Fainting, breathing difficulty, irregular or slow heartbeat (bradycardia), sudden weight gain, swelling of the legs or feet.

These are the most prominent side effects.

Please read the list of side effects that came with your prescription for more details. Or, you can visit your pharmacist and ask for a detailed list of side effects.

If you experience a serious side effect from Timolol or any other medication you should report it to the FDA (food and drug administration).
