Iopar SR 250mg (Acetazolamide) – Affordable Diamox Alternative
Iopar SR 250mg is used to decrease the elevated pressure in the eye. It is used to treat different kinds of glaucoma problems including open angle glaucoma, acute angle-closure glaucoma, and secondary glaucoma. It can be used alone or along with other medicine to control pressure within your eyes. The medicine is supplied in the form of tablets and can be purchased only on the prescription of a physician.
What is Iopar SR 250mg used for?
Iopar SR is used:
- To lower the intraocular pressure in the treatment of glaucoma.
- For the treatment of Edema due to heart failure
- For the management of acute altitude sickness
- As an adjunct to the treatment of refractory seizures
How does Iopar SR work?
Iopar SR contains the active component Acetazolamide which works by reducing the fluid pressure by decreasing formation of fluid within in the eye. It also works to increase the removal of water from the body by the kidney. In patients with epilepsy, the medicine block certain nerve damages that are responsible to cause seizures.
What medications interact with Iopar SR?
Inform your physician about the following medications:
- Aspirin
- Procainamide
- Tricyclic antidepressants

How should Iopar SR be used?
Take Lopar standard release tablets with a glass full of water. Carefully follow all the instructions of your physician. It is preferred to take on an empty stomach at least one hour before or one hour after consuming the food. Prefer taking it with food if stomach irritation occurs. Take your medicine at the prescribed intervals. Never take more than tablets than directed. Also, do not stop the treatment even if you feel better. Do not discontinue the treatment without discussing with your physician. If you think you have taken too much of this medicine, immediately contact your physician.
How long should you use Iopar SR?
Continue taking Lopar extended release tablets for as long as your physician recommends. Take your medicine at the same time each day as this will help you to remember to take it regularly. If you have trouble remembering your doses, ask your physician for some tips.
Missed dose of Iopar SR
If you have forgotten a dose of Iopar SR 250 mg tablets, take it as soon you remember and go back to your usual dosing schedule. If the time to take the next dose is near, leave the forgotten dose and take the next dose. Do not double up the dose to compensate the missed one
How should Iopar SR be stored?

What is Iopar SR 250mg and what does acetazolamide treat?
Iopar SR 250mg contains Acetazolamide 250mg (sustained-release), a systemic carbonic anhydrase inhibitor (CAI) used for several conditions including open-angle glaucoma, acute altitude sickness prevention and treatment, and as an adjunctive antiepileptic therapy. In glaucoma, acetazolamide reduces aqueous humor production. For altitude sickness, it accelerates acclimatisation by stimulating breathing. The SR (sustained-release) formulation provides a prolonged, more consistent drug effect compared to immediate-release acetazolamide tablets, and is the generic equivalent of Diamox SR.
How long does Iopar SR 250mg (acetazolamide) take to lower eye pressure in glaucoma?
Iopar SR 250mg (acetazolamide sustained-release) begins reducing intraocular pressure within 1 to 2 hours of ingestion. The SR formulation maintains IOP-lowering effect for up to 12 hours per dose. Steady-state IOP reduction is typically established within the first day of regular use. Iopar SR is usually prescribed twice daily (morning and evening) for glaucoma. It is particularly useful as adjunctive therapy when topical eye drops alone provide insufficient IOP control. Your ophthalmologist will monitor IOP response and adjust the regimen accordingly.
Is Iopar SR the same as Diamox SR? How do they compare?
Yes. Iopar SR 250mg contains the same active ingredient as Diamox SR — Acetazolamide 250mg in a sustained-release formulation — and is clinically bioequivalent. Both provide the same IOP-lowering and altitude sickness prevention effects. The primary difference is cost: Iopar SR is a significantly more affordable generic option. For patients requiring systemic carbonic anhydrase inhibition for glaucoma or altitude prophylaxis, Iopar SR 250mg provides the same proven outcomes as Diamox SR at lower cost.
What is the correct dosage of Iopar SR 250mg for glaucoma and altitude sickness?
