Minocycline: what it treats and how to use it safely

Minocycline is a widely used antibiotic in the tetracycline family. People usually take it for acne, skin infections, and some respiratory or urinary infections. It’s available as a generic, which makes it one of the more affordable antibiotics if you shop smart.

Quick facts and common uses

Minocycline works by stopping bacteria from growing. For acne, doctors often prescribe 50–100 mg once or twice daily. For other infections the dose varies, so follow your prescriber's directions. Don’t try to guess the right dose — the length and strength depend on the infection.

Who should not take it? Avoid minocycline if you’re pregnant or under 8 years old — it can affect bone and tooth development. If you have severe liver disease or a known allergy to tetracyclines, tell your doctor before starting it.

Side effects, interactions, and safety tips

Common side effects include nausea, dizziness, and light sensitivity. Minocycline can also cause rare but serious reactions like liver inflammation or a condition called intracranial hypertension (bad headaches and vision changes). Stop and contact your doctor if you get sudden severe headaches, blurred vision, or yellowing of skin or eyes.

Certain products cut how well minocycline is absorbed. Don’t take it at the same time as antacids, calcium, iron supplements, or dairy-heavy meals. Warfarin users should watch INR closely — minocycline can affect blood thinning. When in doubt, ask your pharmacist about timing and interactions.

Want to save money? Generic minocycline is the cheapest option. Compare prices across pharmacies, use discount cards or coupons, and consider reputable online pharmacies that require a prescription. Never buy from sketchy sites that skip the prescription — fake antibiotics are a real risk.

Practical tips before you start: keep the full course even if you feel better, store tablets in a cool dry place, and wear sun protection because minocycline increases sunburn risk. If you miss a dose, take it as soon as you remember unless it’s nearly time for the next one — don’t double up.

If you have persistent acne or repeated infections, ask your doctor about long-term plans. Antibiotics aren’t always the only answer — topical treatments, skincare changes, or different meds may work better with fewer risks.
