Strong antibiotics for an STD: what to know

Strong antibiotics for an STD must be chosen for the specific infection, with testing, correct dosing and partner management. Antibiotics treat some sexually transmitted infections, but not every cause of genital symptoms. Taking a medicine without a diagnosis can mask symptoms, cause side effects and leave an infection untreated.

Chlamydia and gonorrhoea require different clinical decisions, and symptoms can overlap with irritation or another infection. Some infections cause no noticeable symptoms, so feeling well does not confirm that treatment worked. A clinician may use urine, swab or blood testing and ask about recent partners, pregnancy possibility and medication allergies. The result guides the drug, route and follow-up.

Arrange confidential testing and tell the clinician when the exposure occurred, what symptoms you have and which medicines you take. Avoid sex until a clinician says it is safe and the recommended treatment period is complete; follow specific advice about partners. Do not share antibiotics, skip doses or stop early because symptoms improve. Partners may need testing or treatment to prevent reinfection.

Seek prompt medical care for severe pelvic or testicular pain, fever, vomiting, genital sores, unusual bleeding, eye pain or a painful rash. Emergency help is needed for severe illness, faintness or rapidly worsening pain. If you may be pregnant or have had a high-risk exposure, contact a clinician promptly even without symptoms.

Ask which tests are needed, when results will be available, whether partners need assessment, how long to avoid sex, whether a retest is advised, and what symptoms should trigger urgent review.
