Can loratadine be used for a food allergy in place of benadryl (diphenhydramine)?

Is it safe to take Benadryl (diphenhydramine) after 3 glasses of wine if I feel I may have been exposed to a food allergy of mine?

Is it safe to take Benadryl (diphenhydramine) after 3 glasses of wine if I feel I may have been exposed to a food allergy of mine?

NO: Benadryl (diphenhydramine) makes you groggy like a glass of wine. 3 glasses of wine makes most of the people very groggy. I don't know about you (depend of body mass and tolerance). Having an allergic reaction should be addressed as well especially after that drinking. If the allergic reaction is not severe you consider drinking as much water. If the reaction is severe you need to see a doctor. ...Read more

What type of benadryll and how much benadryll should I give my 17 month old baby? She is also 18 lbs. She has a minor food allergy..

What type of benadryll and how much benadryll should I give my 17 month old baby? She is also 18 lbs. She has a minor food allergy..

Maybe none...: Benadryl only relieves symptoms, it is not needed just because there is an allergy. It helps if the symptoms are hives or runny nose, but likely won't help if the symptoms are diarrhea, vomiting, eczema, or asthma. The best treatment is to avoid what she is allergic to.
If she does need benadryl, make sure it has no other ingredients, only diphenhydramine, and the dose is about 1/2 tsp. ...Read more

Severe hives all over & congestion 2 hrs after eating ham, no prev allergy, no fevr benadryl (diphenhydramine) but Sx returned, ER gave corticosteriod...food or viral?

Could be either: Severe hives and congestion after eating ham...could be due to food, but you describe it occurring 2 hours after eating, which is a bit late for a food related allergic reaction.
