It’s important to know if you have an allergy to this antibiotic. For those that do, you may have Type E immunoglobulin antibodies that are produced which cause problems. In this case your body is reacting to the penicillin as though it’s the enemy. Be aware that you need to amoxicillin will not be tolerated by your system as well.
An allergic reaction to penicillin may not appear immediately but may take a few to several days to be exhibited. It can show up as an itchy rash. If you notice any swelling of the face, throat or breathing issues you should seek medical attention immediately. Anaphylactic shock is serious and having one’s airway obstructed can be an emergency situation. This usually occurs shortly after taking the medication whereas the antibiotic rash may not manifest itself for several days.
For a penicllin rash without any swelling complications, taking an antihistamine can relieve the itching.
