My husband was prescribed the medication "Nitrofur-Macr 100mg" (twice a day) for a bladder infection. It was for 10 days. He has taken 8 days-worth, but now is sick with body aches (possible cold, maybe fever). He is wondering if he can stop the meds now altogether, or if he can stop for a day or so THEN take the rest, or if he should force them now - even though he knows it is going to make him feel even sicker?
