Common Use

Tetracycline is a tetracycline antibiotic used to treat infections caused by certain bacteria. It works by slowing the growth of sensitive bacteria by interfering with the proteins they need to grow. This allows the body's natural defenses to eliminate the bacteria effectively.

Dosage and Directions

Take Tetracycline orally on an empty stomach, at least 1 hour before or 2 hours after eating. Always take it with a full glass of water. Do not lie down for 30 minutes after taking it. Avoid taking antacids containing aluminum, calcium, or magnesium, preparations with bismuth, iron, zinc, or sodium bicarbonate, or calcium-rich foods (such as milk, dairy products, or calcium-enriched juices) within 2 to 3 hours before or after taking Tetracycline. Consult your doctor if you have any questions. Complete the full course of treatment, even if you feel better after a few days.

Before using Tetracycline, discuss your medical history with your doctor, especially if you have:

• Kidney or liver problems
• Allergies to medicines, foods, or other substances
• Pregnancy, plans to become pregnant, or breastfeeding
• Current use of prescription or non-prescription medicines, herbal products, or dietary supplements
• Diarrhea, stomach infections, or kidney issues

Drug Interactions

Inform your doctor about all medications you are taking, especially:
