What are tetracycline tablets or capsules?

TETRACYCLINE (Achromycin, Sumycin) is an antibiotic. It kills certain bacteria that cause infection, or stops their growth. Tetracycline treats many kinds of infections of the skin, bone, stomach, respiratory tract, sinuses, ear, and urinary tract. It also treats certain sexually transmitted diseases.

What should I tell my health care provider before I take this medicine?

They need to know if you have any of these conditions:

• kidney disease
• liver disease
• other chronic illness
• an unusual or allergic reaction to tetracycline antibiotics, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

How should I take this medicine?

Take tetracycline tablets or capsules by mouth. Follow the directions on the prescription label. Take tetracycline 1 hour before or at least 2 hours after eating. Swallow tablets or capsules whole with a full glass of water; take tablets or capsules in an upright or sitting position. Taking a sip of water first, before taking the tablets or capsules, may help you swallow them. If possible take bedtime doses at least 10 minutes before lying down. It is best to take tetracycline without food, but if it upsets your stomach take it with food. Avoid having dairy products, such as yogurt, milk, or cheese with your medicine; they can reduce the effect of tetracycline. Take your doses at regular intervals. Do not take your medicine more often than directed. Finish the full course prescribed by your prescriber or health care professional even if you think your condition is better. Do not stop taking except on your prescriber's advice.

What if I miss a dose?

If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses. There should be an interval of at least 4 to 6 hours between doses.

Where can I keep my medicine?

Keep out of the reach of children in a container that small children cannot open.

Store at room temperature between 15.30 degrees C (59.86 degrees F). Protect from light. Throw away any unused medicine after the expiration date.

What should I watch for while taking tetracycline?

Tell your prescriber or health care professional if your symptoms do not improve in 2 to 3 days.

Do not take tetracycline just before going to bed. It may not dissolve properly when you are lying down and can cause pain in your throat.
