- blurred vision,
- double vision,
- drooping eyelid,
- burning or stinging in your eye,
- eye itching or redness,
- watery eyes,
- feeling as if something is in the eye,
- cold feeling in your hands or feet,
- ringing in your ears,
- dry mouth,
- loss of appetite,
- upset stomach,
- skin rash or worsening psoriasis,
- sleep problems (insomnia),
- cough, or

Tell your doctor if you have unlikely but serious side effects of Timoptic including:
- eye pain/swelling/discharge,
- slow or irregular heartbeat,
- muscle weakness,
- mental/mood changes, or
- coldness/numbness/pain in the hands or feet.
The usual starting dose of Timoptic is one drop of 0.25 percent in the affected eye(s) twice a day. Timoptic may interact with oral beta-blockers, calcium antagonists, catecholamine-depleting drugs, digitalis, quinidine, SSRI antidepressants, clonidine, and injectable epinephrine. Tell your doctor all medications and supplements you use. It is not known whether timolol ophthalmic is harmful to an unborn baby, so Timoptic should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Timolol ophthalmic is excreted into human breast milk. Because of the potential for serious adverse reactions from TIMOPTIC in nursing infants, a decision should be made whether to discontinue breastfeeding or to discontinue the drug.
