can you take benadryl as a sleep aide while prescribed methadone

my son had shortness of breathe and I was wondering if taking 2 (25mg each) of benadryl as a sleep aide with his prescribed methadone (70mg) per day could be the cause?? ## You son needs to consult his doctor to have this checked out and be certain of the cause. While it may have been due to taking the Benadryl with the Methadone, since they both cause depression of the central nervous system, there is also a chance that it may have been due to an unrelated health issue. Is there anything else I can help with? ## There could very well be an underlying cause as to why your son had or has shortness of breath. However, you must be cautious about giving someone anything containing alcohol or small dosages codeine. Those will have an affect on anyone's breathing while taking a strong nar...

Hot pink pill B imprint

Please help! I've found a hot pink round pill w/ an imprint of B. Nothing else. I found it in my daughters things after unpacking from a trip. ## It is identified as Fastmelt Children's Benadryl 19mgs. She had allergy problems I'm guessing. :) ## Yes, Benadryl contains the active ingredient Diphenhydramine, it is used to treat allergies, and as a sleep aid, since it causes drowsiness as a side effect, along with dizziness, and dry mouth. There is a round, pink childrens tablet with a B on it, as described by Jimbo, as well as a regular 25mg oblong pink tablet, both are available over the counter. Is there anything I can help with?

Banging into anything is causing extreme itching

I figured I'd come here hoping anyone can figure out this weird thing happening with my dad, we cannot figure out. Everytime he hits his body off something (example: getting up from the couch and he hits his leg off the coffee table. Just normal terrible luck kind of hits where u smack ur arm or leg off something lol), it'll cause suucchh a baadd itch that he can't get to stop unless he takes some Benadryl :/ it's thee weirdest thing. If he cuts himself it doesn't happen, it's literally just when he hits a body part off something like we allll do. His dr said maayybbee it could be a blood disorder? :/ but i just don't know. He's relying on Benadryl almost everyday because if he bumps into anything hard enough it'll cause such extreme itching. Does ANY...

pediatric drug dosing

child wt. 10 kg How much Benadryl can I give>> ## can we use trace elements alone without TPN in pediatric patients? if yes, how can we administer it? ## Hello, Here are the suggested dosage instructions from the Benadryl website. Children under 4 years: Do not use Children 4 to 5 years: Do not use unless directed by a doctor Children 6 to 11 years: 5mL Adults and children 12 years and over: 10mL According to the kids data organization the average 2 year old weighs 12kg so I am going to make the assumption that your child is likely less than 4 years old and with that in mind I suggest that you do not give your child any Benadryl. If your child is having symptoms you believe require Benadryl please consult your pediatrician for the options that would work best for you and your ch...

benadryl and bromfed interactions

Can I take benadryl and bromfed within a couple hours of each other? I have a terrible cough. Took benadryl first and it hasn't helped. ## Benadryl is an antihistamine that is used to treat or prevent allergic reactions, so it will not do anything to treat a cough, and unfortunately, Bromfed also isn't like to help, since it has not cough suppressant properties, according to the NIH. To treat a cough, you need a cough suppressant. Have you consulted your doctor to see what's causing your cough and what would be the best remedy? Are you on any other medications? ## I took benadryl two hrs ago but now have a very bad headache. Can I take a BC powder? ## I took benadryl for allergy issues, and 30 mins to an hour later I took a BC powder for a headache. Can this affect me?

Bad reaction after switching from Subutex to Suboxone

I was on Subutex for over a year and a half then I lost my doctor. When I found out I was pregnant he put me back on subutex. After I had my daughter he took me off subutex and put me on suboxone. Within a couple hours of the first dose my skin became red and blotchy. I couldn't stop scratching at myself so he prescribed Benadryl for an allergic reaction... I continued to take them for a month and a half.. I started getting horrible migraines and nausea, and now within an hour hour and a half of taking the pill I'll throw up.... Every time. I have spoken with my doctor about these symptoms..He tells me its not physically possible to be allergic to Suboxone and that if I'm allergic to it then I must be allergic to Subutex as well. But I never had these issues with the Subutex...
