Steroid nasal sprays: While steroid nasal sprays may have some activity on reducing nasal inflammation as soon as 12 hours after a single dose, they don't achieve their maximum effect for several days. If you are having nasal congestion causing a sinus headache, you may need to take an oral or intranasal decongestant or antihistamine to get more temporary relief while the steroid spray takes effect. ...Read more

How long does it take for eustachion tube dysfunction from allergies to go away with antihistamines and steroid nasal sprays?
Depends: The opening depends on the patency at the nasopharyngeal area. Antihistamines by mouth do not decongest the nasopharyngeal area although nasal steroid if aimed laterally often does. The optimal decongesting effect from nasal steroid is at 5-7 day of daily use. If the problem persists, consult an allergist. ...Read more

Was prescribed an allergy nasal spray to help with buzzing in ears. How long does it usually take for this to work & can I try anything else?
Probably never: For people with plugged ears, allergy nasal spray may help and the optimal effect is reached between 5-7 days. However most buzzing or tinnitus in the absence of other inner ear involvement, would not be helped by the spray. Often the cause is unknown. Suggest you consult an ENT doctor . ...Read more

I have been taking Benadryl (diphenhydramine) for allergies. It makes me tired. Will this go away with time?
Usually not: The sedating effect of Benadryl (diphenhydramine) may get a little better with time, but will not likely totally go away. There are many non-sedating antihistamines and allergy medications out there, so i suggest talking to your local pharmacist or your primary care doctor about over the counter or prescription alternatives. ...Read more
I have a chronic runny nose during allergy season, but no other allergy symptoms such as itchy eyes or sneezing. Is there an antihistamine that tends to work better for runny nose only? How long should I stay on an antihistamine to tell if it works befo
Allegra & Claritin (loratadine): Allegra (fexofenadine) & Claritin (loratadine) (loratidine) have the advantage of long duration of action (~24 hours) and lack of sedation. Zyrtec (cetirizine) is nearly as good but 1 in 12 users get drowsy on this one. All otc antihistamines treat all symptoms of allergic noses and eyes except for stuffy nose. Buy the generic versions and get the same effect at lower cost. ...Read moreSee 1 more doctor answer
Couple days: You should start to see improvement in 1-2 days and it will gradually build with continued use. By 2 weeks, efficacy should be up to 80% and by 4 weeks, nearly 100%. That's why its so important to use it regularly, because it doesn't work that great if only used intermittently "as needed.". ...Read moreSee 2 more doctor answers

Took 25mg hydroxyzine. Not really working for itchiness. How long should at most to wait too see an effect? Gave me runny nose
Also used for anxiety.
Six hours.: Hydroxyzine is dosed every six hours as needed. So if you see no benefit after six hours, you can take another dose. Realize that it can make you groggy, so don't take it if you have to drive someplace or do something important. ...Read more
Claritin (loratadine) does not take away my terrible hives caused by macrobid, will zyrtec do the job?
I'm experiencing seasonal allergies with congestion and sneezing. Does Claritin (loratadine) take a few days to take effect, or is there something better?
Choices exist : Claritin should work relatively quickly, but some antihistamines work better for some people than others. Zyrtec or Allegra can be tried as over the counter rx. Otherwise, one of the best rx available by prescription(based on several studies) is Dymista nasal spray. It is a nasal steroid and antihistamine combination spray. This should handle your symptoms. ...Read moreSee 1 more doctor answer
Is zyrtec or allegra (fexofenadine) better for chronic hives of unknown cause? Can i take either one daily & will it help hives go away?
Probably but: Yes, it usually helps and you may take even up to 4 x daily (or 4x the average dose) if necessary. Zyrtec works a little faster and may be more potent than Allegra (fexofenadine) but there is a small chance of getting drowsy. At times hives can be so severe that no antihistamine would control them. If this has been present for >8 wks, consider seeing an allergist. ...Read more
I get headaches from allergies. Can i take Claritin (loratadine) and zyrtec at the same time? Claritin (loratadine) didn't work alone when i traveled away from home.
Yes, but: Both Claritin (loratadine) and zyrtec (cetirizine) are new generation antihistamines. While there is no harm to using them together, there is likely no added benefit either. The most effective treatment for nasal allergies is the topical nasal steroid sprays such as qnasl, flonase, veramyst, nasonex, (mometasone) etc if a person doesn't have relief with an antihistamine alone. ...Read more
I have seasonal allergies and they tend to get real bad and over the counter doesnt work only prescription why is that ? Why does counter doesnt work
Many: Whether your allergies can be controlled by any drug or drugs depends on (a)How intense the allergen exposure (b) the primary mediators causing the inflammation (c) the potency of the medication (d) the technique in delivering the medication especially related to nasal sprays. I think you should consult an allergist about your problem. If medications works for all, there's no need for allergist. ...Read more
