Important information about Neptazane

The active ingredient in Neptazane is methazolamide. It belongs to the drug class called carbonic anhydrase inhibitors. Neptazane reduces intraocular pressure by decreasing the production of aqueous humor (eye fluid). This prevents fluid buildup and lowers the pressure within the eye.

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using Neptazane. However, the following is a synopsis of the general guidelines for the use of Neptazane:

You can take this medication with or without food. If it upsets your stomach, try taking it with food.

Some mild or common side effects of Neptazane include:

  • Tingling or the feeling of "pins and needles" in your arms and legs (paresthesia).
  • Loss of appetite.
  • Drowsiness.
  • Nausea.
  • Vomiting.
  • Ringing in your ears.

Some individuals may experience serious side effects while using Neptazane. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

  • Severe allergic reaction presenting with swelling of the face, lips, tongue, or throat, hives, and trouble breathing.
  • Severe skin rash (Stevens-Johnson syndrome) presenting with bright red peeling skin.
  • Symptoms of anemia (low red blood cell count) like fatigue, pale skin, and shortness of breath.
  • Signs of a kidney stone such as pain in your lower back, blood in your urine, and painful or difficult urination.

These are not all of the possible side effects of Neptazane. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

Before starting Neptazane, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including:

  • Emphysema or other breathing problems.
  • Diabetes.
  • Liver or kidney disease.
  • Glaucoma.
  • Electrolyte imbalances.
  • Adrenal gland problems.

  • History of serious hypersensitivity reaction to methazolamide or sulfonamides (sulfa drugs).
  • Chronic angle-closure glaucoma.
  • Adrenal gland failure.
  • Severe liver problems (hepatic insufficiency).
  • Severe kidney problems.
  • Electrolyte imbalances such as hyperchloremic acidosis, low potassium (hypokalemia), or low sodium (hyponatremia).

Neptazane begins working within a few hours of taking a dose.

When Neptazane is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking to avoid any negative drug interactions, including:

  • When combined with methenamine, Neptazane may decrease its effects.
  • When combined with salicylates (including high-dose aspirin), you may experience more severe side effects from Neptazane.
  • Other carbonic anhydrase inhibitors, such as acetazolamide, may cause more severe side effects when combined with methazolamide.

Neptazane is available as a 25 mg or 50mg tablet.

It should be stored at room temperature out of the reach of children or pets.

It is manufactured by Storz.

Yes, it is available from many manufacturers of generic versions of brand-name Neptazane.

Barring any serious side effects as listed above, or under the direction of a physician, you should not stop using methazolamide suddenly.
