Medical and Pharmacy Editor:

DRUG INTERACTIONS: Minocycline should be used with caution with anticoagulant medications such as warfarin (Coumadin) because it increases the risk of bleeding and bruising.

Antacids containing aluminum, calcium, magnesium and iron-containing medications can bind with minocycline, delay the absorption, and reduce the effectiveness of minocycline.

Minocycline should be used with caution with oral contraceptives because it may decrease the effectiveness of oral contraceptives.

PREGNANCY: Minocycline should be avoided in pregnant women because it crosses the placenta and may cause fetal harm.

NURSING MOTHERS: Minocycline is excreted in human milk, and there is potential for serious adverse effects involving the development of teeth and bones in nursing infants. A decision should be made to discontinue medication or stop nursing, taking into account the importance of the drug to the mother.

SIDE EFFECTS: Side effects of minocycline are nausea, vomiting, diarrhea, headache, fatigue, dizziness, itching, photosensitivity, and tooth discoloration and reduced bone development in children.
