Brief Answer:
Maximun 2 days.

Detailed Answer:
Hi,

I went through the query and understood your concern.

The active content in zzzquil is diphenhydramine whose elimination half live varies and hence complete elimination of the drug from the body takes around 36 hours to 45 hours (up to 2 days) maximum. But its effects will start reducing after4-5 hours.

I hope this information helps you and answered your question. Feel free to ask for any further queries. I will be glad to answer them.

Wish you good health.
Regards

about 1/2 hr to an hr after eating dinner which were food items I've eaten many times before fresh lemon, dried rosemary herb, ate before dinner- trail mix, chocolate after dinner an itching began on abdomen, bumsp appeared then itching behind my ears, upper back, under cheeks of buttocks, under chin, near right eye. Pharmacist suggested an allergy medication (diphenhydramine & antihistamine) which I took 2 last night and it seemed to have worked but awoke this morning and itching started up again but this time it was my underside of wrist, bottom of the palm of hand just above the wrist, behind knee, groin area, elbows, bend of arm, my bottom lip seemed puffy. I took one pill around 6:30am because I didn't want to get sleepy again and it has subsided. At what point should I see a doctor? How long does the food induced hives last after eating and then treating with medicine, in other words, will this continue all day? Since I only took 1 allergy pill this morning can I take another one 2 hrs later, not to exceed 6 times in 24 hrs? Recommended dosage on pkg is 1-2 pills every 4-6 hrs.

My son has a raised rash on the backs of each hand and elbows, which he has had since yesterday. He has had a similar rash many times before when playing in grass. He has been playing soccer on grass turf all week. My husband gave him one loratadine (active ingredient - 10 mg) tablet 2 hours ago because he could not find benedryl (diphenhydramine hydrochloride) at the time. I have the benedryl, can he take some now (2-4 tablets - 12.5 mg). If yes, how much? If no, when can he take benedryl.

I have been told by a doctor that my 2month old baby has extrapyramidal symptoms (EPS), but after reading about what this is, I cannot believe that she has this. He looked at her and told me that the fact that she is lifting her head up quite high for her age, that she has these symptoms. She used a colic mixture which contains Diphenhydramine and he told us to stop with this mixture. However, after reading about EPS, everyone suggests Diphenhydramine as a treatment for EPS. Please help. How does a doctor establish whether a 2 month old baby has EPS?
