This medication is used to treat moderate to severe acne in patients 12 years of age and older. It helps to reduce the number of pimples. Minocycline belongs to the class of antibiotics known as tetracyclines. It works by stopping the growth of bacteria that may worsen acne.
This antibiotic is approved to treat acne that is thought to be caused by a bacterial infection. It will not work for viral infections (e.g., common cold, flu). Unnecessary use or overuse of any antibiotic can lead to its decreased effectiveness.
Read the Patient Information Leaflet provided by your pharmacist before you start using this medication and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Take this medication by mouth with or without food, usually once daily or as directed by your doctor. 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 or 240 milliliters) unless your doctor directs you otherwise. Do not lie down for 10 minutes after taking this medication. For this reason, do not take it right before bedtime. You may take this medication with food or milk to lower the chance of irritating the esophagus and stomach unless your doctor directs you otherwise.
Take this medication 2-3 hours before or after taking any medications containing magnesium, aluminum, or calcium. Some examples include antacids, quinapril, certain forms of didanosine (chewable/dispersible buffered tablets or pediatric oral solution), vitamins/minerals, and sucralfate. Follow the same instructions if you also take bismuth subsalicylate, iron, and zinc. They bind with minocycline preventing its full absorption.
Dosage is based on your medical condition, weight, and response to therapy.
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 for the prescribed length of time. Do not skip doses. Stopping the medication too early or skipping doses may allow bacteria to continue to grow and increase the risk of developing resistant bacteria that are more difficult to treat.
Inform your doctor if your condition does not improve after 3 months of treatment or if it worsens.
Nausea, vomiting, diarrhea, lightheadedness, dizziness, unsteadiness, drowsiness, mild headache, mouth sores, or cough may occur. If any of these effects persist or worsen, notify 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 any of these unlikely but serious side effects occur: sunburn (sun sensitivity), muscle pain, difficult/painful swallowing, signs of kidney problems (such as change in the amount of urine, pink urine), brown/gray tooth discoloration, blue/gray/brown discoloration of the skin/lips/tongue/gums, numbness/tingling of the hands/feet, unusual tiredness, stopping of menstrual periods, new signs of infection (e.g., fever, chills, persistent sore throat).
Tell your doctor right away if any of these rare but very serious side effects occur: hearing changes (e.g., ringing in the ears, decreased hearing), easy bruising/bleeding.
Tetracycline drugs such as 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: 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 products or narcotic pain 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: rash, skin lesions/sores, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, new or worsening swelling/pain in the joints, swollen glands, loss of appetite/weight loss, chest pain, fast/irregular heartbeat, severe stomach/abdominal pain, yellowing eyes/skin, dark urine.
