Antibiotic (Tetracycline class)
Last reviewed June 2026
Who is this for?
Tetracycline is an antibiotic that works by stopping bacteria from growing and multiplying in your body, helping your immune system fight off the infection.
Binds to the bacterial 30S ribosomal subunit, inhibiting protein synthesis by preventing aminoacyl-tRNA attachment and causing bacteriostatic effects against susceptible organisms. Exhibits broad-spectrum activity against gram-positive bacteria, gram-negative bacteria, atypical pathogens, and some protozoa.

Explore this drug
Adults usually take 1 capsule (250 mg) four times a day, or 2 capsules (500 mg) four times a day depending on the infection. Take it on an empty stomach — at least 1 hour before food or 2 hours after food. Swallow with a full glass of water. Do not take it with milk, yoghurt, or malt drinks as they stop the drug from working properly.
If you miss a dose, take it as soon as you remember. But if it is almost time for your next dose, skip the missed one and continue your normal schedule. Do not double up to make up for the missed dose.
Important for antibiotics
Always complete the full course even if you feel better. Stopping early can cause the infection to return and become drug-resistant.
Always complete the full course of tetracycline even if you feel better — stopping early creates stubborn bacteria that won't respond to treatment next time. Buy only from licensed pharmacies and check the expiry date carefully, as expired tetracycline is actually dangerous unlike most other drugs. Popular Nigerian brands include Nemel Tetracycline, Maxcyclin, Salmycin 250, and Latetra — make sure the pack is properly sealed.
Do not take with milk, cheese, yoghurt, or antacids like aluminium hydroxide (e.g. Gestid) — they block the drug from entering your blood. Tetracycline reduces how well birth control pills work, so use additional protection. Avoid taking with iron supplements or blood tonics as they reduce the drug's effectiveness.
Check your specific combination
Is it safe to take Tetracycline with your other drugs?
Tetracycline is NOT safe during pregnancy or breastfeeding — it can harm the baby's teeth, bones, and liver development, so consult your doctor for a safer alternative.
Store in a cool, dry place away from direct sunlight and heat — Nigerian weather can spoil this drug quickly. Do not use tetracycline that has expired or changed colour, as expired tetracycline can become poisonous and damage your kidneys. Keep away from children.
