Antibiotics Home > Ciprofloxacin Side Effects
Although most people tolerate ciprofloxacin well, side effects can occur, and will vary, based on the various forms of this medication. For example, some of the most common reactions with oral or injectable ciprofloxacin products include nausea, headaches, and dizziness, while the ear drops may cause problems such as ear pain or itching in the ear.
An Introduction to Ciprofloxacin Side EffectsJust like any medicine, ciprofloxacin can cause side effects. However, not everyone who takes the medication will have problems. In fact, some people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
Possible Side Effects of CiprofloxacinCiprofloxacin has been studied extensively in clinical trials. In these studies, the side effects that occurred in a group of people taking ciprofloxacin were documented and then compared to those that occurred in a similar group of people taking either a placebo (a "sugar pill" that does not contain any active ingredients) or another antibiotic.
