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

No much OTC meds: If you have real food allergy and you break out in hives when you eat that particular food, beside benadryl, (diphenhydramine) there are not much otc meds you can take.

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

Swollen lips & blisters since 5:45am, saw hospital was given antihistamines and steroids, told POSSIBLE FOOD ALLERGY. swelling returned it now 10:32pm?

Airway?: Keep in mind the half life of your antihistamine. It is probably wearing off and needs to be redosed. If not improving within an hour of redosing you need to go back to the ER. Cetirizine 10mg will last 24 hours. ...Read more
