acetaZOLAMIDE ER

Acetazolamide ER is FDA-approved for several conditions, including:

• Glaucoma: To lower intraocular pressure and prevent damage to the optic nerve.
• Seizures: As an adjunct treatment for certain types of seizures, particularly absence seizures.
• Altitude Sickness: To prevent and reduce the severity of symptoms related to acute mountain sickness.
• Edema: To reduce fluid retention associated with conditions like congestive heart failure and drug-induced edema.

Off-label uses may include the treatment of periodic paralysis and certain metabolic disorders, though these should be discussed with a healthcare provider.

Acetazolamide ER should not be used in individuals who have:

• A known hypersensitivity to acetazolamide or sulfonamides.
• Severe liver or kidney disease.
• Adrenal gland failure (Addison's disease).
• Hyperchloremic acidosis (an electrolyte imbalance).

It should also be used with caution in patients with electrolyte imbalances, respiratory acidosis, or a history of kidney stones.

When taking acetazolamide ER, it is important to follow your healthcare provider’s instructions closely. Take the medication with food if it causes stomach upset, and make sure to stay hydrated to reduce the risk of kidney stones. Avoid alcohol, as it can increase side effects like dizziness and drowsiness. If you are taking acetazolamide ER for altitude sickness, start taking it before your ascent as directed by your provider. Monitor for signs of unusual tiredness, muscle cramps, or tingling in the hands or feet, and report these to your healthcare provider.

Common side effects of acetazolamide ER include nausea, vomiting, diarrhea, dizziness, fatigue, and a metallic taste in the mouth. More serious side effects, though less common, can include electrolyte imbalances, kidney stones, and severe allergic reactions. If you experience symptoms such as severe rash, difficulty breathing, or signs of liver or kidney issues (e.g., yellowing of the skin or eyes, dark urine), seek medical attention immediately.

The major risks associated with acetazolamide ER include the potential for electrolyte imbalances, which can lead to symptoms like muscle weakness, confusion, or irregular heartbeats. Patients should be monitored for signs of metabolic acidosis, particularly those with respiratory or renal conditions. Acetazolamide ER may also increase the risk of kidney stones, so it’s important to stay hydrated. This medication may impair your ability to perform tasks that require alertness, so use caution when driving or operating machinery.

Acetazolamide ER can interact with other medications, including:

• Aspirin: High doses can increase the risk of acidosis.
• Other diuretics: May increase the risk of electrolyte imbalances.
• Anticonvulsants: May increase or decrease the effects of other seizure medications.
• Lithium: May reduce the effectiveness of lithium.

It is important to inform your healthcare provider of all medications, supplements, and herbal products you are taking to avoid potential interactions.

Alternative medications to acetazolamide ER depend on the condition being treated:

• Glaucoma: Other options include beta-blockers (e.g., timolol), prostaglandin analogs (e.g., latanoprost), and other carbonic anhydrase inhibitors (e.g., dorzolamide).
• Seizures: Alternatives include other anticonvulsants like valproate or lamotrigine.
• Edema: Other diuretics such as furosemide or hydrochlorothiazide may be considered.
• Altitude Sickness: Dexamethasone and other preventive measures can be used.

Discuss with your healthcare provider to determine the best alternative based on your specific needs.
