Question 1

safe to take 1 tablet of benedryl (25 mg active ingredient) with two tablets of nyquil severe?

Accepted Answer

Not safe: I do not suggest taking these drugs together. Benadryl is an antihistamine. The Doxylamine succinate in NyQuil Severe is also an antihistamine. NyQuil Severe delivers maximum symptom-fighting ingredients and so taking another similar drug is too much and could accentuate possible side effects. I also suggest an routine exam at a medical clinic for your condition.

Question 2

is it possible for someone to have anaphylactic shock from the active ingredient in benadryl (diphenhydramine)?

Accepted Answer

Yes you can: It is possible to get an allergic  reaction including anaphylaxsis from anything.

Question 3

is this possible?: a persons body makes antibodies against the active ingredient of generic diphenhydramine, but it does not make antibodies against the active ingredient of brand benadryl?

Accepted Answer

Not possible: This isn't possible. The active ingredient is diphenhydramine, the same in both generics and the Benadryl brand.

Question 4

i take at least 200mg of the active ingredient in benadryl (diphenhydramine) and or sleep aids every day. at the same time.to make me sleep.is it dangerous?

Accepted Answer

Yes!: Not being able to sleep  may indicated sleep problems that can be life shortening or life threatening. The only way to know if there are serious problems is with an overnight sleep test. I encourage you to seek help.

Question 5

will taking benadryl (diphenhydramine) allergy when on birth control null the active ingredients in the birth control?

Accepted Answer

No: There is no interaction between Benadryl (diphenhydramine) and birth control tablets, unless Benadryl (diphenhydramine) makes you too sleepy and you forget to take the birth control tablets...

Question 6

if benadryl's plasma clearance is about 9 hours x 5, how long would it remain active to affect the brain and interact with other medications?

Accepted Answer

Less than 12 hrs: It may take a long time for a drug to completely clear from the body, the biochemical effect occurs only with a certain blood level.  I have yet seen anyone getting drowsy from Benadryl (diphenhydramine) for more than 12 hours. It is the drug level that matters.

Question 7

if benadryl (diphenhydramine) has same ingredient as unisom why the diff. names. ?

Accepted Answer

Trade names are diff: Medicines by different manufacturers have different names, even if the active ingredient is the same.  Bendaryl's active ingredient is diphenhydramine.

Question 8

please let me know if there is anything that contains the same ingredients that benadryl (diphenhydramine) has but its non drowsy?

Accepted Answer

Antihistamine: Benadryl (diphenhydramine) is the first generation antihistamine that has anticholinergic property and crosses the blood-brain barrier causing drowsiness. Several other second generation antihistamine works well and does not cause drowsiness like zyrtec, allergra and claritin.

Question 9

will benedryl help dry mucus?

Accepted Answer

Possibly: Benadryl (diphenhydramine)  is a sedating antihistamine.  The best answer i can give you is if the mucus production is caused by an allergic rhinitis (allergy of the nose) Benadryl (diphenhydramine) will help.  However, if the mucus production is not of an allergic etiology, the antihistamines will be of little help and an otc decongestant will be more helpful for symptomatic relief.

Question 10

does benedryl contain alcohol?

Accepted Answer

No: Benadryl is diphenhydramine, an anticholinergic antihistamine over-the-counter medication used for allergies. It can be sedating and is found in sleep aids for this reason. It does not contain alcohol.
