Timolol side effects

timolol side effects

Timolol side effects are the unwanted effects someone may experience after using timolol, a beta-blocker frequently given as an eye drop to lower eye pressure. Many people tolerate the medicine well, but side effects can occur locally in the eye and systemically if some of the drug gets into the bloodstream. Local reactions include stinging, burning, dryness, redness, or temporary blurred vision shortly after application. Systemic effects mirror those of oral beta-blockers and can include a slower heart rate, low blood pressure, fatigue, dizziness, and worsening breathing problems for people with asthma or chronic obstructive pulmonary disease. Timolol can also rarely affect mood, mask signs of low blood sugar in diabetics, or interact with other heart and blood pressure medications. Most serious effects are uncommon, but anyone who develops fainting, severe shortness of breath, chest pain, or sudden wheezing should seek medical help right away. Simple measures like pressing the inner corner of the eye after putting in drops or closing the eyes for a minute can reduce how much drug reaches the bloodstream and lower the risk of systemic problems. Because of these possible effects, doctors review medical history and other medicines before prescribing timolol and recommend regular monitoring of heart and lung health. If side effects are bothersome, there are alternative glaucoma medicines and approaches that a doctor can discuss.
