Alphagan
Alphagan is the only alpha agonist to be licensed for long term anti glaucoma therapy. It works by reducing the production of aqueous humour by the ciliary body and it may also help improve the outflow of aqueous humour from the eye.
Alphagan is usually prescribed two or three times daily.
The systemic side effects of Alphagan include a dry mouth and a feeling of being generally unwell. It can also cause depression in susceptible people. Alphagan is known to cause nightmares in children and should not be prescribed for infants.
These side effects are relatively rare and most people are able to use these drops without any significant ill effect, however, as with all eye drops, it is wise to practice punctal occlusion (blocking the tear duct) after taking the drops in order to minimise the risk of systemic side effects.
It is not uncommon for about 30% of patients to develop an allergic reaction to Alphagan after a prolonger period of successful use. This allergy results in very red puffy eyes and considerable irritation. Should this happen to you, consult your family doctor or ophthalmologist.
