Carbastat is used to treat glaucoma and is given during ophthalmic surgeries. The medication is available as an eye drop and works by eliminating the pressure to the eyes of patients with glaucoma. Carbastat can also be helpful in narrowing the pupils of the eyes during cataract surgery.

Carbastat or Carbamylcholine is a cholinergic medication distributed under the brand names Miostat, Isopto Carbastat and Carboptic. It is used to treat patients with eye conditions like glaucoma and during eye surgery. Carbastat is a prescribed medication and can only be used by patients who have been given a prescription by their doctor.

This medication is administered to the eyes through intraocular solution, or an eye drop. It is best to wash your hands before administering the medication to avoid infections.

When administering the eye drops, tilt your head backwards and gently pull the lower eyelid downwards. Position the dropper just above the eye. The dosage is determined by the doctor and is based on the patient’s condition. Squeeze the dropper for a drop of the medication then gently close the eye. If more drops are required, repeat the procedure in five-minute intervals.

Common side effects due to Carbastat usage include teary eyes, stinging or burning sensation, sweating, headache, dizziness, nausea and low vision. Though rare, retinal detachment may occur in some patients and can lead to blindness. If any of these side effects occur, seek medical attention quickly. Before using Carbastat, consult with your doctor and undergo a thorough check up of your retina to determine if there is a risk of retinal detachment.

Avoid touching the dropper to avoid infection in the eyes. When administering the medication, put a little pressure to the innermost corner of the eye after each drop.

Carbastat may affect vision at night so it is advised to refrain from driving, sports or operating a machine.

If you wear contact lenses, remove them before administering Carbastat. Consult your doctor to determine if it is safe to use contact lenses after the medication has been administered. Patients should be aware that some of the preservatives in Carbastat can cause a discoloration of the contact lenses.

If you are using other eye medication like suprofen, flurbipron ketorolac and diclofenac, inform your doctor prior to the use of Carbastat. This is necessary since some medications may react negatively when taken with Carbastat.

Because this medication is used in the eyes, never use the medication when you notice discoloration or particles in the medication to avoid risking your eyesight. If you notice either of these conditions, take the medicine to the doctor to check.
