    Uses

    This medication is used to treat moderate to severe acne in people 12 years and older. It helps to reduce the number of pimples. Minocycline belongs to a class of drugs known as tetracycline antibiotics. It works by stopping the growth of bacteria that may make acne worse.

    This antibiotic treats acne that is thought to be caused by a bacterial infection. It will not work for viral infections (such as common cold, flu). Using any antibiotic when it is not needed can cause it to not work for future infections.

    How to use minocycline

    Read the Patient Information Leaflet if available from your pharmacist before you start taking minocycline and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

    Take this medication by mouth with or without food as directed by your doctor, usually once a day. Do not crush or chew extended-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.

    Take each dose with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this medication. For this reason, do not take it right before bedtime. You may take this medication with food to lessen the chance of irritating the esophagus or stomach unless your doctor directs you otherwise.

    Take this medication 2 to 3 hours before or after taking any products containing aluminum, calcium, iron, magnesium, or zinc. Some examples include antacids, didanosine solution, quinapril, vitamins/minerals, dairy products (such as milk, yogurt), and calcium-enriched juice. These products bind with minocycline, preventing your body from fully absorbing the drug.

    The dosage and length of treatment are based on your medical condition, weight, and response to treatment.

    For the best effect, take this antibiotic at evenly spaced times. To help you remember, take this medication at the same time every day.

    Continue to take this medication for the prescribed length of time. Do not skip doses. Stopping the medication too early or skipping doses may allow bacteria to grow and make your treatment work less well.

    Tell your doctor if your condition does not get better or if it gets worse.

    Side Effects

    Nausea, vomiting, diarrhea, lightheadedness, dizziness, or a feeling of spinning may occur. If any of these effects last or get worse, 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 right away if you have any serious side effects, including: painful/difficult swallowing, hearing changes (such as ringing in the ears, decreased hearing), joint stiffness/pain/swelling, signs of kidney problems (such as change in the amount of urine, pink urine), signs of liver problems (such as loss of appetite, stomach/abdominal pain, yellowing eyes/skin, dark urine), yellow-gray-brown tooth discoloration, blue-gray skin/tongue/lips/gums).

    Minocycline 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 minocycline is stopped; however, there is a chance of permanent vision loss or blindness. Get medical help right away if you have: severe/lasting headache, vision changes (such as blurred/double vision, decreased vision, sudden blindness), nausea/vomiting that doesn't stop.

    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. Tell your doctor right away if you develop: diarrhea that doesn't stop, abdominal or stomach pain/cramping, blood/mucus in your stool.

    Do not use anti-diarrhea products or narcotic pain medications if you have any of these symptoms because these products may make them worse.

    Use of this medication for prolonged or repeated periods may result in oral thrush or a new yeast infection. 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: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, fever, swollen lymph nodes.

    This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

    Minocycline may cause live bacterial vaccines (such as typhoid vaccine) to not work as well. Do not have any immunizations/vaccinations while using this medication unless your doctor tells you to.

    Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).

    Children younger than 8 years may be more sensitive to the side effects of minocycline, especially tooth discoloration. Tooth discoloration has also occurred in older children and in young adults. Discuss the risks and benefits of this medication with the doctor.

    Tell your doctor if you are pregnant or plan to become pregnant. You should not become pregnant while using minocycline. Minocycline may harm an unborn baby. If you become pregnant, talk to your doctor right away about the risks and benefits of this medication.

    Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

    Some products that may interact with this drug are: retinoid medications taken by mouth (such as acitretin, isotretinoin), strontium.

    Although most antibiotics are unlikely to affect hormonal birth control such as pills, patch, or ring, a few antibiotics (such as rifampin, rifabutin) can decrease their effectiveness. This could result in pregnancy. If you use hormonal birth control, ask your doctor or pharmacist for more details.

    This medication may interfere with certain lab tests (such as urine catecholamine levels), possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

    Missed Dose
