question: I am having a dizzy spell -I have a history of Menieres but have not had any spells recently. I took a meclizine strip for nausea/ vomiting but am still dizzy and wonder if I could take an antihistamine too. I also have 2 BP meds I usually take in the am --dyazide and nifedipine. My BP right now is 147/95. Should I take all my mess and should I take an Antihistamine. I have chlorpheniramine and loratadine on hand.
