Could The Spreading Hives On Lower Back Due To Being On Penicillin For Abscess In Tooth Or Due To BP Medication?

I recently found out or thought I had found out what was giving me hives on my lower back and then it moves all over but mostly on back and thighs/knees. I had been taking different types of penicillan since March, of and on for a tooth that was absessed. After giving me another perscription, I tried to get caught up with the 4 a day (on the second day) after I took the 4th pill, I was broke out so bad, i thought I would have to go to the hospital. Benedryl does not seem to reach it unless I take two. I stopped taking the meds and alerted everyone I was allergic. I have not taken any since last Saturday Jan 4. How long does it stay in your system? and I was put on blood pressure meds last week. Reason being, I am breaking out again. Looking at information online, could my blood pressure med also be a cause of the hives or allergy? So why the heck does this make you believe it is free when now I have to pay for the answer. What a joke.

Hi, thank you for asking Healthcare Magic.
I have gone through your query and understood your concerns.
Hives are one of the side effects of amoxicillin but could still be a reaction to a wide range of allergies. Amoxicillin does not stay in the body for long. In about 8 hours following ingestion, more than 60% would be eliminated.
If the rash disappeared after stopping amoxicillin, then it could be possible that amoxicilin was the cause.
You may also need to avoid other penicillins because they will behave the same like amoxicillin.

I hope that answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. We will be delighted to answer more questions from you.
I wish you good health
