Systemic diseases and medications known to cause or worsen dry eye. These don’t replace your dry eye diagnosis — they explain it.

Your dry eye diagnosis describes what is wrong on the ocular surface — the subtype, the tear film deficiency, the eyelid or surface findings. Your associated conditions describe why. A patient with severe MGD and a patient with severe Sjögren’s may both have aqueous-deficient dry eye, but the treatment, monitoring, and prognosis differ. Keeping the two records separate lets your clinician see both at a glance.
Four groups of conditions that frequently drive dry eye disease.
The immune system attacks healthy tissue, including tear- and saliva-producing glands.
Hormonal and metabolic shifts that disrupt tear film composition.
Skin inflammation around the face that spreads to the eyelid margins.
Nerve and central-nervous-system contributions to dry eye and to symptom perception.
Common drug classes known to reduce tear production or destabilize the tear film. If you’re on any of these, your clinician will want to know.
Designed to dry up secretions: antihistamines (Benadryl, Zyrtec, Claritin), oral decongestants (Sudafed).
Anticholinergic effects block tear secretion: antidepressants (TCAs, SSRIs), anxiolytics, antipsychotics, Parkinson’s meds.
Reduce systemic fluid: diuretics (hydrochlorothiazide, furosemide), beta-blockers (metoprolol, atenolol, propranolol).
Isotretinoin (Accutane) — the highest drug-related risk for dry eye. Causes meibomian gland atrophy.
HRT (estrogen-only) and oral contraceptives alter lacrimal and meibomian cellular balance.
High-dose NSAIDs (ibuprofen, naproxen), hydroxychloroquine (lupus, RA).
Never stop a prescribed medication on your own. Your clinician will weigh the benefit against the dry eye risk and may switch to an alternative if needed.
