthcare provider may give you a prescription so you can have antibiotics available before you need them.
• Antivirals may be given for a viral infection.
• Antifungals may be given for a fungal infection, such as a yeast infection.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.

Help prevent the spread of an STI:

Ask your healthcare provider for more information about the following safe sex practices:

• Use a male or female condom during sex. This includes oral, genital, or anal sex. Use a new condom each time. Condoms help prevent pregnancy and STIs. Use latex condoms, if possible. Lambskin (also called sheepskin or natural membrane) condoms do not protect against STIs. A polyurethane condom can be used if you or your partner is allergic to latex. Condoms should be used with a second form of birth control to help prevent pregnancy and STIs. Do not use male and female condoms together.
• Do not have sex with someone who has an STI or STD. This includes oral and anal sex.
• Limit sex partners. Ask about your partner's sex history before you have sex.
• Get screened regularly if you are sexually active. Common tests include chlamydia, gonorrhea, HIV, hepatitis, and syphilis.
• Tell your sex partners if you have an STI. Your partners may need to be tested and treated. Do not have sex while you are being treated for an STI. Do not have sex with a partner who is being treated.
• Ask about medicines to lower your risk for some STIs:
  • Vaccines can help protect you from hepatitis A, hepatitis B, and the human papillomavirus (HPV). The HPV vaccine is usually given at 11 years, but it may be given through 26 years to both females and males. Your provider can give you more information on vaccines to prevent STIs.
  • Pre-exposure prophylaxis (PrEP) may be given if you are at high risk for HIV. PrEP is taken every day to prevent the virus from fully infecting the body.
• If you are female, do not douche. Douching upsets the normal balance of bacteria found in your vagina. It does not prevent or clear up vaginal infections.

Follow up with your doctor as directed:

You may need more tests. If you have an STD, you may need immediate or ongoing treatment. Your doctor may also refer you to a specialist who can provide specific treatment. Write down your questions so you remember to ask them during your visits.
