Standard dosing: One 180 mg extended-release pill taken once daily, preferably in the morning with a glass of water.
Special populations:
Renal impairment: No dose adjustment is typically required unless severe.
Hepatic impairment: Start with a lower dose (e.g., 120 mg) and titrate cautiously.
Elderly: Begin with the lowest effective dose and monitor heart rate and blood pressure closely.
Administration notes: Do not split, chew, or crush the capsule - it is designed to release the drug slowly. If a dose is missed, take it as soon as remembered unless it is close to the next scheduled dose; do not double-dose.
Overdose: Symptoms may include severe hypotension, bradycardia, and heart block. Seek emergency medical care; treatment focuses on supportive measures and, if needed, intravenous calcium gluconate.
Discontinuation: Sudden cessation is generally safe, but patients with angina should be monitored for rebound chest pain. Tapering is rarely required for the extended-release formulation.
Patients should report any new symptoms such as faintness, palpitations, or swelling promptly.
