What are the drug interactions for allergy medications?
Before starting any medication, let your doctor know your full medical history such as drug allergies, medical conditions, current medication use, and whether you are pregnant, trying to get pregnant, or nursing.
Antihistamines may interact with other drugs that cause drowsiness, such as sleeping medications, narcotic pain medications, sedatives, anticholinergics, muscle relaxants, antidepressants, seizure medications, or other medications used for allergies or colds.
Corticosteroids may interact with drugs affecting metabolism of corticosteroids, such as ketoconazole (Nizoral, Xolegel, Extina, Ketoconazole Cream) and ritonavir (Kaletra Capsules, Kaletra Tablets, Norvir).
Leukotriene inhibitors may interact with drugs that stimulate liver metabolism, such as phenytoin (Dilantin, Dilantin 125, Dilantin Infatabs, Dilantin Kapseals) phenobarbital, and carbamazepine (Tegretol, Carbatrol, Equetro) and with rifamycin antibiotics.
Oral decongestants may interact with antidepressants, cold or allergy medications, migraine medications, blood pressure medications, and other decongestants.
Among topical immunomodulators (Elidel and Protopic), there may be drug interaction with certain antibiotics, antifungals, calcium channel blockers, and cimetidine (Tagamet). Pregnant or nursing women should discuss them with their doctors prior to use.
