How many Benadryl (diphenhydramine) allergy pills do I take?

How many Benadryl (diphenhydramine) allergy pills do I take?

Perhaps, one: See prior answer for details about benadryl (diphenhydramine). An over the counter dose is 25 mg (the same dose they put in many 'sleep aides' like tylenol-pm, where the side effect of Benadryl (diphenhydramine) of drowsiness is the main ingredient). If taking it for typical allergies (runny nose, watery eyes, sneezing), could try one tablet. But there are better ones today with less side effects (zyrtec, allegra, claritin, etc). ...Read more

Can I take Benadryl (diphenhydramine) allergy pills to sleep?

Can I take Benadryl (diphenhydramine) allergy pills to sleep?

Yes: Benadryl (diphenhydramine) (diphenyhydramine) and other similar medication (doxylamine) are the ingredients in many (if not most) over the counter sleep aids. They are antihistamines (allergy meds) that have a side effect of sleepiness. It's not recommended to take them regularly as they are not a cure for insomnia and because they can lead to daytime drowsiness. 2 weeks is the maximum. Do not mix with alcohol. ...Read more

I recently have been prescribed xanax. I took 1 pill .25 at 11am. Is it safe to take a Benadryl (diphenhydramine) now at 10:04pm?? My allergies are bugging me.

I recently have been prescribed xanax. I took 1 pill .25 at 11am. Is it safe to take a Benadryl (diphenhydramine) now at 10:04pm?? My allergies are bugging me.

Yes: It is almost 12hrs since you last xanax dose. The effect of xanax is usually much shorter than 12hrs, so it is safe to take benadryl (diphenhydramine). You may want to consider non-sedating antihistamine, like zyrtec, claritin, or allegra, which are generally safe to use with anti-anxiety medications. ...Read more

Penicillin allergy, after 8 pills: got hives, especially fastidious on the gluteus (3 days). I started Benadryl (diphenhydramine) yesterday. How long will hives last?

Hard to say: Take the Benadryl (diphenhydramine) regularly as your dr. Prescribed...It could take several days to go away....But as long as there is no significant swelling(unlikely to occur now..I presume you stopped the penicillin) there should be nothing to worry about.... ...Read more
