Hydroxypropyl Methylcellulose is the ingredient in contact
solutions and drops that keep dry eyes moist. It prevents damage to
the eye in certain eye diseases.
The ways that it could damage you in any way was if you had an
allergy to Hydroxypropyl Methylcellulose, pregnant/breasfeeding,
and children and elderly adults.
There are no studies done comparing young children and the
elderly's reaction to Hydroxypropyl Methylcellulose. In some cases
the elderly have different side effects/reactions and the data just
isn't there. In children it is expected not to produce any
different side effects but again no data to state otherwise.
Remember if one person reports a side effect it has to be
documented. The best thing to do would be to ask your doctor and/or
pharmacist.
