What Is Zantac Allergy
Not exactly: Zantac (ranitidine) is an h2 (histamine) blocker that is typically used for ge (acid) reflux. However, it is commonly used to treat chronic hives in combination with traditional antihistamines. It is also used for additional treatment of severe (anaphylaxis) allergic reactions although first line treatment is Epinephrine and h1 antihistamine. It will not help allergic rhinitis. ...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
Uncommon: Zantac (ranitidine) is an h2 receptor blocker (a different histamine receptor). A very common side effect of Zantac (ranitidine) is nausea, GI upset and diarrhea. If you are experiencing these, then it is not an allergy but rather a side effect of the medication. Although an allergy is very unusual for this medication, it is still a possibility. See an allergist. ...Read more
Add-on for hives: Ranitidine (zantac), although it's a different kind of histamine blocker (h2 for acid vs h1 for allergies), has been shown to have some anti-allergy properties, especially when used with an h1 blocker like Benadryl (diphenhydramine) for hives. There was actually one study that showed benefit in nasal allergies, but i don't know anyone that prescribes it for that purpose. ...Read moreSee 1 more doctor answer
Is it possible that Zantac, being a histamine blocker, could cause higher histamine production when coming off of it, resulting in development of allergies? For example consuming diet soda can result in insulin spikes in some cases, possibly leading to di
No: Zantac (ranitidine) is a histamine 2 receptor reverse agonist and would not significantly affect histamine production.when withdrawn. There is a theoretical possibility that Zantac (ranitidine) itself may lead to more histamine release by blocking the histamine 2 receptor(which acts as a feedback switch) but this has not been clinically a significant issue. ...Read more
2 week old baby vomitted last night, doc today says its reflux. Gave her zantac, (ranitidine) vomitted again after next feeding. Could this be an allergy?
Can i give my 15 month old peptobismol? She keeps throwing up with no signs of fever or illness. We have checked food allergies, ans GERD (taking zantac (ranitidine) 2x daily). I cannot figure out what's wrong :-(
I wouldn't: Pepto has salycilates which we don't give tom kids under 16 because of an association with liver failure/death (Reye syndrome).Wet burps that do not result in problems with hydration often decrease with age as the reflux improves.If the kid is growing well. I would leave it alone. ...Read more

Any cow milk product: Cow's milk is present in most cheeses, yoghurt, cream, butter and hence virtually all dairy. You must read the labels to know for sure. Soy based formulas are the most common alternatives. Your pediatrician should help you select a formula that is milk-free.

My 13 week old is on 0.6mls ranitidine for reflux now my doctor think he has a cows milk allergy. He is fussy, wont nap and doesn't sleep through night?
Other suggestions: I agree that your son may have a cows milk allergy or lack of tolerance to milk. If there is a history of allergic disease in the family, a rash called eczema then it is more likely to be an allergic reaction. If he continues to spit up while on the medication, a dose adjustment for his weight may be needed. I would also suggest that he feed at around a 40 degree angle. ...Read moreSee 1 more doctor answer
I had an allergy to doxycycline 4 weeks ago i can't take benedryl and I took prednisone for 12 days and I still itch, I have been taking ranitidine?
Cause?: I doubt that the allergy to doxycycline can linger on this long and thus your itching must be from something else. In the absence of skin rash, dry skin is the most common cause for itching. Have you tried applying a moisturizer on your body 2x daily with one <3 mins after bathing? ...Read more
I'm 21 year old male and been having this feeling of something stuck in my throat I have been taken 150m of zantec my doc gave me for GERD but the feeling still is there what can this be the acid allergies or just anxiety?
Yes : There are now 4 types of histamine receptors. Zantac (ranitidine) acts on the h2 receptor resulting in blocking stomach acid thereby treating heartburn. Allergies are treated with h1 blocking type medications including claritin, (loratadine) zyrtec and allegra. Some medications have both actions to block both h1 and h2 receptor. For anaphylaxis, zantac can be added for it's effect on blood vessels. ...Read more

Yes: Zantac is an H2-blocker that reduces stomach acid and has a medium anticholinergic side effect. Zoloft is an SSRI for anxiety/depression and has low anticholinergic activity. Combinations of medications with anticholinergic properties may cumulatively increase the risk for adverse peripheral anticholinergic effects such as constipation, urinary retention, dry mouth and dry eyes. ...Read more
