? sa: I am going to assume "sa" is seasonal allergies. So, yes, Benadryl (diphenhydramine) would work for these, but is certainly not the optimal answer. Benadryl (diphenhydramine) tends to be sedating and also needs to be taken 4 times a day for optimal effect. If you are having to take doses that often to keep symptoms under control, should consider alternative treatment for allergies. If "sa" not allergies, please resubmit question. ...Read more
Time For DroolSchool: We here on the ranch call it"Benadrool"because it can shlog you out. So yes sometimes it can work for calming down. But too much turns it into Bena-DryMouthBlurredVisionKnockedOut-Dryl. So just take one capsule (25mg)or at most 50mg. It's not usually prescribed for this. There are other medications specifically for anxiety. But Benadryl (diphenhydramine) is a non-prescription medication and usually safe at proper doses ...Read more

How does hydrocodone cream works? How can my hubby be alergic to benadryl (diphenhydramine) but not hydrocodone? Aren't they the same thing?
Totally different: Benadryl (diphenhydramine) is an antihistamine and hydrocodone is an analgesic. Benadryl (diphenhydramine) works for allergic diseases, hydrocodone works for certain pain. However I believe you meant hydrocortisone cream which works for allergic skin lesions (contact dermatitis) since I am unaware of the availability of a hydrocodone cream. ...Read more

Have fun with the dogs, I hope you will develop tolerance. ...Read more

My allergies are worse in the spring. Benadryl (diphenhydramine) works better than Rx but makes me sleepy. Is there anything else that could help?
Allergies are worse:
There are other options to treat your Allergic Rhinitis, and Benadryl (diphenhydramine) is more for allergic reactions to foods, bites, chemicals.
OTC antihistamines such as Zyrtec, Claritin do better for your allergies, and there are nasal sprays with steroids such as Flonase, Nasacort work well without sedative effects.
Singular helps people with asthma+ for many with seasonal allergic rhinitis also. ...Read more
Is it okay to mix ambien and benadyrl to treat insomnia? I took benadryl (diphenhydramine) around 4hrs after taking ambien bc it didn't work, are there side effects?
No don't mix drugs: Please don't mix ambien with benadryl (diphenhydramine). I would first suggest you speak with your doctor who prescribed you ambien and him/her that you are still experiencing insomnia. Mixing prescription medication with drugs like benadryl (diphenhydramine) can be dangerous. Perhaps you should improve your sleep hygiene first. Sleep same time every night, bed is used only for sleep, cool dark room, no distractions (TV) etc. ...Read more
