Nitrofurantoin Anhydrous and lips

I took the pill for 7 days and did not realize or associate the side effects to the drug. Initially I experienc ed extreme tiredness, felt lousy, unmotivated etc..... then by the 7 th day after taking the last pill I woke up itching all
over my entire body. When I woke the next morning I had broken out in hives all over my entire body as the hours progressed I became swollen ( my feet, my ankles, my legs) ,sore (all over) and itchy: basically physically incapacitated. By the next morning although some of the symptons had subsided I awoke looking as if I had been beaten up my lips were extremely swollen and my face bruised and puffy. This is the allergic reaction I experienced unfortunatley not associating it with the drug soon enough to avoid.
