Drug-drug. Adsorbent antidiarrheals: decreased minocycline absorption
Antacids containing aluminum, calcium, or magnesium; calcium, iron, and magnesium supplements; sodium bicarbonate: decreased minocycline absorption
Cholestyramine, colestipol: decreased oral absorption of minocycline
Hormonal contraceptives: decreased contraceptive efficacy
Penicillin: interference with bactericidal action of penicillin
Sucralfate: blocked absorption of minocycline
Warfarin: increased anticoagulant effect
Drug-diagnostic tests. Alanine aminotransferase, alkaline phosphatase, amylase, aspartate aminotransferase, bilirubin, blood urea nitrogen: increased levels
Hemoglobin, platelets, neutrophils, white blood cells: decreased levels
Urinary catecholamines: false elevation
Drug-food. Dairy products: decreased minocycline absorption
Drug-behaviors. Alcohol use: decreased antibiotic effect
Sun exposure: increased risk of photosensitivity reaction
• Assess patient's oral health closely for dental problems.
• Monitor patient for superinfection, especially oral, bladder, and vaginal yeast infections.
• Evaluate CBC and renal and liver function tests frequently.
