Why is Tetracycline prescribed?

Tetracycline, a "broad-spectrum" antibiotic, is used to treat bacterial infections such as Rocky Mountain spotted fever, typhus fever, and tick fevers; upper respiratory infections; pneumonia; gonorrhea; amoebic infections; and urinary tract infections. It is also used to help treat severe acne and to treat trachoma (a chronic eye infection) and conjunctivitis (pinkeye). Tetracycline is often an alternative drug for people who are allergic to penicillin.

Most important fact about Tetracycline

Tetracycline should not be used during the last half of pregnancy or in children under the age of 8. It may damage developing teeth and cause permanent discoloration.

How should you take Tetracycline?

Tetracycline should be taken exactly as prescribed by your doctor. Be sure to use the entire prescription. If you are taking a liquid form of the drug, shake well before using.

Do not use outdated tetracycline. Outdated tetracycline is highly toxic to the kidneys.

Do not take antacids containing aluminum, calcium, or magnesium (e.g., Mylanta, Maalox) while taking this medication. They will affect the absorption of the drug.

Take tetracycline 1 hour before or 2 hours after meals. Foods, milk, and some other dairy products affect absorption of the drug.

Tetracycline should be continued for at least 24 to 48 hours after your symptoms have subsided.

• If you miss a dose...
  Take it as soon as you remember. If it is almost time for your next dose and you take tetracycline once a day (e.g., for acne), take the dose you missed, and then take the next one 10 to 12 hours later; if you take it twice a day, take the dose you missed, and then take the next one 5 to 6 hours later; if you take 3 or more doses a day, take the one you missed, and then take the next one 2 to 4 hours later. Then go back to your regular schedule.

• Storage instructions...
  Store capsules at room temperature. Keep the liquid form of tetracycline in the refrigerator, but do not allow it to freeze.
