Ocular and systemic side effects of brimonidine 0.2% eye drops (Alphagan) in children
Bowman RJ; Cope J; Nischal KKEye 2004; 18: 24-26
INTRODUCTION: Brimonidine 0.2% (Alphagan) is a topical alpha-2 agonist widely used as an antihypertensive. There have been occasional reports of systemic adverse effects in children including apparent central nervous system depression. There are few data available on the overall safety of brimonidine 0.2% in children. METHODS: Computerized pharmacy records were used to identify all children who had been prescribed brimonidine 0.2% in the authors' eye department between August 1999 and June 2001, and their notes were reviewed. RESULTS: In all, 23 patients were identified from pharmacy records and 22 sets of notes were recovered and reviewed. The mean age at commencement of treatment was eight years (range, 0-14 years). In all, ten (46%) were treated in one eye and 12 (54%) in both. Brimonidine 0.2% was taken for a mean 14 months (range, one day-75 months). A total of 14 (64%) patients were already taking a topical beta-blocker when brimonidine 0.2% was commenced and a further four (18%) were being treated with another topical hypotensive agent. Of the 22 patients, six (27%) had to stop brimonidine 0.2% because of adverse side effects (two because of local irritation/allergy, two because of tiredness, and two because of fainting attacks). DISCUSSION: Many topical hypotensive agents are not licensed for use in children and few safety data are available. In this study, 18% of children had systemic adverse effects sufficient to necessitate stopping the drug. It is possible that educational impairment may have passed unnoticed in others. Larger studies are required to investigate this further.
