How does Claritin-D interact with other medications or food?

Claritin-D (12-hour or 24-hour) may interact with a variety of medications. However, Claritin-D has been used in combination with erythromycin, cimetidine and ketoconazole in controlled clinical pharmacology studies. Loratadine and pseudoephedrine should not be taken with MAOIs (monoamine oxidase inhibitors) and for two weeks after stopping the use of an MAOIs. The antihypertensive effects of beta-adrenergic blocking agents, methyldopa, mecamylamine, reserpine and veratrum alkaloids, may be reduced by sympathomimetics. There is evidence that there may be increased ectopic pacemaker activity when pseudoephedrine is used concurrently with digitalis. Do not use this with any other over-the-counter cold, allergy or sleep medication without first speaking to your doctor or pharmacist, since it may result in an overdose of the medications' ingredients. Do not drink alcohol while taking this medication. Do not use this with any pain medications, diuretics, muscle relaxers, blood pressure medicine, bladder or urinary tract medications, beta blockers, antidepressants and even certain aspirins. No particular food interactions are known.
