Do people experience withdrawals from using diphenhydramine to get high?

I doubt it: Why take an antihistamine to get high? I have seen it precipitate seizures and it usually makes people very drousey and some children get very hyper. .. After a period of time tachyphyllaxis may occur anyway you will stop itching and the aalergies will clear up.

Are there withdrawal symptoms from diphenhydramine?

Are there withdrawal symptoms from diphenhydramine?

Benedryl side effect: No. Withdrawl symptoms are related to a body's reaction after cessation of exposure to an addictive substance. Benedryl=dyphenhydramine is not an addictive substance, so withdrawl would not be medically anticipated. You may have rebound swelling of the sinus tissues that had been treated by the antihistamine.

Due to antipsychotics withdrawal I can't sleep. If take hydroxyzine benadryl & trazodone temporarily will my sleep patterns return & need no more meds?

Due to antipsychotics withdrawal I can't sleep. If take hydroxyzine benadryl & trazodone temporarily will my sleep patterns return & need no more meds?

That's too much.: I wouldn't think it prudent to pummel yourself to sleep with all of that. If anything, maybe just 25mg of Benadryl nightly. Although it would be better in the long run if you didn't take anything - would be a lousy few days but in the end your sleep would be more natural and spontaneous.

Are there any interactions between diphenhydramine and l-theamine? Can both be taken together safely in recommended amounts for sleep?

Are there any interactions between diphenhydramine and l-theamine? Can both be taken together safely in recommended amounts for sleep?

No: I am not sure what l-theanine is. However, the only dietary supplements/herbals I know of which should be avoided when taking Diphenhydramine are valerian, st. John's wort, kava kava, and gotu kola; as the combination may enhance CNS depression. I am doubtful that whatever l-theanine is will compound any sedative effects you may experience with Diphenhydramine alone.

Does diphenhydramine have sugar in it?

Maybe...: It depends on the manufacturer of the pills you are taking. The drug itself does not contain sugar, but some manufacturers use sugars or other types of agents to 'bind' the medication--to help make it keep the shape of a pill or dissolve more slowly, for example. Ask your pharmacist about the brand you are taking, or contact the manufacturer for more information about the inert ingredients.
