Side-by-side comparison of diazoxide and glimepiride. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.

minor Known Drug Interaction

The following are examples of medications that may reduce the glucose-lowering effect of sulfonylureas including glimepiride, leading to worsening glycemic control: danazol, glucagon, somatropin, protease inhibitors, atypical antipsychotic medications (e.g., olanzapine and clozapine), barbiturates, diazoxide, laxatives, rifampin, thiazides and other diuretics, corticosteroids, phenothiazines, thyroid hormones, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics (e.g., epinephrine, albuterol, terbutaline), and isoniazid.

Summary
diazoxide

VYKAT XR is a medicine used to treat excessive hunger in people with Prader-Willi syndrome. It helps to control their appetite.

What It Treats
diazoxide

VYKAT XR treats hyperphagia (excessive hunger) in people aged 4 years and older who have Prader-Willi syndrome (PWS). PWS is a genetic disorder that can cause constant hunger. This medicine helps manage the strong urge to overeat.

glimepiride

Glimepiride is used to help control blood sugar levels in adults with type 2 diabetes. It should be used with a healthy diet and regular exercise. This medicine will not work for type 1 diabetes or diabetic ketoacidosis.

How It Works
diazoxide

VYKAT XR contains diazoxide choline. It is thought to work by affecting how insulin is released in the body. This helps to reduce hunger.

glimepiride

Glimepiride helps your body release more insulin. Insulin helps move sugar from your blood into your cells for energy. This lowers your blood sugar levels.

How to Read This diazoxide vs glimepiride Comparison

diazoxide is classified in the Potassium Channel Opener (Hyperinsulinism) drug class, while glimepiride sits within the Sulfonylurea class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, diazoxide has 235 submissions while glimepiride has 10,881. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to diazoxide can cause blood sugar to rise, which prevents glimepiride from working as well as it should.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.

A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
