Is it okay to mix Benadryl (diphenhydramine) with my other medications?

Is it okay to mix Benadryl (diphenhydramine) with my other medications?

Avoid these: Older antihistamines like Benadryl (diphenhydramine) interact with many drugs. Don't mix it with alcohol, sleeping pills, sedatives, antidepressants, potassium supplements, sodium or potassium phosphate, antipsychotics, MAO inhibitors, symlin (pramlintide), sodium oxybate, Precedex (dexmedetomidine) & abilify (aripiprazole). Loratidine and fexofenadine are as effective & much safer. Discuss this with your doctor. ...Read more

I have red patches all over my body they itch. I went to the hospital and the gave me benadryl, (diphenhydramine) prednisone, &cimetidine these medications did nothing!?

I have red patches all over my body they itch. I went to the hospital and the gave me benadryl, (diphenhydramine) prednisone, &cimetidine these medications did nothing!?

Foolish: ER people treat heart attacks, accidents, emergencies. That's why we call it the emergency room. They are poor at treating "red patches all over". What did they call it? Stop this foolishness and see a dermatologist. When you call, indicate if it is urgent. Is your water safe yet? Do not take Benadryl (diphenhydramine) except bedtime. It is a sleeping pill. Cimetidine is for acid stomach, not for skin. You need a p ...Read more

I ingested an allergen 5 days ago. I am still having a reaction and Benadryl (diphenhydramine) is the only drug working well. At 190 lbs how much can I take safely?

Unusual: Unless it was a drug, the allergic reaction does not usually lasts this long. As for Benadryl, (diphenhydramine) the dose is more dependent on its side effects than weight. Most people should be able to tolerate up to 50 mg 4x daily (except those ...Read more

If I become resistant to effects of diphenhydramine drowsiness, can I switch to doxylamine, or am I resistant to that too since they're similar drugs?

If I become resistant to effects of diphenhydramine drowsiness, can I switch to doxylamine, or am I resistant to that too since they're similar drugs?

You can switch.: They are different drugs so I would suspect you will be sedated by the doxylamine in spite of prior Benadryl (diphenhydramine) use. Best wishes. ...Read more

Is there a home drug test to test for diphenhydramine o.t.c. abuse? I suspect my husband is abusing it

Very doubtful: There's info here: https://en. Wikipedia. Org/wiki/Diphenhydramine
But, I'm concerned too about your relationship. Suspicion is often as harmful as the behavior in question. Consider Couple's Therapy after a few prep sessions for you alone to learn how to communicate concern w/o blame. A test would do nothing to help resolve any problem. Best wishes 2U2. ...Read more

I'm on drug court and I want to take a sleep aid because I can't sleep I have a generic sleep aid but it has diphenhydramine hci in it will this make me test positive for anything or will it be ok to take it

I'm on drug court and I want to take a sleep aid because I can't sleep I have a generic sleep aid but it has diphenhydramine hci in it will this make me test positive for anything or will it be ok to take it

The: The answer dr. Johnson provided is correct. There are reports that with very high doses, Diphenhydramine has in rare cases, led to false positive drug screening for benzodiazapines. However, if this were to occur, normally the sample would be retested using a more precise test and that would clear up the confusion. It is reported that it could also trigger a false positive for pcp (but this is also very rare).
Diphenhydramine is not a good choice for chronic problems with sleep. If you are in a program that requires drug testing, you might consider skipping the Diphenhydramine and working on sleep hygiene first. ...Read more

Can taking a tablet of xyzal help to blunt an allergic reaction to a drug as fast & effectively as Benadryl (diphenhydramine) would?

Can taking a tablet of xyzal help to blunt an allergic reaction to a drug as fast & effectively as Benadryl (diphenhydramine) would?

Possibly: You don't describe what kind of a reaction and what drug you are asking about. Depending on the medication and reaction, medications other than anti-histamines may be necessary. If you are asking about an itchy rash, odds are that the 2 medications may be equvally effective. ...Read more
