Allegra Overview

Fexofenadine (trade names Allegra, Fexidine, Telfast, Fastofen, Tilfur, Vifas, Telfexo, Allerfexo) is an antihistamine pharmaceutical drug used in the treatment of allergy symptoms, such as hay fever, nasal congestion, and urticaria.[3] Fexofenadine is sometimes called a third-generation antihistamine because it is less able to pass the blood-brain barrier and cause sedation, compared to first-generation antihistamines.[4] Contents 1 Medical uses 1.1 Dosage 2 Side effects 3 Overdose...

redotex and meds
2 Replies RSS
I have chronic hives and take tachrilomus. Would it be safe to take redotex every other day in half a dose? ## Hello, Annie! How are you? No, I can't tell anyone that it is safe to take Redotex in any amount. The FDA has found serious reasons to question its safety. If you need to lose weight, it would be best and safest to talk to your doctor about what might work for you. Is there anything else I can help with? ## I have chronic hives as well (dermatographism) I take 2 Allegra a day and redotex, no side effects. I lose weight and hives under control

can i eat antacid along with allegra 120
2 Replies RSS
I have been eating allegra 120 since last 1 month. my question is can i eat Tritrab-DSR (rabprazole) antacid. ## Hi Rucha, According to, there are no drug interactions listed between Allegra and Rabeprazole. Based off this information alone, I don't see any reason why you wouldn't be able take these two meds together. The only thing I'm weary of when it comes to using more than 1 medication at a time is that in the event of any side effects (god forbid), it may be difficult to determine which medication is the underlying cause. At any rate, please post back if there's anything else I can help with! ## Hi. When you take any medication too close in proximity, time-wise, to an antacid or a laxative, less of whatever you are taking, gets in your system. You need to s...

Does anyone have experience taking more than 180 mg. Allegra daily?
5 Replies RSS
I am wondering if anyone has taken more than 180 mg. of Allegra daily and lived to tell about it! Just kidding about that last part. I have a particularly bad case of post nasal drip and I DO get some relief from the 180. However, I am considering trying half a tab (90 mg.) at night to get more relief. I KNOW what the recommendation is...I am just wondering. Has anyone tried it? ## Actually, if you're currently taking that much and still have post-nasal drip, then it's most likely time to try something else, rather than more of the Allegra. What other allergy medications have you tried? There are others on the market, some are available over the counter and some by prescription. Have you talked to your doctor about it? What are you allergic to? ## When it comes to prescription m...

Allegra D 12 hour extended release
1 Reply RSS
Hi, I have been taking the Allegra D 12 for a few weeks now & it really works excellently for me! I know this sounds gross but my doctor has me check my stool because of a prior but cured events! Lol... So...I'm curious as to why my body does not digest the brown portion of the pill!? Any ideas anyone? ## Hello, Ryan! How are you? Because that's the time released portion. The outer shell is part of what helps it to release slowly, over time, as it absorbs fluid in your stomach. Then, the empty shell is expelled as waste. The FDA lists the typical side effects of this medication as possibly including nausea, dizziness, dry mouth and insomnia. Is there anything else I can help with?

I was taking Losar H due to high bp (190/82). I started getting angiodema since it is an ACE inhibitor. Now I am taking Losar 50 twice daily for last 10 days. But still I am getting affected by Angiodema with reduced intensity almost every two days. I have come to USA (MA) on tour from India for 4 months and will stay here till July. The occurance of Angiodema is more frequent here in USA. Suggest some remidies pl. Can I take Allegra 180 regularly? Angiodema is significantly less if I take Allegra 180. ## Hello, Tapan! How are you doing? I'm not a doctor, so I can't say what medication is or isn't safe for you to take. It might be a better idea for you to switch off the Losartan and start taking something else. There are other options available that may not cause the same is...

started taking allegra after four days wake up at night hard to breath its like a weight on my chest and I panic feels like I may die goes away in 10-15 minutes happened twice I stopped taking the allegra and these symtoms are gone. Any one out there have these symstoms while taking allegra. Thanks ## @John, Sorry to hear about your experience with Allegra. According to, "chest tightness" and "trouble breathing" are both listed as an allergic reaction to Allegra (fexofenadine). They go on to note that you should contact your doctor right away if any of these symptoms manifest. Having said that, it sounds like adhering to these precautions would probably be a wise decision. Perhaps your doctor can suggest another alternative if anything, just to play it safe. Hope...
