DOSAGE AND ADMINISTRATION
The initial dose of the drug is 1 drop of 0.25% solution twice a day. If the clinical response is not adequate, the dosage may be changed to one drop of 0.5% solution twice a day. Since stabilization of intraocular pressure after initiation of therapy occurs within a few weeks, treatment effect is evaluated after 4 weeks. Starting a patient on timolol who previously received topical therapy with other beta-blocker should be done next day following administration of appropriate daily dose of the latter. The initial dose is 1 drop of 0.25% solution two times a day into affected eye. If there is no adequate effect the dose may be increased till 1 drop of 0.5% solution 2 times a day. Monotherapy with one topical antiglaucomal agent not related to beta-blockers group should be added by prescription of timolol. The dose is 1 drop of 0.25% solution in affected eye 2 times a day. Next day previously applied antiglaucomal agent is withdrawn and then the treatment is continued with timolol. If required the dose of timolol may be increased till 1 drop of 0.5% solution 2 times a day.
If a patient wears soft contact lenses he should not apply Normatin eye drops since Normatin contains a preservative, which may be absorbed by contact lenses and has unfavorable effects on eye tissues. Hard contact lenses should be removed immediately prior to administration of Normatin and reinserted 15 minutes following application.
