Not typically. Benedryl helps by blocking histamine, so it is most useful for allergic problems like runny nose. It also is an effective sleep aid. It does not help much with asthma despite the fact that asthma is often allergy related. This is because of the inflammatory nature of asthma.
NO. Benadry is an antihistamine, that has anti-allergy properties, but also anticholinergic properties that can make you drowsy, can dry secretions, in older males--can cause difficulty urinating due to bladder outlet constriction. If you are having an anaphylactic reaction, let's say to a bee sting, then the bronchial tubes will constrict and Benadryl (diphenhydramine) can help; but by then u need an epi shot.
Maybe. If cause of breathing difficulty is allergic in origin, Benadryl (diphenhydramine) may help since it's an anti-allergy medication.
Yes but. Benadryl (diphenhydramine) does cause sleepiness, and is found in many over-the-counter sleeping pills. Used here and there, now and then, it is fine for many but not all people. If used regularly, it loses its ability to improve sleep. It does cause daytime sleepiness into the next day.
Most definitely.. ..Esp. If you tend to suffer from other "atopic" problems such as seasonal allergies, hayfever, congestion, eczema, mild asthma, sensitive stomach, itching, frequent headaches late in the day, etc. Did you have tonsils removed, frequent ear infections as a child, or recurrent sinus problems? Then very likely it will help you. Those are very likely related the the reasons you can't get to sleep.
Perhaps, one. See prior answer for details about benadryl (diphenhydramine). An over the counter dose is 25 mg (the same dose they put in many 'sleep aides' like tylenol-pm, where the side effect of Benadryl (diphenhydramine) of drowsiness is the main ingredient). If taking it for typical allergies (runny nose, watery eyes, sneezing), could try one tablet. But there are better ones today with less side effects (zyrtec, allegra, claritin, etc).
A long time. The half life is 8 hours. Assuming that after 4 half lives it is eassentially gone it would take upwards of 32 hours to be eliminated.
Yes. Benadryl (diphenhydramine) (diphenyhydramine) and other similar medication (doxylamine) are the ingredients in many (if not most) over the counter sleep aids. They are antihistamines (allergy meds) that have a side effect of sleepiness. It's not recommended to take them regularly as they are not a cure for insomnia and because they can lead to daytime drowsiness. 2 weeks is the maximum. Do not mix with alcohol.
Yes. A 28 year old female would like to know if it is safe to take "benadryl (diphenhydramine) and pretnizone together." I am assuming you mean prednisone. Prednisone is a an oral steroid and benadryl (diphenhydramine) is an anthistamine. They have different effects and are safe to take together. However, remember that benadryl (diphenhydramine) can make you sleepy.
1-2 every 4-6 hrs. Benadryl (diphenhydramine) is an antihistamine used in the treatment of allergies. It doesn't work long so it has to be taken often. The recommended dose is 1 or 2 pills (each 25 mg) every 4-6 hours, so a maximum of 12 per day (300 mg/day). Taking any Benadryl can cause sleepiness, headaches, dry mouth, & difficulty urinating. Excess Benadryl can cause delirium, diarrhea, seizures, and even coma.
Depends. Follow the directions on the bottle unless you have spoken with your physician who gave you a different instruction list. The maximum recommended daily dose (not all at once) is 300mg/day.
Benadryl (diphenhydramine) makes me drowsy. If I take the recommended dose of Benadryl (diphenhydramine) allergy ultratabs (25mg) for my flight will that be okay?
Are you the pilot? Make sure you tell the flight attendant to wake you up if you are flying and need top switch planes. Don't take Benadryl (diphenhydramine) if you are planning on driving or piloting a plane if it makes you sleepy.
Toxicity. It will have toxic side effects.
