Medications and eye health
Clinically reviewed · Last reviewed 2026-06-13
Why your drug list matters
Eye specialists choose drops, surgery timing and screening schedules based on your whole health picture. Blood thinners affect surgery planning. Steroids raise glaucoma and cataract risk. Some drugs interact with pupil-dilating drops used at eye tests.
Medicines often linked to eye effects
Examples your clinician may ask about include:
- Hydroxychloroquine (Plaquenil) — retinal screening needed long term
- Steroid tablets, inhalers or drops — glaucoma and cataract risk
- Amiodarone — corneal deposits and optic nerve issues
- Ethambutol — optic nerve toxicity
- Anticholinergics and some antidepressants — dry eye or blurred vision
- Tamsulosin and similar prostate medicines — floppy iris during cataract surgery
Eye drops are medicines too
Glaucoma drops can affect heart and lungs. Long-term steroid drops raise eye pressure. Share all bottles you use, including any from other doctors or countries.
What to do if you notice changes
Report new blurred vision, colour vision change, halos, dry or painful eyes after starting a medicine. Your prescriber may adjust the dose or offer alternatives. Sudden vision loss always needs emergency care regardless of medicines.
Frequently asked questions
Can I stop a medicine if it affects my eyes?
Do not stop prescription medicines without medical advice. Contact the prescriber promptly to discuss risks and alternatives.
Do vitamins harm the eyes?
Standard doses of AREDS-style supplements for macular degeneration are usually safe as advised. High-dose nicotinic acid can affect lids and eyes — mention all supplements at eye visits.
Should I bring my medicines to eye appointments?
Yes, or bring a current list with doses. It is one of the most useful things you can do for safe eye care.
