This product comes as a package with 14 separate dosing cards. Each card contains enough medication for 1 day (4 doses). Each dose contains 4 pills. For the 2 round pink tablets, chew thoroughly and swallow. For the 1 round white tablet and 1 black/yellow capsule, swallow whole with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. For best results, 1 dose (4 pills) must be taken 4 times daily.
Take this product at mealtimes and at bedtime for 14 days. Do not lie down for 10 minutes after taking this medication.
Take this medication 2 to 3 hours before or after taking any products containing magnesium, aluminum, or calcium. These products bind with tetracycline, preventing its full absorption. Some examples include quinapril, didanosine solution, vitamins/minerals, and antacids. Dairy products (such as milk, yogurt), calcium-enriched juice, sucralfate, iron, and zinc are also included.
Take this medication regularly to get the most benefit from it. Continue to take this medication and the acid blocker until the full prescribed amount is finished, even if symptoms disappear after a few days. Stopping the medication too early may result in a return of the infection/ulcer.
Tell your doctor if your condition lasts or gets worse.
Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: numbness/tingling of arms/legs, discolored teeth, mental/mood changes (such as confusion, anxiety, irritability, depression), difficult/painful swallowing, heartburn, fast/pounding heartbeat, ringing in the ears, frequent/painful urination, stiff/painful neck, signs of kidney problems (such as change in the amount of urine), signs of infection (such as a sore throat that doesn't go away, or a fever), easy bruising/bleeding, unusual weakness/tiredness, seizures, chest pain, symptoms of liver disease (such as loss of appetite, severe stomach/abdominal pain, yellowing eyes/skin, dark urine).

Tetracycline may rarely cause increased pressure around the brain (intracranial hypertension-IH). The risk of this side effect is greater for women of childbearing age who are overweight or who have had IH in the past.
