Hydroxypropyl methylcellulose eye drops
Function and Efficacy
Hydroxypropyl methylcellulose is a partial methyl and partial polyhydroxypropyl ether of cellulose. It can be dissolved in cold water to form a solution with a certain viscosity. Its properties are close to the viscoelastic substances (mainly mucin) in tears. Therefore, it can be used as artificial tears. Its mechanism of action is: it attaches to the surface of the eyeball through the adsorption of the polymer, simulating the effect of conjunctival mucin, thereby improving the state of reduced eye mucin and increasing the retention time of the eyeball under the state of reduced tears. This adsorption effect is independent of the viscosity of the solution, thus ensuring that solutions with very low viscosity can also have a very long-lasting wetting effect. In addition, it can also increase the stability of the precorneal tear film by significantly reducing the contact angle of the clean corneal surface and increasing the wetting of the cornea.

Suitable for both adults and children. Take 1-2 drops three times a day or as directed by your doctor.
Adverse Reactions
In very rare cases, it may cause eye discomfort, such as eye pain, blurred vision, persistent redness or irritation of the eyeball. If the above eye symptoms persist for more than 3 days after use, you should stop using the drug and go to the hospital for examination if necessary.
Precautions
It is contraindicated for those who are allergic to hydroxypropyl methylcellulose and other excipients such as benzalkonium chloride.
Special Population Medication
Precautions for children: Compared with people in other age groups, the use of Hydroxypropyl Methylcellulose in children does not cause more adverse reactions. Therefore, children can use this product in the same way as adults.
