Another class of medications for glaucoma includes adrenergic agonists, such as epinephrine. These medicines also increase aqueous humor drainage.
Possible side effects of adrenergic agonists may include:
- Allergic reactions
- Blurred vision
- Increased heart rate.
Carbonic Anhydrase Inhibitors
Carbonic anhydrase inhibitor tablets, like beta-blockers, decrease production of aqueous fluid, but these medications seem to provoke more prominent side effects in some people.
Possible side effects of these medications may include:
The FDA's approval of a carbonic anhydrase inhibitor in eye drop form (Trusopt® [dorzolamide]) provides a glaucoma medication that may have fewer and reduced incidence of these prominent side effects.
Since reactions to glaucoma medications vary so much from person to person, a drug that can cause problems in one individual may easily be tolerated by another. An appropriate drug regimen, therefore, needs to be worked out carefully between the patient and the eye care professional.
Medications used to treat glaucoma are potent drugs. Those who take them should consult a pharmacist or their healthcare providers to be certain that they won't interact adversely with any other prescriptions or over-the-counter drugs being taken. For example, some over-the-counter products, including decongestants, may not be suited for people at risk of glaucoma.
