A Nurse Is Preparing To Administer Famotidine 20 Mg

When a nurse prepares to administer famotidine 20 mg, precision and patient safety are paramount. This article dives deep into the intricacies of this common nursing task, providing a comprehensive guide for healthcare professionals.

Famotidine: An Overview

Famotidine, commonly known by its brand name Pepcid, is a histamine H2 receptor antagonist. It functions by reducing the amount of acid produced in the stomach. This makes it a crucial medication for treating conditions such as:

• Peptic Ulcers: Sores in the lining of the stomach or duodenum.
• Gastroesophageal Reflux Disease (GERD): A condition where stomach acid frequently flows back into the esophagus.
• Zollinger-Ellison Syndrome: A rare condition causing excessive stomach acid production.
• Erosive Esophagitis: Inflammation and damage to the esophagus due to acid reflux.
• Prevention of Stress Ulcers: Particularly in hospitalized patients.

Understanding the mechanism and indications of famotidine is the first step in ensuring its safe and effective administration. Nurses need to be familiar with the drug's action, potential side effects, and interactions to provide optimal patient care.

  • For tablets, provide the tablet with a glass of water. Ensure the patient swallows the tablet completely.
  • For oral suspension, use a calibrated oral syringe to measure the correct dose. Administer the suspension slowly, allowing the patient to swallow it gradually.
• Post-Administration:
  • Ensure the patient remains upright for at least 30 minutes after taking the medication to prevent acid reflux.
  • Instruct the patient to avoid lying down immediately after taking the medication.

2. Intravenous (IV) Administration

• Preparation:
  • Verify the patency of the IV site before administering the medication.
  • Ensure the IV solution is compatible with famotidine.
• Administration:
  • Administer the diluted famotidine solution slowly over a period of 15-30 minutes, as prescribed by the physician.
  • Monitor the patient closely for any signs of adverse reactions during the infusion, such as flushing, itching, or difficulty breathing.
• Post-Administration:
  • Flush the IV line with normal saline after administering the medication.
  • Monitor the patient for any delayed adverse reactions.

Monitoring and Assessing After Administration

Following the administration of famotidine 20 mg, continuous monitoring and assessment are essential to evaluate the medication's effectiveness and identify any potential adverse effects.

1. Therapeutic Effects

• Symptom Relief: Assess the patient's symptoms to determine if the medication is providing relief. This includes monitoring the frequency and severity of heartburn, acid reflux, and stomach pain.
• Gastric pH: In some cases, gastric pH monitoring may be necessary to evaluate the effectiveness of famotidine in reducing stomach acid production.
