Will the drug help with swollen legs?

You did not write what exactly the drug is about. Cipronex is tagged with the question. If you wanted to ask about this medicine, please read on. Otherwise, please provide the trade name of the preparation you are interested in. Cipronex contains the antibiotic ciprofloxacin - a compound that destroys certain specific bacteria that cause infections. Ciprofloxacin does not have a direct anti-edematous effect. Edema can have very different causes - among them cardiac, on the part of venous and lymphatic vessels, post-traumatic. It is not clear from your entry what causes your legs to be swollen. An antibiotic can only help if the swelling is the result of infection by bacteria sensitive to the antimicrobial drug in question.
