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:
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.

Take this medicine with a full glass of water.
You may take minocycline with or without food.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Minocycline will not treat a viral infection such as the flu or a common cold.
If you use this medicine long-term, you may need frequent medical tests.
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using minocycline.

Throw away any minocycline not used before the expiration date on the medicine label. Using expired minocycline can cause damage to your kidneys.

Take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What should I avoid while taking Dynacin (minocycline)?
This medicine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.
Avoid exposure to sunlight or tanning beds. Minocycline can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.
For 2 hours before or after you take minocycline, avoid taking antacids, laxatives, multivitamins, or supplements that contain calcium or iron. These other medicines can make it harder for your body to absorb minocycline.
