Eyes Home > Timolol Side Effects
Nausea, dizziness, and a slow heart rate are among the most common side effects of timolol tablets. For the eyedrops, negative reactions may include blurred vision and eye burning or stinging. In most cases, side effects are mild and easily treated. However, notify your healthcare provider if you develop problems such as difficulty breathing, hallucinations, or rapid weight gain.
An Introduction to Side Effects of TimololJust like any medicine, timolol (Betimol®, Blocadren®, Istalol®, Timoptic®) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
Common Timolol Side EffectsTimolol has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and compared to those that occurred in another group of people taking either a similar medication or, in some cases, a placebo (a "sugar pill" that does not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group not taking the medicine.
