Tetracycline interactions

Concomitant use of isotretinoin and tetracycline should be avoided because isotretinoin, a systemic retinoid, is also known to cause pseudotumor cerebri. (Tetracycline label, Warnings)

Drug Interactions Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracycline in conjunction with penicillin or other bactericidal antibacterials. (Tetracycline label, Drug interactions)

Because the tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. (Tetracycline label, Drug interactions)

• Tetracycline may reduce atovaquone concentrations; parasitemia should be closely monitored. (Atovaquone and proguanil label, Drug interactions)

Calcium binds these drugs in the gut and can sharply cut how much is absorbed; separate the doses. (NIH Office of Dietary Supplements, Calcium)

Drug Interactions Cholestyramine for Oral Suspension USP may delay or reduce the absorption of concomitant oral medication such as phenylbutazone, warfarin, thiazide diuretics (acidic), or propranolol (basic), as well as tetracycline, penicillin G, phenobarbital, thyroid and thyroxine preparations, estrogens and progestins, and digitalis. (Cholestyramine label, Drug interactions)

Iron binds these drugs in the gut and reduces their absorption; separate the doses. (NIH Office of Dietary Supplements, Iron)

Magnesium-containing supplements and antacids reduce absorption of these drugs; separate the doses by at least two hours. (NIH Office of Dietary Supplements, Magnesium)

Tetracycline and other drugs that interact with magnesium Simultaneous administration of tetracycline with quinapril hydrochloride reduced the absorption of tetracycline by approximately 28% to 37%, possibly due to the high magnesium content in quinapril tablets. (Quinapril label, Drug interactions)

Because the tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. (Tetracycline label, Drug interactions)

Drug Interactions Some studies have shown that simultaneous sucralfate administration in healthy volunteers reduced the extent of absorption (bioavailability) of single doses of the following: cimetidine, digoxin, fluoroquinolone antibiotics, ketoconazole, l-thyroxine, phenytoin, quinidine, ranitidine, tetracycline, and theophylline. (Sucralfate label, Drug interactions)

Because the tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. (Tetracycline label, Drug interactions)

Zinc reduces absorption of quinolone and tetracycline antibiotics; take the antibiotic at least two hours before or four to six hours after zinc. (NIH Office of Dietary Supplements, Zinc)

Absorption of tetracyclines is impaired by antacids containing aluminum, calcium or magnesium and preparations containing iron, zinc, or sodium bicarbonate. (Tetracycline label, Drug interactions)
