Help! can asthma be made better with Benadryl (diphenhydramine) ?

No: Benadryl (diphenhydramine) is not a treatment for asthma. Depending on the severity of asthma, different medications can be used. Mostly, they are inhalers since it does not cause serious side effects when you take it for a long time. You should see an allergist or pulmonologist for proper diagnosis and treatment. ...Read more

Will Benadryl (diphenhydramine) regular strength make my asthma worse?

Use with caution: The antihistamine products like benedryl will thicken your mucous secretions which can be a problem for those on the margins with asthma.

Benedryl can often be used during periods of good control, but i avoid it during flares. ...Read more

Is Benadryl (diphenhydramine) at 200mg good to take with asthma? Thanks.

Is Benadryl (diphenhydramine) at 200mg good to take with asthma?  Thanks.

Dosage?: Are you sure about the dose of 200mg? Regardless, the use of antihistamines in asthma does have a place. Often an asthmatic's "trigger" is an allergy (animal dander, dust mites, etc). Benadryl (diphenhydramine) is an excellent product but be mindful that it can make you sleepy. You may want to try a product like Claritin which mas a minimum of that kind of side effect. ...Read more

Can asthma develop with age, as in 27 years old and just now showing symptoms? And is Benadryl (diphenhydramine) bad to take if showing symptoms of asthma?

Can asthma develop with age, as in 27 years old and just now showing symptoms? And is Benadryl (diphenhydramine) bad to take if showing symptoms of asthma?

Any age: Asthma can develop at any age. Most children who develop asthma will have symptoms before 3 years old. 20% of adult onset asthma will have an occupational trigger for their asthma. Old information suggested Benadryl (diphenhydramine) and old antihistamines could worsen asthma. This is not the case, but the newer antihistamines such as claritin, zyrtec, and Allegra are effective and do have less side effects. ...Read more

Could Benadryl (diphenhydramine) help with asthma like allergy symptoms?

Could Benadryl (diphenhydramine) help with asthma like allergy symptoms?

Benadryl (diphenhydramine) is sedating: Claritin, zyrtec, allegra, or Benadryl (diphenhydramine) can help with allergy and asthma symptoms caused by allergies to respiratory pollens or other airborne allergens. One should work with his doctor to see which combination of over-the-counter allergy meds and prescription asthma inhalers/pills work the best.

Will giving Benadryl (diphenhydramine) help my 10yo with his asthma at night?  he also has allergies.

Will giving Benadryl (diphenhydramine) help my 10yo with his asthma at night?  he also has allergies.

No: Children who have asthma may have symptoms during the night, the major one being a nighttime dry cough. Benadryl(diphenhydramine) is an antihistamine which helps with allergies and can cause sleepiness. In most cases, Benadryl will not hurt the asthma but will not fix the problem. Asthma symptoms in the night are usually signs of poor asthma control and warrant follow-up with your pediatrician. ...Read more

Im asthmatic but developed a barking deep cough 4 weeks ago. Relived by ventolin and benadryl. Is the cough triggered by my asthma or something else?

Im asthmatic but developed a barking deep cough 4 weeks ago. Relived by ventolin and benadryl. Is the cough triggered by my asthma or something else?

Trigger ???: This is likely an interplay between your asthma, which is a constant but hopefully controlled,an an external trigger. Some exposure or infectious process is likely the "trigger".Sorting that out may require you keep track of when, what, where all this started and what additional symptoms you have had during the process.Take the list to you doc and see if additional treatment/s are needed. ...Read more
