Levofloxacin capsules usually refer to levofloxacin lactate capsules. This medication generally does not cause heart disease. Levofloxacin lactate capsules belong to the macrolide class of antibiotics and can treat urinary tract infections, skin infections, and other conditions caused by susceptible bacteria. Improper use of this drug may lead to adverse reactions such as dizziness and palpitations, but it usually does not affect cardiac function or cause heart disease. Symptoms typically gradually subside after discontinuation of the medication.
