2 hours to limit an interaction.
Calcium; Vitamin D: Antacids may inhibit the oral absorption of antimuscarinics. Simultaneous oral administration should be avoided when feasible; separate dosing by at least 2 hours to limit an interaction.
Carbetapentane; Chlorpheniramine: Drowsiness has been reported during administration of carbetapentane. An enhanced CNS depressant effect may occur when carbetapentane is combined with other CNS depressants including anticholinergics. The anticholinergic effects of sedating H1-blockers may be enhanced when combined with other antimuscarinics. Clinicians should note that anticholinergic effects might be seen not only on GI smooth muscle, but also on bladder function, the eye, and temperature regulation. Additive drowsiness may also occur when antimuscarinics are combined with sedating antihistamines.
Carbetapentane; Chlorpheniramine; Phenylephrine: Atropine blocks the vagal reflex bradycardia caused by sympathomimetic agents, such as phenylephrine, and increases its pressor effect. Drowsiness has been reported during administration of carbetapentane. An enhanced CNS depressant effect may occur when carbetapentane is combined with other CNS depressants including anticholinergics. The anticholinergic effects of sedating H1-blockers may be enhanced when combined with other antimuscarinics. Clinicians should note that anticholinergic effects might be seen not only on GI smooth muscle, but also on bladder function, the eye, and temperature regulation. Additive drowsiness may also occur when antimuscarinics are combined with sedating antihistamines.
Carbetapentane; Diphenhydramine; Phenylephrine: Atropine blocks the vagal reflex bradycardia caused by sympathomimetic agents, such as phenylephrine, and increases its pressor effect. Drowsiness has been reported during administration of carbetapentane.
