DOXYCYCLINE DELAYED-RELEASE - ORAL
COMMON BRAND NAME(S): Doryx
USES: This medication is used to treat a wide variety of bacterial infections, including those that cause acne. This medication is also used to prevent malaria. This medication is known as a tetracycline antibiotic. It works by stopping the growth of bacteria. This antibiotic treats only bacterial infections. It will not work for viral infections (such as common cold, flu). Unnecessary use or misuse of any antibiotic can lead to its decreased effectiveness.
OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional. This drug may also be used to treat a certain skin condition (rosacea).
HOW TO USE: This medication is best taken by mouth on an empty stomach, at least 1 hour before or 2 hours after a meal, usually 1 or 2 times daily or as directed by your doctor. Take this medication with a full glass of water (8 ounces/240 milliliters) unless directed otherwise. If stomach upset occurs, taking it with food or milk may help. However, doxycycline may not work as well if you take it with food or milk (or anything high in calcium - more details below ), so ask your doctor or pharmacist if you may take it that way. 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 aluminum, calcium, iron, magnesium, zinc, or bismuth subsalicylate. Some examples include antacids, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), quinapril, vitamins/minerals, dairy products (such as milk, yogurt), and calcium-enriched juice. These products bind with doxycycline, preventing your body from fully absorbing the drug. When using to prevent malaria, this medication is usually taken once daily. Take the first dose of this medication 1 to 2 days before travel or as directed by your doctor. Continue to take this medication daily while in the malarious area. Upon returning home, you should keep taking this medication for 4 more weeks. If you are unable to finish this course of doxycycline, contact your doctor. Swallow this medication whole. Do not crush or chew the medication. If you have difficulty swallowing the capsule, the capsule may be opened and the contents sprinkled onto cool applesauce and taken immediately as directed. If you have difficulty swallowing the tablet, the tablet may be broken up carefully and the contents (pellets) sprinkled onto cool applesauce and taken immediately as directed. Make sure not to crush or damage the pellets when breaking up the tablet. Do not prepare a supply in advance. Do not chew the food/medication mixture because doing so may cause the drug to be released too quickly, increasing side effects. Drink a glass of cool water after each dose to ensure complete swallowing of the medication. The dosage is based on your medical condition and response to treatment. For children, the dosage may also be based on weight. Antibiotics work best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. Continue to take this medication 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 to grow, which may result in a return of the infection. Tell your doctor if your condition persists or worsens.
SIDE EFFECTS: Stomach upset, diarrhea, nausea, or vomiting may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because he or she 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 immediately if any of these unlikely but serious side effects occur: sunburn (sun sensitivity), painful/difficult swallowing. Tell your doctor immediately if any of these rare but very serious side effects occur: vision changes (such as blurred vision), unusual/severe headache, change in the amount of urine. This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool. Use of this medication for prolonged or repeated periods may result in oral thrush or a new vaginal yeast infection.
