Tetracycline is used for:

Treating infections caused by certain bacteria.

Tetracycline is a tetracycline antibiotic. It works by slowing the growth of sensitive bacteria by interfering with the production of proteins needed by the bacteria to grow. Slowing the bacteria's growth allows the body's defense mechanisms to destroy them.

Do NOT use Tetracycline if:

• you are allergic to any ingredient in Tetracycline or other tetracycline antibiotics (eg, doxycycline)
• you are currently taking acitretin or methoxyflurane

Contact your doctor or health care provider right away if any of these apply to you.

Before using Tetracycline :

Some medical conditions may interact with Tetracycline. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

• if you are pregnant, planning to become pregnant, or are breast-feeding
• if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
• if you have allergies to medicines or other substances
• if you have diarrhea, a stomach infection, or kidney problems

Some MEDICINES MAY INTERACT with Tetracycline. Tell your health care provider if you are taking any other medicines, especially any of the following:

• Acitretin or isotretinoin because side effects, such as increased pressure in the fluid surrounding the brain, may occur
• Digoxin, methotrexate, methoxyflurane, or oral anticoagulants (eg, warfarin) because their actions and side effects may be increased by Tetracycline
• Atovaquone, lithium, oral contraceptives (birth control pills), or penicillins (eg, amoxicillin) because their effectiveness may be decreased by Tetracycline

This may not be a complete list of all interactions that may occur. Ask your health care provider if Tetracycline may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use Tetracycline :

Use Tetracycline as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Take Tetracycline on an empty stomach at least 1 hour before or 2 hours after a meal.
• Take Tetracycline with a full glass of water (8 oz/240 mL). Do not lie down for 30 minutes after taking Tetracycline.
• Do not take antacids containing aluminum, calcium, or magnesium; preparations containing bismuth, iron, zinc, or sodium bicarbonate; or calcium rich foods (eg, milk, dairy products, calcium-enriched juices) within 2 to 3 hours before or after taking Tetracycline. These products bind with Tetracycline , preventing its full absorption.
• To clear up your infection completely, continue using Tetracycline for the full course of treatment even if you feel better in a few days.
• If you miss a dose of Tetracycline , take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use Tetracycline.

Important safety information:

• Tetracycline may cause dizziness or blurred vision. Do not drive, operate machinery, or do anything else that could be dangerous until you know how you react to Tetracycline. Using Tetracycline alone, with certain other medicines, or with alcohol may lessen your ability to drive or to perform other potentially dangerous tasks.
• If severe diarrhea, stomach pain/cramps, or bloody stools occurs, contact your doctor at once. This could be a symptom of a serious side effect requiring immediate medical attention. Do not treat diarrhea without consulting your doctor.
• It is important to use Tetracycline for the full course of treatment. Failure to do so may decrease the effectiveness of this treatment and may increase the risk that bacteria will no longer be sensitive to Tetracycline and will not be able to be treated by this or certain other antibiotics in the future.
