Hypromellose

What it is used for

• Keratoconjunctivitis sicca (dry eye) / Ocular lubrication
• Ocular lubrication (e.g., during anesthesia or for exophthalmos)
• Ocular lubrication

How it is given

Possible side effects

• Transient blurred vision immediately after application
• Mild ocular irritation or stinging (rare)
• Crusting on the eyelids from dried polymer

Cautions & contraindications

• Hypersensitivity to hypromellose or any component of the formulation (such as preservatives like benzalkonium chloride in multi-dose bottles)
• > **Contamination Risk:** Do not touch the dropper tip to any surface, including the eye or eyelid, to avoid bacterial contamination of the bottle. > **Timing:** If using multiple topical ophthalmic medications, administer hypromellose last, or wait at least 5-10 minutes between applications to prevent washout of the preceding drug. > **Preservatives:** Multi-dose bottles often contain preservatives (e.g., benzalkonium chloride) which can be epitheliotoxic with very frequent use (e.g., >4-6 times daily). Consider preservative-free single-use vials for severe dry eye requiring highly frequent application.

Drug interactions

• Other topical ophthalmic medications: May wash out other eye drops if administered simultaneously. Hypromellose can also act as a barrier if applied before other drugs.
