Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Tetracyclines may cause permanent discoloration of teeth and slow down the growth of bones. These medicines should not be given to children 8 years of age and younger unless directed by the child's doctor.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults or if they cause different side effects or problems in older people. There is no specific information comparing use of tetracyclines in the elderly with use in other age groups.

Pregnancy

Use is not recommended during the last half of pregnancy. If tetracyclines are taken during that time, they may cause the unborn infant's teeth to become discolored and may slow down the growth of the infant's teeth and bones. In addition, liver problems may occur in pregnant women, especially those receiving high doses by injection into a vein.

Breastfeeding

Use is not recommended since tetracyclines pass into breast milk. They may cause the nursing baby's teeth to become discolored and may slow down the growth of the baby's teeth and bones. They may also increase the sensitivity of nursing babies' skin to sunlight and cause fungus infections of the mouth and vagina. In addition, minocycline may cause dizziness, light-headedness, or unsteadiness in nursing babies.

Drug Interactions

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur.
