I am very nauseated after just taking the first dose Of this prescribed Medication. It is for a sinus infection I was on Pennicillin for 10 days to get rid of strep throat.. I finished that on dec.25. I was well and then it seems i started with cough head ache , and runny nose, and went back to the walk in clinic. The doctor said it appears it is a sinus infection. He gave me Cefuroxime Axetel 500 mg. I took it with Yogurt and I am so nauseated. Help!!!
