Effectiveness

How Methazolamide Affects Patients

Methazolamide is a medicine used to lower pressure in the eye for people with glaucoma or high eye pressure who don't respond well to other treatments. It is not an antibiotic and does not work as an anticonvulsant. Taking this drug will also increase the amount of urine produced, and also lead to the excretion of sodium, potassium, and chloride.

How Methazolamide works in the body

Methazolamide works by blocking carbonic anhydrase, a molecule that helps produce bicarbonate ions. By stopping this process, it decreases the production of aqueous humor, a fluid in the eyes. This reduces sodium and fluid transport in the eye.

Methazolamide for High Eye Pressure or Glaucoma that May Worsen without Treatment

This medication was my last resort for treating high eye pressure. It did help lower the pressure, but I felt really tired and had no energy to do anything. Also, it made me so sleepy that I just dozed off many times while watching TV.

Methazolamide for High Eye Pressure or Glaucoma that May Worsen without Treatment

After only one week of using this medication, my blood pressure has lowered significantly. I have noticed that I tend to feel tired after taking it and often fall asleep in front of the TV; however, this is much better than losing my vision.

Methazolamide for High Eye Pressure or Glaucoma that May Worsen without Treatment

I've been taking Methazolamid for several years and I know that w/o my eye pressure would be a lot worse, like it used to be before, with only eye drops Cosopt, Alphagan, Lumingan. Unfortunately, the big side effect to this medication is that I feel very sleepy, very tired to the point that I don't have energy to do finish what I'm doing many times.
