Is antihistamine bad for asthma. If not what is the safest antihistamine to take with minimum side effects?

Is antihistamine bad for asthma. If not what is the safest antihistamine to take with minimum side effects?

No: Antihistamines are not bad to take if you have asthma, however if you're using them to treat asthma symptoms this is not appropriate. Antihistamines are for itchy, sneezy symptoms secondary to allergies. Asthma medications include albuterol and daily inhaled steroids. Non-sedating antihistamines like Claritn, Zyrtec, and Allegra (fexofenadine) have relatively equal efficacy and safety profiles ...Read more

I have mild asthma and take antihistamines year round, I've stopped taking them unless needed but my asthma has flared up, are they connected?

I have mild asthma and take antihistamines year round, I've stopped taking them unless needed but my asthma has flared up, are they connected?

Yes: Asthma is allergy of the lung, so taking an anti-histamine will help alleviate some of the symptoms of asthma but not all ; for moderate to severe cases of asthma, just taking an anti-histamine could be very dangerous. If you have asthma year around, you probably need to be on a steroid type inhaler or a longer acting medication such as singular. I suggest seeing a doctor, get lung function test. ...Read more

Allergic asthma: Antihistamines and singulair (montelukast) won't control your asthma, you need more prescription medications, mainly inhaled corticosteroids and bronchodilators, more important though is to get evaluated right for better management, you might other conditions that make your asthma worse, like chronic sinusitis or reflux, you may be a candidate for allergy shots, check aaaai.

I have asthma...usually is triggered by dust. Antihistamine help a little but it is good idea to take allergy shots and where can get the shots?

Bronchodylators: Better to use inhaled bronchodylators (beta 2 agonists) and anti-inflammatory meds (steroids). Allergy shots do not work very well for asthma. An internal medicine doctor should be able to take care of your problem. ...Read more

I had childhood asthma no probs for 10 years had an asthma attack 2 weeks ago still worsening peak flow is <100 what to do steroid antihistamine used?

Steroids/albuterol: I would suggest that you use inhaled albuterol and some form of steroid preparation for your symptoms.
Based on your recent history of an asthma attack and low peak flow, you should seek medical care to determine whether you need to be admitted to the hospital. If they can manage you as an outpatient, determining the dose of the steroid and whether it is in an inhaled or oral form is suggested. ...Read more

Would it be possible that a pregnant woman take benadryl/antihistamine to treat an allergic reaction or help allergy induced asthma?

Would it be possible that a pregnant woman take benadryl/antihistamine to treat an allergic reaction or help allergy induced asthma?

Yes & No: Benadryl (diphenhydramine) is considered safe in pregnancy & may be used to treat allergic conditions like allergic rhinitis or hives. Antihistamines like Benadryl are not effective for itching not associated with a rash. This can be due to pregnancy-related liver problems. Talk to your OB about that. Benadryl is also not effective for asthma. There are safe asthma drugs to use while pregnant. ...Read more

Does anticholinergic or antihistamine alone relieve bronchoconstriction in asthma? Will doctors prescribe one or another or both with beta 2 agonist?

Does anticholinergic or antihistamine alone relieve bronchoconstriction in asthma? Will doctors prescribe one or another or both with beta 2 agonist?

Anticholinergic: Anticholinergic but not the usual doses of antihistamine relieves bronchoconstriction in some people. It may be used as a combination with a beta 2 agonist as in the case of combivent (albuterol and ipratropium). However persistent asthma should be treated with a controller drug such as inhaled steroid and/or a leukotriene blocker. Using just beta agonist alone on a regular basis may actually make your asthma worse. ...Read more

I have asthma & severe allergies, currently taking zyrtec, singulair (montelukast) and albuterol as needed. We are trying to conceive & I know antihistamines dry up mucus, what can I do to help my mucus in uterus?

I have asthma & severe allergies, currently taking zyrtec, singulair (montelukast) and albuterol as needed. We are trying to conceive & I know antihistamines dry up mucus, what can I do to help my mucus in uterus?

Complicated: Antihistamines can all interfere with ovulation by blocking the action of histamine, a chemical that also plays a role in releasing an egg from the ovary and implanting it in the womb. These drugs are effective at relieving the symptoms of an allergic reaction, but they may also halt conception. If you’re trying to get pregnant, it’s best to avoid antihistamines from mid-cycle until your period. ...Read more

Asthma guidelines: If you do have asthma spireva is not an asthma medication, although is sometimes of benefit especially if there is also copd. I cannot tell you what is the correct asthma medication for you. You need to see a board certified allergist for appropriate evaluation and treatment of your entire respiratory system. ...Read more

Both of those: Medications are not contraindicated in asthma. Benadryl (diphenhydramine) is not contraindicated in asthma. Many asthmatics have allergies which are treated with antihistamines of which benadryl (diphenhydramine) is the gold standard. ...Read more

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. Asthma patients tend to have problems with excess secretions already & thickening them lakes it harder for them to be cleared from the airways. 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.

Depends on situation: Antihistamines have a drying effect & can cause a thickening of the respiratory mucous that is already a problem for some asthmatics. When asthma is well controlled & the occasional allergic issue arises, I see no problem using benedryl. I don't recommend it to those that are symptomatic with their asthma. ...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. A patient will learn over time, what medicines to add or increase, depending on how "bad" the air is. ...Read more

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

I have really bad allergies & also asthmatic, I am wondering if it is safe to take Benadryl (diphenhydramine) as my allergies are unbareable, will it affect my asthma?

Better to use Clarit: Benadryl (diphenhydramine) or diphenylhydramine is a first generation antihistamine wich is quite sedating and has to be taken every 4to6 hours to be effective, while Claritin is long actong once a day, non sedating and can be taken with all other asthma meds. ...Read more

I have asthma, allergies and pnd. I believe Benadryl (diphenhydramine) will curb my pnd, yet may harm asthma. Should I use it here and there at regular strength? Thank

Maybe maybe not: Often asthmatics do use antihistamines in cinjunctinwith their routine asthma meds. Discuss using a non-sedating antihistamine like Claritin with your phsyician. Have you tried nasal saline which does not affect your asthma and may reduce your pnd. ...Read more

I'm 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?

I'm 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

I wanted to know I took benadryl (diphenhydramine) because my allergies are acting up and I'm stuffed up, I have a cough, I'm weeding because my asthma as well. Is it o?

Probably not: I presume you are asking whether it is ok to do some weeding when your nose is stuffed up and your asthma is not controlled. In general, the answer would be no since you are likely allergic to weed pollen and molds from the disturbed soil. It is also important for you to call your doctor about your asthma. Benadryl (diphenhydramine) or any other antihistamine has no decongesting action, nasal steroid does. ...Read more
