Hello, Welcome to Pearl.com
Are you available for chat?
Are you wanting to know about the side effects of this eye drops?
The dosage of this eye drops is 1 drop twice a day. I guess the dose given is right.
Is the patient also put on any other anti-glaucoma eye medicine?
Ok. Alphagan is to be used as twice a day eyedrops only.
Its side effects are minimal such as ocular side effects such as redness/itching sensation/eye discomfort.Being an alpha agonist it can get absorbed into the systemic circulation and have effect on the cardiovascular system ( very rare consequences, not seen in otherwise healthy individuals).
But the side effects would be related to the eye medicine itself and not because of excessive dosage.
