Should a child who reacted to blueberry with full-body hives and swollen lips carry an EpiPen (epinephrine)? Blueberries seem easy enough to avoid.

Should a child who reacted to blueberry with full-body hives and swollen lips carry an EpiPen (epinephrine)? Blueberries seem easy enough to avoid.

Don't assume: Not the blueberries; willing to bet. 25 yrs an allergist, true cases are exceedingly rare. May not be even food. May not even be anaphylaxis; just idiopathic urticaria with angioedema. See an allergist. Why label and carry epi unneccessarily? Sounds like you have enough on your hands. Just saying. Get allergy consult and accurate testing. ...Read more

I think have the hives because I have random red spots and swollen lips. Is Claritin good or Benadryl (diphenhydramine) better?

I think have the hives because I have random red spots and swollen lips. Is Claritin good or Benadryl (diphenhydramine) better?

Zyrtec (cetirizine) (Cetitizine): If these are recurrent, see an allergiist for the propper diagnosis and treatment. For otc (over the counter) medication, most allergists prefer zyrtec (cetirizine) because it has more anti-inflamatory properties and lasts 24 hours. Benadryl (diphenhydramine) generally lasts 4 to 6 hours and causes more drowsiness, if the patient gets drowsy on zyrtec they might try Allegra (fexofenadine). ...Read more

Slighty swollen lip, and no known allergies. Plus I didn't have any food or drink I don't usually have. What could be the cause? Should I worry?

Depends: If you have no problem breathing (throat swelling), you may try antihistamine up to 4 times daily to see if this helps. If the problem keeps on coming back, consider consulting an allergist. There are many potential causes and a drug reaction (especially NSAIDs) is one to be considered. If you have any problem breathing or swallowing, rush to the ER. ...Read more

Husband has Poison Ivy 9/5. Got Predisone. Allergic Reaction. Just on Benadryl (diphenhydramine) now. Still swollen and red and more hives are appearing?

Prednisone allergy?: I am uncertain he had a prednisone allergy. You need to discuss the reaction with your physician. This may have been related tot eh dose of the prednisone and was a side effect of the level of the dosage. Prednisone is a corticosteroid and these are the mainstay of acute therapy for poison ivy. You can discuss this your physician and see a dermatologist. You may need a different preparation ...Read more

I had an allergic reaction to bactrim (sulfamethoxazole and trimethoprim) on 1/11/14 (swollen lips and rashes on abdomen & back arm). I was given doxycycline hyclate. Rash became bumps?

Bactrim (sulfamethoxazole and trimethoprim): If you meant that the rash was progressing without interruption despite switching to doxycycline, I would venture that the rash is just from the progression of the sulfa rash since the process will likely last for a week or two. Beware of sunlight exposure from doxycyline which may give a nasty sunburn for some people. ...Read more

I have developed a very swollen bottom lip. Not sure if allergic reaction or bite. I have taken Tellerge 180 mg over an hour ago? No change. Can I take Celestamine as well? What else can I do to reduce swelling. It is quite painful.

I have developed a very swollen bottom lip. Not sure if allergic reaction or bite. I have taken Tellerge 180 mg over an hour ago? No change. Can I take Celestamine as well? What else can I do to reduce swelling. It is quite painful.

Angioedema: The commonest cause of swelling of the lip in the absence of trauma or infection is an allergic reaction. You have already taken an antihistamine. Celestamine contains antihistamine but also has a cortisone like substance which may be helpful. Applying a cold compress may also help. Angioedema usually subsides within 24 hours. If you have associated throat or breathing problems go to emergency roo ...Read more
