Antiparasitic and Antihelminthic Medications
Key Points
- Antiparasitic medications treat infections caused by parasites.
- Antihelminthic medications are a subgroup used for worm (helminthic) infections.
- These therapies are distinct from antibiotics and should be selected by pathogen type.
Class Overview
Parasitic infections require targeted therapy aligned to organism class. Antiparasitic medications are used for non-worm parasitic infections, while antihelminthic agents are used when helminths (worms) are identified or strongly suspected.
Nursing Considerations
- Confirm likely pathogen category before medication administration.
- Reinforce full-course completion and follow-up testing when ordered.
- Monitor symptom trajectory and escalate persistent fever, dehydration, or worsening systemic signs.
