This medication is used to treat a certain type of skin condition called rosacea. It helps to reduce the number of pimples and bumps on the face, but it may not decrease redness. It works by reducing skin inflammation caused by rosacea.
Although doxycycline belongs to the class of antibiotics known as tetracyclines, this product does not work as an antibiotic because it does not stop the growth of bacteria. Therefore, do not use this product to treat any infection, including viral infections (such as the common cold, flu). Use this medication only as prescribed by your doctor.
How to use Doxycycline IR-DR
This medication is best taken by mouth on an empty stomach, at least 1 hour before or 2 hours after a meal, usually once daily in the morning or as directed by your doctor. Swallow the capsules whole. Do not crush or chew the capsules. Doing so can release all of the drug at once, increasing the risk of side effects.
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 at least 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, didanosine 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.
For the best effect, take this antibiotic at evenly spaced times. To help you remember, take it at the same time each day. Do not skip doses or take more of this medication than prescribed.
Tell your doctor if your condition does not improve or if it worsens.
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 right away if you have any serious side effects, including: difficult/painful swallowing, brown/gray tooth discoloration, blue/gray/brown discoloration of the skin/lips/tongue/gums, unusual tiredness, signs of kidney problems (such as change in the amount of urine), hearing changes (e.g., ringing in the ears, decreased hearing), severe stomach/abdominal pain, persistent nausea/vomiting.
Tetracycline drugs such as doxycycline may rarely cause a serious increase in pressure inside the skull (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. If IH develops, it usually goes away after doxycycline is stopped; however, there is a chance of permanent vision loss or blindness. Get medical help right away if you have: persistent/severe headache, vision changes (such as blurred/double vision, decreased vision, sudden blindness), persistent nausea/vomiting.
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 or opioid medications if you have any of the following symptoms because these products may make them worse. Tell your doctor right away 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 (fungal infections). Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: fever that doesn't go away, new or worsening lymph node swelling, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.
