If you are diagnosed with an STD, most can fortunately be treated effectively. Many, however, cannot be cured. Oral or injected antibiotics are prescribed for gonorrhea, chlamydia and syphilis and patients usually respond well. There is no cure for genital warts, but flare-ups can be shortened with antiviral medications. HIV also has no cure but can be treated with a combination of medications. STDs are serious infections that can cause lifelong or recurring symptoms and side effects. It is important to practice safe sex and get tested often.
