Methazolamide Uses 

This medication is an antiglaucoma potent carbonic anhydrase inhibitor prescribed to treat chronic open-angle glaucoma and secondary glaucoma. It inhibits carbonic anhydrase in the ciliary process to decrease aqueous humor secretion by slowing the formation of bicarbonate with a reduction of sodium and fluid transport.  

Open-angle glaucoma is a condition in the eyes where the optic nerves are damaged, which affects the vision caused by high pressure in the eyes; left untreated may lead to blindness. This medication works by decreasing fluid production in the eyes; it is also prescribed to patients who need to lower IOP intraocular pressure in the eye before surgery. 

Methazolamide Interactions  

This medication can be used alone or be prescribed with other medicine; before taking it, be sure to tell your doctor the other medicines you are taking for it may interact with the following: aspirin, methenamine, cyclosporine, primidone, diflunisal, and other salicylate and supplements. Take note that these are not the complete lists, discuss them with your doctor. 

Methazolamide Dosage 

This is a prescription drug based on the medical condition, other taken medicine, and response to the treatment. Methazolamide 50 mg strength is available, usually prescribed as 50 to 100mg two to three times a day; it may be taken with food if stomach upset occurs. Regular intake will help attain the most benefit; try taking it at the same time of day every day. If a dose is missed, take it as soon as remembered, but if it’s almost the time of the following intake schedule, letting it be missed for double dosing is discouraged. 

Other oral medications can be prescribed for glaucoma if this medication doesn’t suit you. An eye drop is the usual initial prescription when treating glaucoma, but some eye drops are absorbed by the bloodstream causing unrelated side effects in the eyes. Other Methazolamide alternatives are laser therapy, filtering surgery, drainage tube, and MIGS minimally invasive glaucoma surgery.

Methazolamide VS Acetazolamide 

Both medicines are carbonic anhydrase inhibitors used in treating glaucoma. Still, Acetazolamide can also treat mountain sickness or altitude sickness and can be a part of the treatment plan for seizure and congestive heart failure. Methazolamide is prescribed at 50 to 100mg taken 2 to 3 times a day, while Acetazolamide is 500-1000mg twice a day in a divided dose. Methazolamide has fewer side effects than Acetazolamide, but it is also a weaker drug; Acetazolamide is prescribed in higher doses causing tingling and gastrointestinal upset. Studies show that Methazolamide is used more often than Acetazolamide, for it is more effective and is readily available. Both medicines are effective, but your doctor will help you decide which treatment is best for your condition.
