How Long Does It Take For An Allergy Medicine To Work
30-60min: Oral antihistamines take anywhere between 30 to 60 minutes to start working. Steroid nasal sprays may take up to 2 weeks, antihistamine nasal sprays take 20 minutes, and other medications can take longer. If your symptoms are bad, you may not notice a significant effect right away from the medications. ...Read more
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
It depends: You don't tell me what your allergic symptoms are nor what medicine you were prescribed. In principle, antihistamines, oral and topical (nasal and ocular) work within 1-2 hours and 15-45 minutes, respectively. Inhaled and oral corticosteroids (cortisone-like) take at least 6 hours to start working, full effect after a few days. ...Read more
I have terrible allergies and I usually take Alavert but it doesn't seem to be helping me anymore what allergy medicine do you suggest will work?
Nasal?: For nasal symptoms, a nasal steroid will likely work better but may take a few days. ...Read more
Confusing question.: I would guess that you are asking whether it is possible to find an allergy medication that works. If so, the answer is yes. However in order to get a better answer, you will have to be more specific on the type of allergic problem you have and what medications you have tried thus far without having any success. ...Read more
Depends: The most frequently used and most available without a prescription are antihistamines. The new generation ones (zyrtec, claritin, allegra, xyzal, (levocetirizine) clarinex) are safe and effective. The most effective treatments for allergic rhinitis are nasal steroid sprays. The strongest allergy medication would likely be considered oral steroids like prednisone, but the significant side effects limit is use. ...Read more
Many: The most effective allergy treatment for allergic rhinitis is the prescription nasal steroid sprays (qnasl, flonase, nasonex, (mometasone) etc) over the counter antihistamines can be very effective including claritin, zyrtec, and allegra. Some people will respond better to one over the other (for unclear reasons). The best long term therapy for significant environmental allergies is allergy injections. ...Read more
Allergy shots/remove: All allergy medications will help with pet allergy, but not eliminate them. It also depends on what pet. Cat allergen is so potent that no medication is going to be truly effective. With dogs, removal from the bedroom, washing hands before going to bed and having "bedroom only clothes" may help significantly. Long term solution is desensitization (allergy shots) by a board-certified allergist. ...Read more
OTC antihistamines: The best treatment is to be dog free. However, otc antihistamines and prescription nasal sprays can be helpful. ...Read more
The treatment of pet dander allergy includes: 1. Avoidance--keep dog out of bedroom and preferably out of house; wash dog at least weekly, use hepa air cleaners in house.
2. Medication: daily use of an antihistamine (zyrtec, claritin, allegra, clarinex, xyzal) may decrease some symptoms. Topical nasal steroids are most effective (qnasl, flonase, etc).
3. Allergy injections: best longterm option. ...Read more
I love cats and really want to adopt one but I'm allergic. Is there a good allergy medicine I can take so I can get one?
Allergy shots: Allergy medications will not take you a long way if you want to live with a cat. I suggest you see an allergist, get tested then get allergy shots for cats before you get one. ...Read more
No: Not if you are taking allergy medicine for canesten oral ingredients, nor take it if you are taking astemezole, or have terfenadine laying around since it has been off market for couple of years now (also known as seldane). ...Read more
No: Similar ingredients. Take one or the other. ...Read more
No but why: Rather than commit to taking medications regularly, see an allergist to identify why you need to take medications long term. Avoidance measures can be useful if the trigger is known. Nasal steroid sprays are more effective than antihistamines and allergy injections can control symptoms long term even after the injections are discontinued and allow less medication use. ...Read more
Generally not: Many people take allergy mede for yrs and yrs. It only treats te symptoms and does nothing to address underlying causes of allergies. Nutrition is important. Supporting immune system is important. Allergy shots or sublingual drop therapy would be a better long term solution. ...Read more
Maybe: I agree with dr. Juster; use caution when mixing narcotics with allergy meds. But, you need to know that hydrocodone is a natural stimulant leading to mast cells releasing histamine and causing itch. Not a true allergy, rather a side effect from the drug. Anti-itch medications can help but they can also worsen drowsiness. Maybe switching to something else would be best. ...Read more
Without food: Fexofenadine (allegra) comes in 2 doses for adults, 60 mg. And 180 mg. The 60 mg dose is taken twice a day, every 12 hr. The 180 mg dose is taken once a day, usually in the morning and it is more effective than 60 mg, 2x/day. Fexofenadine should always be taken 1 hr. Before food because food, especially fatty food, interferes with fexofenadine absorption. ...Read more
