Can my wife take 1 year old antibiotics ciprofloxacin ? she needs it maybe to treat an infection? help please.

No: When a doctor prescribes antibiotics, the entire amount is to be consumed as directed. Left over antibiotic that you have may not be correct for her infection and you would not have the correct amount for her to take. When patients stop their antibiotics prior to finishing them, they run the risk of bacteria resistance and more difficult to fight re-infection. See your doctor.

Antibiotics: Antibiotics are prescribed and should not be self administered, she needs to consult with a physician to see if antibiotics are needed to treat what she had, she should not self medicate.
