Claritin And Allegra
Fexofenadine is an antihistamine which is used to treat allergies such as hayfever, and hives. It can be taken once or twice a day. It is a second generation antihistamine and does not cause as much drowsiness as other antihistamines such as Diphenhydramine (benaryl) or chlorpheniramine. Always be careful about drowsiness with any antihistamine especially if driving ...Read more
You shouldn't: All of those medications are in the same class called non-sedating antihistamines. They should not be taken at the same time. ...Read more
I take OTC allergy meds everyday. I heard it can be helpful to switch OTC allergy meds every 3-4 months. Is this true? Zyrtec, Claritin, (loratadine) Allegra?
Similar medications: The medications you mentioned have the same mechanism of action. Everyone's body may have a different response to medications. Some studies have indicated that tolerance to antihistamines does not occur however switching to find which works best for you is reasonable. The best medication = the one with lowest side effects and works! Consider saline and nasal steroid spray or allergy testing. ...Read moreSee 1 more doctor answer
Similar medicines: All of these medicines are antihistamines. Taking combinations of antihistamines increases the possibility of side effects. If antihistamines are not working at recommended doses see a doctor. You may need a different type of treatment for your problem. ...Read more
None of these: These medications are antihistamines which counter the affects of allergies. They are not antibiotics which are typically prescribed for sinus infections. Decongestants and sinus rinses may help with the symptoms associated with the sinus infection, but these antihistamine medications, in my experience, do little for this condition. ...Read more
Zyrtec, claritin, (loratadine) allegra, clarinex. Other allergy pill options? Year-round, persistant allergies. Wet in ears, post-nasal drip (sore throat).
Before you go : Looking for another allergy medication, i would keep the one that works best for you and take it diligently everyday with a steroid nasal spray twice daily for a month to see a big difference with just burst of meds here and there and only when you feel like it. If you have already done this, then it is time to see your doctor, possibly referral to allergist or ENT depends on what the problem is. ...Read moreSee 1 more doctor answer

You could benefit from allergy testing and a detailed nasal and sinus exam. ...Read more
Yes, but use caution: What are you taking them for is most important. Oral antihistamines can cause drowsiness although Allegra (fexofenadine) does not cross the blood brain barrier. The best treatment is to see an allergist for specific treatment. Also, choose whichever antihistamine works best and you can use this twice daily instead of one of each. ...Read more
Yes, but why: Zyrtec, Claritin (loratadine) and Allegra are all new generation antihistamines. While there is no contraindication to taking them on the same day, usually it is not necessary. If symptoms are not controlled, consider seeing an allergist to identify the trigger---with allergen avoidance, comes less symptoms and less medication! ...Read more
They are safe meds: Claritin/allegra, available otc as generic loratadine/fexofenadine, are nonsedating antihistamines, often used for seasonal allergic rhinitis.

What is the difference, if any, between zyrtec, claritin, (loratadine) or allegra in their effectiveness for springtime allergies?
I have very bad seasonal allergies. I have tried everything, Zyrtec, Claritin (loratadine) and Allegra. Nothing works, what can I take?
See an allergist: If none of these OTC meds worked, unlikely that anything else will, you need to be evaluated, good history and physical examination. See your doctor first for initial evaluation, who would refer you or check aaaai.org or acaai.org for an allergist in your area, best wishes ...Read more
Is there anything inexpebsive that can be done for year round nasal allergies besides generic claritin, zyrtec, or allegra?
May be: Any antihistamine will help with the itching and runny nose, but may not help with stuffiness. Older antihistamines are sedating and best taken at night. You should rinse your nose with a saline spray (ocean spray, neilmed). If ineffective, you need a prescription nasal spray from a physician. You can order cheap generic medications from nevada board of pharma -approved canadian pharmacies. ...Read moreSee 2 more doctor answers
Can antihistamines make my hypoglycemia worse? Seems like i'm having more low blood sugar occurrences while on Claritin (loratadine) or allegra.
Probably not: There is no theoretical reason why antihistamines should lower blood sugar. It may be related to the reason you are on the antihistamines or some other medicine that you are taking or the fact that your dietary intake may be different at those times. Try to discuss this in detail with your doctor. ...Read more
