For how long does the amoxicillin rash last and what can I do to get rid of it?

Amoxicillin rash: Amoxicillin is a penicillin type medication, so unfortunately, this means you are allergic. Usually these rashes are quite mild. Once you stop the drug, it will get out of your system within a day, and the rash should start to settle down. This can take anywhere from 1 to 6 days depending on how bad it was to begin with. The average is 3 days. There's nothing you can do to make it go faster. Sorry ...Read more

Son had allergic reaction to amoxicillin, full body rash, stopped meds, rash cleared up 6days ago, but now it looks like its coming back what, to do?

Seek wisdom: Rashes are a large part of pediatric care. Common dilemma is that viruses often cause harmless rashes (exanthums), but drugs used to treat secondary ear infections, sinusitis, etc. Can be serious. Appearance, timing of rash is important. Recognition by a seasoned provider can be enormously reassuring. Allergists are called upon for diffucult rashes and can test for certain drug allergies. ...Read more

17 yr old daughter has mono and morbilliform rash. Amoxicillin ceased Wed. Prednisone and Benadbut spreading body rash & severe itch. No fever. Help?

17 yr old daughter has mono and morbilliform rash. Amoxicillin ceased Wed. Prednisone and Benadbut spreading body rash & severe itch. No fever. Help?

Rash: Using amoxicillin with mono frequently causes an itchy uncomfortable rash. It lasts a while. The prednisone may not be the answer. I would use Zyrtec (cetirizine) and add Benedryl both if needed. Drink lots of fluids and rest. Bathe too. Mono can last 2-3, weeks and it is miserable. It is a lesson learned about over using antibiotics. Sorry you were the one to experience this. It will get better. ...Read more

Does getting a rash from amoxicillin necessarily suggest mono?

Does getting a rash from amoxicillin necessarily suggest mono?

It's a decent bet...: Amoxicillin is notorious for causing rashes in patients with mono--it typically looks like a dense, deep red, symmetric rash esp on the chest, back, and abdomen, but elsewhere also. It is different than hives, which are scattered, irregular raised "welts" that itch badly. You're perfectly correct that the rash merely suggests mono, but doesn't prove it. You'll want to confirm it with lab tests. ...Read more
