Table of contents:

Sumycin (generically known as tetracycline hydrochloride) is an antibiotic medication used to treat a variety of bacterial infections, such as urinary tract infections, acne, gonorrhea, and more. It can be used to treat respiratory infections, urinary tract infections, and skin infections.

Tetracycline is in a class of medications called tetracycline antibiotics. It works by stopping the growth of bacteria. It prevents bacteria from making certain proteins, which stops them from multiplying and spreading the infection.

Use and Dosage

Tetracycline is a tablet that should be taken by mouth as prescribed by the doctor, usually 2 or 4 times daily. It works best when taken on an empty stomach, either 1 hour before or 2 hours after meals. If stomach upset occurs, ask the doctor if the medication can be taken with food. Each dose should be taken with a full glass of water, unless directed otherwise by the doctor. Do not lie down for at least 10 minutes after taking the tablet, so do not take it right before bedtime.

If you take any products containing magnesium, aluminum, or calcium, such as antacids, quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, sucralfate, dairy products (like milk, yogurt), calcium-enriched juice, bismuth subsalicylate, iron, or zinc, take Tetracycline 2 to 3 hours before or after taking these products. These products can bind with Tetracycline and prevent its full absorption.

The dosage of Tetracycline is based on your medical condition and response to treatment. The dosage for children older than 8 years of age is also based on weight. To ensure the best effect, take Tetracycline at evenly spaced times. It can be helpful to take the medication at the same time(s) every day to remember.

Continue taking Tetracycline until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may allow bacteria to continue growing, which can lead to a relapse of the infection.
