Minocin Precautions

Serious side effects can occur including:

  • Harm to an unborn baby. If you are pregnant talk to your doctor about the risks associated with taking minocycline during pregnancy.
  • Permanent teeth discoloration. Minocycline may permanently turn a baby or child's teeth yellow-grey-brown during tooth development. Minocycline should not be used during tooth development. Tooth development happens in the last half of pregnancy, and from birth to 8 years of age. 
  • Intestine infection (pseudomembranous colitis). Pseudomembranous colitis can happen with most antibiotics, including minocycline. Call your doctor right away if you get watery diarrhea, diarrhea that does not go away, or bloody stools.
  • Serious liver problems. Stop taking minocycline and call your doctor right away if you get any of the following symptoms of liver problems:
    • loss of appetite
    • tiredness
    • diarrhea
    • yellowing of your skin or the whites of your eyes
    • unexplained bleeding
    • confusion
    • sleepiness
  • Central nervous system effects. Central nervous system effects such as light headedness, dizziness, and a spinning feeling (vertigo) may go away during your treatment with minocycline or if treatment is stopped.
  • Benign intracranial hypertension, also called pseudotumor cerebri. This is a condition where there is high pressure in the fluid around the brain. This swelling may lead to vision changes and permanent vision loss. Stop taking minocycline and tell your doctor right away if you have blurred vision, vision loss, or unusual headaches.
  • Immune system reactions including a lupus-like syndrome, hepatitis, and inflammation of blood or lymph vessels (vasculitis). Using minocycline for a long time to treat acne may cause immune system reactions. Tell your doctor right away if you get a fever, rash, joint pain, or body weakness. Your doctor may do tests to check your blood for immune system reactions.
  • Serious rash and allergic reactions. Minocycline may cause a serious rash and allergic reactions that may affect parts of your body such as your liver, lungs, kidneys and heart. Sometimes these can lead to death. Stop taking minocycline and get medical help right away if you have any of these symptoms:
    • skin rash, hives, sores in your mouth, or your skin blisters and peels
    • swelling of your face, eyes, lips, tongue, or throat
    • trouble swallowing or breathing

Do not take minocycline if you are allergic to tetracycline-class drugs. Ask your doctor or pharmacist for a list of these medicines if you are not sure.

  • Avoid sunlight, sunlamps, and tanning beds. Minocycline can make your skin sensitive to the sun and the light from sunlamps and tanning beds. You could get severe sunburn.
  • Protect your skin while out in sunlight.
  • You should not drive or operate dangerous machinery until you know how this medication affects you. Minocycline may cause you to feel dizzy or lightheaded, or have a spinning feeling (vertigo).

Other Requirements

  • Store minocycline at room temperature between 59°F to 86°F (15°C to 30°C).
  • Keep minocycline and all medicines out of the reach of children.

What should I discuss with my healthcare provider before taking Minocin (minocycline)?

You should not take this medicine if you are allergic to minocycline or to similar antibiotics such as demeclocycline, doxycycline, or tetracycline.

If you are using minocycline to treat gonorrhea, your doctor may test you to make sure you do not also have syphilis, another sexually transmitted disease.

To make sure minocycline is safe for you, tell your doctor if you have:

  • liver disease;

  • kidney disease; or

  • asthma or sulfite allergy.

You should not use minocycline if you are pregnant. It could harm the unborn baby or cause permanent tooth discoloration later in life. Tell your doctor right away if you become pregnant during treatment.

Minocycline can make birth control pills less effective. Ask your doctor about using a non hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while using minocycline.

Minocycline passes into breast milk and may affect bone and tooth development in a nursing baby. You should not breast-feed while you are taking minocycline.

Do not give this medicine to a child without medical advice. Minocycline can cause permanent yellowing or graying of the teeth in children younger than 8 years old.

Uses For Minocin

Minocycline is used to treat pimples and red bumps (non-nodular inflammatory lesions) that occur with moderate to severe acne vulgaris in patients 12 years of age and older.

Minocycline capsules are used to treat bacterial infections in many different parts of the body. It is also used to treat anthrax infection and other infections in patients who cannot receive penicillins.

Minocycline belongs to the class of medicines known as tetracycline antibiotics. It works by killing bacteria or preventing their growth. However, this medicine will not work for colds, flu, or other virus infections.

This medicine is available only with your doctor's prescription.


Mechanism of Action

The tetracyclines are primarily bacteriostatic and are thought to exert their antimicrobial effect by the inhibition of protein synthesis. The tetracyclines, including minocycline, have a similar antimicrobial spectrum of activity against a wide range of gram-positive and gram-negative organisms. Cross-resistance of these organisms to tetracycline is common.

Antimicrobial Activity

Minocycline has been shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section:

Gram-positive Bacteria

Bacillus anthracis
Listeria monocytogenes
Staphylococcus aureus
Streptococcus pneumoniae

Gram-negative Bacteria

Bartonella bacilliformis
Brucella species
Klebsiella granulomatis
Campylobacter fetus
Francisella tularensis
Haemophilus ducreyi
Vibrio cholerae
Yersinia pestis
Acinetobacter species
Enterobacter aerogenes
Escherichia coli
Haemophilus influenzae
Klebsiella species
Neisseria gonorrhoeae1
Neisseria meningitidis1
Shigella species

Other Microorganisms

Actinomyces species
Borrelia recurrentis
Chlamydophila psittaci
Chlamydia trachomatis
Clostridium species
Entamoeba species
Fusobacterium nucleatum subspecies fusiforme
Mycobacterium marinum
Mycoplasma pneumoniae

Treponema pallidum subspecies pallidum
Treponema pallidum subspecies pertenue
Ureaplasma urealyticum

Carcinogenesis, Mutagenesis, Impairment of Fertility

Dietary administration of minocycline in long-term tumorigenicity studies in rats resulted in evidence of thyroid tumor production. Minocycline has also been found to produce thyroid hyperplasia in rats and dogs. In addition, there has been evidence of oncogenic activity in rats in studies with a related antibiotic, oxytetracycline (i.e., adrenal and pituitary tumors). Likewise, although mutagenicity studies of minocycline have not been conducted, positive results in in vitro mammalian cell assays (i.e., mouse lymphoma and Chinese hamster lung cells) have been reported for related antibiotics (tetracycline hydrochloride and oxytetracycline). Segment I (fertility and general reproduction) studies have provided evidence that minocycline impairs fertility in male rats.

Nursing Mothers

Tetracyclines are excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from the tetracyclines, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother (see WARNINGS).

Geriatric Use

Clinical studies of oral minocycline did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy (see WARNINGS and DOSAGE AND ADMINISTRATION).

Minocin Pellet-Filled Capsules (50 mg and 100 mg) do not contain sodium.


The adverse events more commonly seen in overdose are dizziness, nausea, and vomiting.

No specific antidote for minocycline is known.

In case of overdosage, discontinue medication, treat symptomatically, and institute supportive measures. Minocycline is not removed in significant quantities by hemodialysis or peritoneal dialysis.
