Im an epileptic pharmacist (really). Its only loratadine that has a caution, not contraindication
they also sell cetirizine very cheap on their website. its great for me asi have to take one every day.. stupid allergies
Is the loratidine because of possible interaction with carbamazepine? I think all antihistamines can have an effect on epilectics so I think you'd have to check with a GP regardless.
Loratadine and cetirizine are both 'newer' antihistamines. Both cause less drowsiness compared to piritin/chlorphenamine. I prefer cetirizine. Avoid Loratadine if you have epilepsy
