Usage Guidelines
Take orally with water, with or after meals. Take the final dose of the day in the afternoon to prevent insomnia. Taper gradually when discontinuing.
General Administration Advice: Adhere strictly to the prescribed dosage, frequency, and treatment course. For oral medications, swallow with sufficient water. Never stop antibiotics, psychiatric medications, or antihypertensives abruptly without clinical direction.
Possible Side Effects
Common: Nausea, dizziness, insomnia, livedo reticularis (purplish net-like skin discoloration on legs), peripheral edema, orthostatic hypotension. Rare/Severe: Hallucinations, delirium, congestive heart failure, corneal edema, and neuroleptic malignant syndrome-like reaction upon abrupt cessation.
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Do not discontinue abruptly, as sudden withdrawal can precipitate acute parkinsonian crisis or neuroleptic malignant syndrome. Caution in heart failure, renal impairment, and psychiatric illness. Livedo reticularis is benign and reversible upon drug cessation.
