Took levaquin (levofloxacin) recently due to allergies to other meds. i heard can cause mental issues. is this while taking it or permanent? should i be worried??

No: The problem is its potentially to weaken your tendons causing tears esp at the heels. A few people with a cardiac abnormality may develop rhythm problem from taking levaquin (levofloxacin). Mental problem is not a common issue at all. Having said that, the majority of people who have taken the quinolone class (levaquin (levofloxacin) (levofloxacin) is one) of abx do not end up with complications but safer option be chosen if available.
