Penicillin V, also known as penicillin V potassium, is a narrow-spectrum antibiotic commonly prescribed for infections caused by susceptible gram-positive bacteria, such as streptococcal pharyngitis. Nurses play a vital role in ensuring its safe administration and monitoring its effects. This guide outlines key nursing responsibilities to optimize patient outcomes.

Introduction to Penicillin V
Penicillin V is effective against mild to moderate bacterial infections, including:
- Streptococcal pharyngitis (strep throat)
- Sinusitis
- Otitis media
- Prophylaxis for rheumatic fever and certain dental procedures
It works by inhibiting bacterial cell wall synthesis, making it bactericidal against susceptible organisms.
Nursing Considerations
Assessment
Before administering penicillin V, perform a detailed patient assessment:
- Allergy Screening: Confirm no history of penicillin or cephalosporin allergies due to potential cross-reactivity.
- Medical History: Assess for renal impairment or conditions affecting drug clearance.
- Medication Review: Check for interactions with drugs like probenecid, oral contraceptives, or anticoagulants.
- Baseline Infection: Document symptoms (e.g., fever, sore throat) to monitor treatment efficacy.
Administration
Follow these guidelines for safe administration:
- Dosage: Typically 250-500 mg every 6-8 hours, adjusted per infection severity and provider orders.
- Forms: Available as tablets or oral suspension; verify the prescribed form.
- Timing: Administer on an empty stomach (1 hour before or 2 hours after meals) to enhance absorption.
- Technique: For oral suspension, shake well and measure accurately with a dosing device.
Monitoring
Monitor patients closely during therapy:
- Allergic Reactions: Look for rash, itching, swelling, or anaphylaxis symptoms (e.g., difficulty breathing).
- Side Effects: Note gastrointestinal issues (nausea, diarrhea) or signs of superinfection (e.g., oral thrush).
- Response: Track symptom improvement to assess therapeutic effectiveness.
Patient Education
Provide clear instructions to ensure adherence and safety:
- Full Course: Emphasize completing the entire prescription, even if symptoms resolve early, to prevent resistance.
- Side Effects: Explain common effects (e.g., mild diarrhea) and when to report severe reactions (e.g., rash, breathing issues).
- Diet: Advise taking on an empty stomach and avoiding acidic beverages (e.g., orange juice) that may reduce absorption.
Evaluation
Evaluate treatment success at the end of therapy:
- Symptom Relief: Confirm resolution of infection signs (e.g., reduced fever, improved throat pain).
- Lab Confirmation: Review culture results, if available, to verify bacterial eradication.
- Follow-Up: Arrange follow-up visits as needed to ensure complete recovery.
Management of Adverse Effects
Be prepared to address potential complications:
- Mild Allergic Reactions: Administer antihistamines per protocol for rashes or itching.
- Severe Allergic Reactions: For anaphylaxis, provide epinephrine and oxygen, and seek immediate medical support.
- Superinfections: Watch for new symptoms (e.g., persistent fever, vaginal yeast infection) and report to the provider.
- GI Upset: If nausea is severe, consult the provider about adjusting administration (e.g., with a small amount of food).
Conclusion
Penicillin V is a cornerstone antibiotic requiring careful nursing management. By conducting thorough assessments, adhering to administration protocols, monitoring for adverse effects, educating patients, and evaluating outcomes, nurses can ensure safe and effective treatment of bacterial infections.
