Tetracycline passes into breast milk and may affect bone and tooth development in a nursing baby. Do not take this medication without telling your doctor if you are breast-feeding a baby.
Do not give tetracycline to a child younger than 8 years old. Tetracycline can cause permanent yellowing or graying of the teeth, and it can affect a child's growth.
Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Tetracycline can make your skin more sensitive to sunlight and sunburn may result. Use a sunscreen (minimum SPF 15) and wear protective clothing if you must be out in the sun.
Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking tetracycline. These products can make tetracycline less effective.
Throw away any unused tetracycline when it expires or when it is no longer needed. Do not take any tetracycline after the expiration date on the label has passed. Expired tetracycline can cause a dangerous syndrome resulting in damage to the kidneys.
