Labetalolo S.A.L.F. (Labetalol Hydrochloride)

Labetalolo S.A.L.F. acts on the cardiovascular system to lower elevated blood pressure.

• Hypertension: lowers systemic blood pressure by decreasing peripheral vascular resistance and cardiac output.
• Hypertensive emergencies: provides rapid blood pressure reduction in acute, life‑threatening situations.
• Angina pectoris: helps relieve chest pain by reducing myocardial oxygen demand through combined alpha‑ and beta‑blockade.

• Labetalol blocks alpha‑1 adrenergic receptors and non‑selective beta‑adrenergic receptors, resulting in vasodilation and reduced heart rate and contractility. This dual antagonism decreases peripheral vascular resistance and cardiac output, leading to a net reduction in arterial blood pressure.

Labetalolo S.A.L.F. may cause a range of adverse reactions.

Common Side Effects

• Dizziness: feeling light‑headed or unsteady.
• Fatigue: unusual tiredness or lack of energy.
• Headache: mild to moderate head pain.
• Nausea: upset stomach or urge to vomit.
• Flushing: warmth and redness of the face or neck.
• Nasal congestion: blocked or runny nose.

Serious or Rare Side Effects

• Severe hypotension: dangerously low blood pressure requiring medical attention.
• Bronchospasm: narrowing of the airways, especially in patients with asthma.
• Hepatic dysfunction: abnormal liver enzyme elevations.
• Cardiac block: impaired electrical conduction of the heart.
• Arrhythmias: irregular heart rhythms that may be life‑threatening.
• Stevens‑Johnson syndrome: severe skin reaction with blistering.

Before using Labetalolo S.A.L.F., consider the following precautions.

• Monitor blood pressure: avoid excessive drops that could cause dizziness or syncope.
• Assess cardiac function: use cautiously in patients with heart failure or conduction disorders.
• Check respiratory status: avoid in patients with active asthma or severe chronic obstructive pulmonary disease.
• Review hepatic function: dose adjustment may be needed in liver impairment.
• Avoid abrupt discontinuation: taper under medical supervision to prevent rebound hypertension.
• Store below 25°C: keep in original container, protect from light and moisture.

Labetalolo S.A.L.F. can interact with several medicines.

Major Interactions (Avoid)

• Combined use with other antihypertensives (e.g., ACE inhibitors, diuretics) may cause severe hypotension.
• Concomitant beta‑agonists (e.g., albuterol) may reduce bronchodilator effectiveness.
• Co‑administration with calcium‑channel blockers (e.g., verapamil) may increase risk of bradycardia.

Moderate Interactions (Monitor Closely)

• NSAIDs may blunt the antihypertensive effect of labetalol.
• Clonidine may cause rebound hypertension if stopped abruptly while on labetalol.
• Insulin or oral hypoglycemics may have altered glucose control when combined with labetalol.
