This product is taken orally.
Why is it prescribed?
Minocycline is used to treat many infections caused by susceptible types of bacteria. This material will be limited to the treatment of infections of the respiratory tract (e.g. pneumonia).
Use exactly as prescribed. Store this medication at room temperature, protected from light and moisture.
PMS-Minocycline can be taken with or without food but should be taken with a full glass of water or other liquids to ensure it reaches the stomach. Avoid use of antacids and oral iron preparations. If antacids must be taken, take 2 to 3 hours after PMS-Minocycline®.
Take PMS-Minocycline at even intervals around the clock as prescribed (e.g. every 12 hours translates to twice a day) until finished. Failure to take the complete course can result in incomplete elimination of the bacteria which can lead to a relapse of the infection. The prescribed course generally lasts a few days longer than symptoms of the infection (e.g. fever). Treatment usually lasts 7-14 days. If you miss a dose, take it as soon as possible. If it is almost time for your next dose, do not take 2 doses at once (unless you have been instructed to do so). Contact your pharmacist if you are not sure what to do.
PMS-Minocycline may produce an allergic reaction which can range in severity from a mild rash or itching to a life-threatening reaction. Contact your doctor or pharmacist if you experience rash, itching, fever, difficulty breathing, chest tightness or anything else that alarms you.
If diarrhea occurs (severe or persistent), contact your doctor or pharmacist. Do not treat diarrhea without being instructed to do so.

Minocycline is an antibiotic medication that kills various bacteria. It works by inhibiting the bacteria's production of protein. This slows and prevents it's growth and reproduction. The effectiveness of minocycline depends on factors such as dose, concentration in the blood as well as other body fluids and tissue, and susceptibility of the organism. Minocycline affects only certain types of bacteria sensitive to its antibiotic action. Infections caused by bacteria that are not sensitive to minocycline will not show improvement after taking this medication.
Along with its needed effects, minocycline may cause some unwanted or undesirable effects. Generally, minocycline is well tolerated and many people will not experience unwanted effects. The frequency and severity of these effects is dependent on many factors including dose, duration of therapy and individual susceptibility. Possible unwanted effects include:
- vertigo (feeling of whirling sensation)
- stomach upset
- appetite loss
- discoloration of bones and teeth in children under the age of 13 and in children of mothers given minocycline during the last half of her pregnancy
- sensitivity to sunlight
- allergic reaction (e.g. rash, itching, difficulty breathing)
- inflammation of the lining of the mouth
- inflammation of the tongue
- sore mouth and tongue
Unwanted effects associated with the stomach should be reported to your pharmacist if they persist or become bothersome. Any uncommon or rare, unwanted effects should be reported to your pharmacist immediately.
Allergic reactions can occur with minocycline use. People with a history of allergy, asthma, hay fever or hives seem to be more susceptible to these reactions. The reaction can be immediate and severe. Allergic symptoms include wheezing, hives, itching, swelling, spasms in the throat and breathing tubes, joint and muscle pain, difficulty breathing, fever and skin rashes. Nausea and vomiting are not symptoms of an allergic reaction.
Use of minocycline in children umder 13 years of age is not recommended. Use of minocycline in this age group, during tooth development has been known to cause permanent tooth discoloration. It has also been known to decrease bone growth when given to premature infants.
Avoid prolonged exposure to direct sunlight or tanning beds. Some people may develop a sensitivity to sunlight while taking minocycline that usually presents itself in the form of a rash and/or a painful burn. Sun screen and protective clothing should be worn as a precautionary measure when exposed to direct sunlight. Some people being treated with minocycline experience dizziness, light-headedness, vertigo (feeling of whirling sensation) and headache. These symptoms may disappear during therapy and usually disappear rapidly when therapy is finished. Minocycline belongs to the tetracycline group of antibiotics. If you are allergic to a tetracycline (e.g. doxycycline, tetracycline), you may also be allergic to minocycline.
Antacids containing aluminum, magnesium or calcium and oral iron preparations interfere with the absorption of minocycline and should be avoided.
Taking the antibiotic repeatedly or for prolonged periods may result in bacterial or fungal overgrowth which can lead to a second infection. When this occurs, the minocycline may need to be stopped and another antibiotic prescribed to treat the new infection.
Diarrhea can develop while taking minocycline. This is sometimes caused by an overgrowth of bacteria in the gut that are not killed by the antibiotic. In severe cases, this may be life threatening and would require treatment with other antibiotics. In mild cases, symptoms disappear shortly after the drug is discontinued.
