How does Labetalol injection work?

Labetalol injection is used to treat severe hypertension (high blood pressure). High blood pressure causes the arteries and heart to work harder. If it persists for an extended period, the arteries and heart may cease functioning correctly. This can cause damage to the blood arteries in the heart, brain, and kidneys, leading to a stroke, kidney problems, or heart failure. Hypertension may also raise the likelihood of having a heart attack. Controlling blood pressure can make specific issues less prevalent.

This medication is classified as a beta-blocker. It influences the response to nerve signals in specific regions of the body, such as the heart. As a response, the heartbeat slows, and the blood pressure drops. When blood pressure is reduced, the proportion of oxygen and blood delivered to the heart increases. This can assist in reducing the number of strokes and heart attacks.

The Labetalol injection includes the following salt compositions:

  • Sodium Chloride.
  • 5% Dextrose Intravenous Infusion BP or Dextrose Injection BP.

  • 1. Missed Dose: Take the medication as soon as possible, but forgo the skipped dosage if the next dosage is approaching.
  • 2. Overdose: If you overdose, get immediate medical treatment. Slow heart rate, wheezing, chest tightness, difficulty breathing, acute dizziness, seizure, or fainting are all indications of an overdose.
