Side effect possible: Benadryl (diphenhydramine) and melatonin could make a purpose MORE tired and sleepy which could translate into being groggy in the morning thought for all practical purposes, 1 mg. Of melatonin is an extremely small amount. Then, again, I don't know anything about your build, your weight, other medications you are taking, etc. Etc. So perhaps FOR YOU....1 mg. Of melatonin is more than what it may sound. ...Read more

Can Benadryl (diphenhydramine) usage over a long term produce cause similar sexual side effects that ssris produce?

Unlikely: Ssri side effects are very well established where as antihistamine use and sexual side effects are not that well established. I would be more concerned about long term use of antihistamine and the reasons for it. Are you using it for sleep, allergy? Consult a psychiatrist as theses may be residual sx of depression and treatment may need to be optimized. ...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

Daily use of Benadryl (diphenhydramine) for sleep aid on a 16 month old. Are there long term side effects?

Nothing major: Benadryl can alter the sleep pattern some with diminished time in deep (recuperative) sleep stage. I would never consider chronic use in an infant.

What side effects come from taking 1000mg of diphenhydramine HCL daily for 8 years? And how can I stop the itching after I've stopped taking them?
