User Voices

The following are comments from users that experienced side effects while taking Timolol Maleate


I used to take Timolol, then got put on Cosopt which has Timolol in it. I found myself a little short of breath on Timolol. Cosopt tends to sting and irritate my eye more than the other drops.

This seems to be working for me so far. It does sting a little going in, but I have had no side effects. Things look a lot brighter to me now, which is great.

I am forced to use timpotic in the ocudose, since it is more gentler. No preservatives. The side effects are discharge, and itchy dry eyes.

Additional Drug Information

* Warning: The facts and figures contained in these reports are accurate to the best of our capability; however, our metrics are only meant to augment your medical knowledge, and should never be used as the sole basis for selecting a new medication. As with any medical decision, be sure to work with your doctor to ensure the best choices are made for your condition.

* About FAERS: The FDA Adverse Event Reporting System (FAERS) is used by FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. Reporting of adverse events is a voluntary process, and not every report is sent to FDA and entered into FAERS. The FAERS database may contain duplicate reports, the report quality is variable, and many factors may influence reporting (e.g., media attention, length of time a drug is marketed, market share). For these reasons, FAERS case reports cannot be used to calculate incidence or estimates of risk for a particular product or compare risks between products.