For glaucoma: Iopar SR 250mg is typically taken once or twice daily (morning and evening). For altitude sickness prevention: 250mg taken twice daily, starting 1 to 2 days before ascent and continuing for 2 days after reaching altitude. For treatment of established altitude sickness: 250mg twice to three times daily until symptoms resolve. Doses should be taken with food to reduce gastrointestinal side effects. Do not crush or chew SR capsules — swallow whole to maintain sustained-release properties. Always follow your prescriber's specific dosing instructions.
What are the side effects of Iopar SR 250mg (acetazolamide)?
Common side effects of Iopar SR 250mg include paraesthesia (tingling in fingers and toes), frequent urination, altered taste (particularly with carbonated drinks), fatigue, loss of appetite, and gastrointestinal upset. Electrolyte imbalances — particularly low potassium (hypokalaemia) and metabolic acidosis — can occur with regular use. Serious but rare effects include sulfonamide-class hypersensitivity reactions and blood disorders. Acetazolamide should not be used in patients with sulfonamide allergy, severe renal or hepatic disease, or adrenal insufficiency.
Is Iopar SR 250mg safe for long-term glaucoma use?
Long-term use of Iopar SR 250mg (acetazolamide) for glaucoma requires monitoring of electrolytes (particularly potassium), kidney function, blood count, and liver enzymes. Metabolic acidosis, hypokalaemia, and nephrolithiasis (kidney stones) are concerns with prolonged use. Potassium supplementation is often required. Because of these monitoring requirements and side effect burden, oral acetazolamide is typically considered a second-line or adjunctive glaucoma treatment, used when topical agents alone are insufficient. Regular review with your ophthalmologist and primary care physician is essential.
Can Iopar SR 250mg be used to prevent altitude sickness during trekking?
Yes. Acetazolamide (Iopar SR 250mg) is an established, evidence-based prophylaxis and treatment for acute mountain sickness (AMS). It works by stimulating breathing, accelerating acclimatisation. Starting 1 to 2 days before ascent significantly reduces AMS incidence. It does not replace gradual acclimatisation and should be combined with a slow ascent schedule. Iopar SR is contraindicated in patients with sulfonamide allergy. Consult a travel medicine specialist before using acetazolamide for altitude trekking — dosing, timing, and individual suitability should be professionally assessed.
Iopar SR (acetazolamide) vs topical eye drops for glaucoma: When is oral CAI needed?
Topical carbonic anhydrase inhibitors (brinzolamide, dorzolamide) are generally preferred over oral acetazolamide (Iopar SR) for glaucoma due to the substantially lower systemic side effect burden of eye drops. Oral acetazolamide is reserved for acute angle-closure glaucoma crisis, severe open-angle glaucoma with inadequate IOP control on maximum topical therapy, or as a short-term bridge to surgery. The systemic side effects — paraesthesia, metabolic acidosis, frequent urination — make oral CAI less tolerable for long-term routine glaucoma management.
Who should not take Iopar SR 250mg (acetazolamide)?
Iopar SR 250mg is contraindicated in patients with sulfonamide hypersensitivity (risk of serious allergic reaction), severe renal or hepatic impairment, hyponatraemia, hypokalaemia, and Addison's disease. Long-term use is avoided in patients at high risk of nephrolithiasis (kidney stones). Caution is required in elderly patients, pregnant women (avoid in first trimester), and those taking other medications known to cause metabolic acidosis. Always disclose all medical conditions and medications to your doctor before starting Iopar SR.
Can Iopar SR 250mg be used as an antiepileptic medication?
Acetazolamide (Iopar SR) is used as an adjunctive antiepileptic in some treatment-resistant epilepsy cases — particularly catamenial epilepsy (seizures related to menstrual cycle) and certain childhood epilepsy syndromes. Its use for epilepsy has largely been superseded by newer antiepileptic drugs with better safety profiles. It is never a first-line antiepileptic. When used for epilepsy, the dose and monitoring requirements are similar to glaucoma use. A neurologist must supervise acetazolamide use for seizure management.
