Do antihistamines like Benadryl (diphenhydramine) help prevent oral allergy syndrome?

Probably not. Oral allergy syndrome is usually caused by pollens and sometimes nuts. Claritin, zyrtec and Allegra (fexofenadine) can help with pollen allergies. But like any other allergy, it is best to stay away from the problem. Have an allergist test you and see what treatment would be best.

Does pollen season make oral allergy syndrome worse despite taking antihistamines?

Yes it can. That's why you need to know the triggers well, try to avoid them as much as you can, ask your doctor about keeping an Epipen (epinephrine) handy, just in case a severe reaction develops, see an allergist if you can for complete assessment. Check aaaai.org or acaai.org for an allergist in your area, good luck. Read more...

How often can I give Benadryl (diphenhydramine) to a 7 MS old baby to prevent allergies/dry runny nose? And dosage? It's it ok to apply earache drops?

Every 4 hrs. Up to every 4 hrs if needed. At age 7, the baby can likely tolerate 6 mg of benadryl (diphenhydramine). No problem with ear drops. However if this problem goes on for more than 2 wks, you should contact your pediatrician. Read more...

Have you ever heard of anyone w/true allergy to benadryl (diphenhydramine)? Would this allergy be likely to turn serious? How can someone be allergic to antihistamines?

Yes. Good question. It is very rare but does happen. Sometimes they are not allergic to the Diphenhydramine but the dyes and fillers used to make the medicine. But people have also had reactions to dye free benadryl (diphenhydramine). You can develop an allergy to anything. I have seen people with Benadryl (diphenhydramine) allergy who could take other antihistamines such as hydroxyzine. Read more...

I seem to have developed an allergy to our new dogs. Tried several antihistamines but Benadryl (diphenhydramine) works best. Can I take on a regular basis?

Allergy. Remember the best treatment is avoidance and we have the same problem. I'd sacrifice to be with my dogs too, hehehe. If you can tolerate Benadryl (diphenhydramine) and it's the only thing that works, you can take it regularly, but remember, it can make you sleepy. Have fun with the dogs, i hope you will develop tolerance. Read more...
Here are some... Congratulate for finding Benadryl (diphenhydramine) to relieve the symptoms dog-related allergy. Following Dr. Delrosario's view-avoidance is really decent, though maybe politically incorrect for those who obsess with something like dog as pet. Oftentimes what you need is not what you like. Beware: Life is a constantly changing & adjusting dynamic process of struggle to cope with reality, certainty, & uncertainty.. Read more...

Allergic run. Maybe the antihistimines are not strong enough for the allergic reaction you are suffering from. Maybe you are not taking them in the proper dosage. Check with either your primary doctor or an allergist. They will sort this out for you. Good luck. Feel better. Read more...
