<s>[INST] hi I had 9 teeth removed last Wednesday. I was put on amoxicillin .500 mg. times a day. now I have a rash. the dentist told me to stop taking the medication, but now I have a rash like hives. I need something to relieve the itch and how long will the itch last. thank you [/INST] Hello and welcome to HCM.forum,I would like you to know that if the rashes developed after taking amoxicillin then you should stop taking it and visit your doctor soon.For now i will advise you to take an anti allergic which will provide you temporary relief.Also you can apply cold compresses to relieve itching and redness.Kindly see you doctor soon.I hope i answered your query.I wish you good health.Take care. </s>
