Tetracycline is used to treat infections caused by bacteria including pneumonia and other respiratory tract infections, as well as certain infections of skin, eye, lymphatic, intestinal, genital and urinary systems. It is also used along with other medications to treat acne and can be used in patients who cannot be treated with penicillin to treat certain types of food poisoning. Tetracycline is in a class of medications called tetracycline antibiotics. It works by preventing the growth and spread of bacteria.

Uses and Dosage

Follow your doctor’s instructions and take this medication orally, typically 2 or 4 times daily. Tetracycline is most effective when taken on an empty stomach, either one hour before or two hours after meals. If you experience stomach upset, consult your doctor about the possibility of taking the medication with food. Drink a full glass of water (8 ounces or 240 milliliters) with each dose, unless otherwise directed by your doctor. Avoid lying down for at least 10 minutes after taking the medication, so it’s advisable not to take it right before bedtime.

Ensure a gap of 2 to 3 hours before or after taking any products containing magnesium, aluminum, or calcium. Examples include antacids, quinapril, specific forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, and sucralfate. Apply the same guidelines to dairy products (such as milk, yogurt), calcium-enriched juice, bismuth subsalicylate, iron, and zinc, as these items can bind with tetracycline, hindering its complete absorption.

The dosage is determined by your medical condition and response to treatment. In children older than 8 years, the dosage is also weight-dependent.

For optimal results, take this antibiotic at evenly spaced intervals. Establish a routine by taking the medication at the same time(s) daily.

Continue the course of this medication until you complete the full prescribed amount, even if symptoms improve within a few days. Prematurely stopping the medication may lead to a recurrence of the infection.

Inform your doctor if your condition persists or worsens.
