My doctor prescribed Claritin D 24hr and singular allergy

Customer Question

My doctor prescribed Claritin D 24hr and singular for my allergy and upper respiratory problem. I have taken the Alavert 6 hr and have no problem with it but for some reason this Claritin D 24 hr makes me very jittery and unable to sleep well. Thought maybe if I just took half it would be better?
JA: Thanks. Can you give me any more details about your issue?
Customer: well. keep getting upper respiratory infections and also have animal and outdoor allergies. Irritation almost constantly in in throat and nose.
JA: OK got it. Last thing — Pharmacists generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

I wouldn't suggest doing half as it is extended release. I would suggest plain claritin instead as the pseudoephedrine is what is making you jittery.

Hi there,

You can buy Claritin D 12 hours, but take it once a day in the morning. Also add liquid Benadryl 1 teaspoon at bedtime. Rest assured your allergies will be gone in no time.

Also consider Alavert aka Claritin without the D part and buy pseudoephedrine 30 mg OTC. Then take one of each in the morning.

Claritin D 24 hours has 240 mg of pseudoephedrine.
