Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Bacterial resistance: Misuse of an antibiotic such as doxycycline may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better when you first start taking doxycycline, you need to continue taking the medication exactly as directed to finish ridding your body of the infection and to prevent resistant bacteria from taking hold. Do not take doxycycline or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Birth control pills: When you use birth control pills at the same time as minocycline, they may be less effective, and you may experience an increased risk of breakthrough bleeding. Your doctor may advise that you use a second form of birth control while taking this medication.
Diarrhea: Minocycline may infrequently cause a condition called pseudomembranous colitis (serious diarrhea caused by antibiotics). If you develop severe diarrhea after starting this medication, even several weeks after treatment, contact your doctor as soon as possible.
Discolouration of teeth: The use of minocycline during tooth development (from the last trimester of pregnancy to the age of 13 years) may cause permanent discolouration of the teeth (yellow-grey-brown). Though more commonly associated with long-term use of tetracyclines, this effect has also been known to occur after taking the medication for a short time. For this reason, minocycline should not be used by children 13 years old or younger unless other medications are unlikely to be effective or can’t be used.
Drowsiness/reduced alertness: People who take minocycline may experience headaches, lightheadedness, dizziness, or loss of balance. Decreased hearing has been reported rarely by those who take this medication. These symptoms may disappear during therapy and usually disappear rapidly when the medication is stopped. Avoid activities requiring alertness, such as driving vehicles or using hazardous machinery if the medication affects you in this way.
Galactose intolerance/glucose malabsorption: Some brands of minocycline contain lactose. If you have lactose or galactose intolerance you should not take these medications.
Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: Minocycline may reduce liver function and can cause liver failure. If you have liver problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Medical conditions: If you have autoimmune disease or lupus, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Overgrowth of organisms: The use of antibiotics may occasionally result in an overgrowth of organisms not killed by medication. This can cause conditions such as yeast infections to occur. You may be able to prevent yeast infections by eating yogurt daily while taking minocycline.
Sun sensitivity: An exaggerated sunburn reaction may occur for some people taking minocycline. If skin redness appears, stop taking the medication and check with your doctor.
Pregnancy: This medication should not be used during pregnancy. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and are taking minocycline, it may affect your baby. Do not breast-feed while taking this medication.
Children: Minocycline is not recommended for use by children younger than 13 years of age.
