Medical Editor: John P. Cunha, DO, FACOEP
Minocin (minocycline hydrochloride) is a tetracycline antibiotic used to treat many different bacterial infections, such as urinary tract infections, respiratory infections, skin infections, severe acne, gonorrhea, tick fever, chlamydia, and others. Common side effects of Minocin include dizziness, tired feeling, spinning sensation, joint or muscle pain, discoloration of your skin or nails or gums, nausea, diarrhea, upset stomach, skin rash or itching, swollen tongue, or vaginal itching or discharge.
The usual dosage of Minocin is 200 mg initially followed by 100 mg every 12 hours. Minocin may interact with other antibiotics, acetaminophen (Tylenol), isotretinoin, methotrexate, antifungals, blood thinners, cholesterol medications, heart or blood pressure medicines, migraine headache medicines, or NSAIDs (non-steroidal anti-inflammatory drugs). Tell your doctor all medications and supplements you use. Minocin should not be used during pregnancy. It could harm the fetus or cause permanent tooth discoloration later in life. Tell your doctor if you become pregnant during treatment. Minocin can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) while using minocycline. This drug passes into breast milk and may affect bone and tooth development in a nursing baby. Do not breastfeed while taking Minocin.
