• Diuretics, methoxyflurane, and other nephrotoxic medications may increase the nephrotoxic effect of tetracyclines.
• Retinoids used with doxycycline may produce an increase in benign intracranial hypertension.
• Doxycycline may increase plasma concentrations of lithium, digoxin, and theophylline.
• Anticoagulants (such as warfarin): the dose of these should be reduced, as Doxiciclina Normon 100 mg Coated Tablets influence the effect of these anticoagulants. Consult your doctor; they will indicate the appropriate dose.
• Ergotamine alkaloids and methotrexate: their toxic effect may occasionally be increased by tetracyclines.
• Ophthalmic preparations containing thimerosal: eye inflammation may occur.
• Oral contraceptives: tetracyclines may decrease their effectiveness.
• Chronic alcohol use, antiepileptics, and rifampicin may activate the metabolism of doxycycline.
