How Medications and Systemic Illnesses Affect Dry Eye: A Guide for Patients

Medications for allergies, such as diphenhydramine, often reduce your tear production. This leads to dry, itchy, or gritty feeling eyes that may blur your vision, especially if you use these medicines often. Lubricating eye drops can help relieve these symptoms and keep your eyes comfortable.

Beta-blockers and diuretics, medications for high blood pressure, may cause dryness, blurry vision, or sensitivity to light. These side effects are usually mild but regular eye exams are important to detect any changes early.

NSAIDs such as ibuprofen, taken in high doses or over long periods, can sometimes cause corneal swelling or light sensitivity. Rarely, more serious problems like corneal ulcers may develop if symptoms are ignored. Talk to our eye doctors about safer pain relief options as needed.

Certain antibiotics, including ethambutol, can affect the optic nerve over time, causing changes in color vision or side vision. If you use these medications for longer periods, regular eye tests can help spot issues before they become permanent.

Taking oral steroids such as prednisone may raise your eye pressure and increase the risk for glaucoma. Symptoms to watch for include headaches or halos around lights. We can monitor your eye pressure and adjust care to lower risk safely.

Anticoagulants like warfarin may raise the risk of bleeding inside your eye, leading to sudden floaters or dark spots in your vision. Seek help right away for new vision changes.

Birth control pills and other hormone treatments can lower tear production, causing dryness or irritation. These effects typically improve over time, and lubricating drops may ease discomfort in the meantime.

Some chemotherapy and targeted therapies may cause dry eyes, eyelid irritation, or changes in your retina. Using preservative-free artificial tears and scheduling regular eye exams can help you stay comfortable during treatment.

Never stop any medication without talking to your doctor first. Our eye doctors can help you discuss safe options for managing side effects.

For most health conditions, you should have annual or bi-annual eye exams, but people with diabetes require yearly screenings. Our team will recommend the best schedule for you.

Dry eye started soon after beginning a new drug is likely linked to the medication, while dryness from chronic conditions such as Sjogren’s syndrome tends to be more severe and ongoing.

Watch for changes in color vision, side vision, or new blurry spots. If you notice these, let your eye doctor know promptly for further tests.

Many patients can continue wearing contacts by using daily disposable types, special rewetting drops, and reducing wear time. If symptoms continue, your doctor may suggest a temporary break.

Rarely, topiramate may trigger angle-closure glaucoma with sudden red eyes, blurry vision, and headaches. These require immediate attention the same day.

Certain vitamins and nutrients may support eye health and counteract dryness. Always speak with your eye doctor before starting supplements.

• Omega-3 fatty acids can improve tear quality.
• Lutein and zeaxanthin help support your retina.
• Vitamins C and E act as antioxidants for eye health.
