## Primary Indications
* Severe hypertension unresponsive to other agents.
* Hypertensive emergencies.
## Adult Dosing
* **Initial Infusion:** 5-10 mcg/kg/minute.
* **Titration:** Increase by 5-10 mcg/kg/minute every 5-10 minutes until desired blood pressure reduction is achieved or a maximum dose of 100 mcg/kg/minute is reached.
* **Maintenance:** Titrate to maintain desired blood pressure.
## Pediatric Dosing
* **Initial Infusion:** 1-2 mcg/kg/minute.
* **Titration:** Increase by 1 mcg/kg/minute every 5-10 minutes as needed.
* **Maximum Dose:** Not well-established; use with extreme caution and close monitoring.
## Dose Adjustments
* **Renal Impairment:** No specific dose adjustment recommended, but caution and close monitoring are advised due to potential for accumulation.
* **Hepatic Impairment:** No specific dose adjustment recommended, but caution and close monitoring are advised.
## Contraindications
* Known hypersensitivity to the drug.
* Advanced aortic stenosis.
## Adverse Effects
* **Common:** Headache, flushing, reflex tachycardia, nausea, vomiting.
* **Serious:** Profound hypotension, myocardial ischemia, methemoglobinemia (rare).
## Key Drug Interactions
* **Other antihypertensives:** Additive hypotensive effects; increased risk of severe hypotension.
* **Anesthetics:** May potentiate hypotensive effects.
## Monitoring
* Continuous blood pressure monitoring (arterial line preferred for rapid titration).
* Heart rate.
* Renal function.
* Electrolytes.
* Methemoglobin levels if clinically suspected.
## Clinical Pearls
* Due to its potent vasodilatory effects, Mega%252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252525252520cv should be administered via continuous infusion with frequent titration based on hemodynamic response.
* Have a beta-blocker readily available to manage reflex tachycardia if necessary.
* Be prepared to manage profound hypotension if it occurs.
