my reaction to 4 500 mg of Amoxicillian was onset difficulty in breathing
no rash in fact I had the weeks prior taken several Amoxicillian for tooth infection.
It was the 4 tablets pre med for plastic heart valve that almost killed me.
Dr said I am not alergic. However I will never us that again Clindamycin works better.
The anaphylaxis was due to the value reaction to 4 pills at once.
