What should you know about giardiasis treatments at home?

Fluid loss can cause thirst, dry mouth, dizziness and reduced urination. Food tolerance may change temporarily, and [Bloating](/symptoms/bloating/) or [Abdominal Pain](/symptoms/abdominal-pain/) can accompany [Diarrhoea](/symptoms/diarrhoea/). Avoid alcohol and foods that clearly worsen symptoms. Do not rely on herbal remedies or leftover medicines to treat the parasite. See [Giardiasis](/conditions/giardiasis/) for the condition overview.

Keep fluids within reach and take small sips if nausea is present. Wash hands with soap after toilet use and before handling food; clean soiled bathroom surfaces and launder soiled clothing separately when practical. Avoid preparing food for others while diarrhoea continues. Book a [GP Consultation](/treatments/consultations-and-assessment/gp-consultation/) if symptoms persist or exposure was likely. Use prescribed [Antibiotic Treatment](/treatments/medical-management/antibiotic-treatment/) only as directed.

Seek urgent care for inability to drink, repeated vomiting, faintness, confusion, very little urine, blood in stools or severe abdominal pain. Contact a clinician sooner for a child, older adult, pregnancy, or reduced immunity. Persistent diarrhoea can require testing, prescription medicine and a plan to replace lost fluids.

Ask which rehydration drink is suitable, what foods to pause, whether you need stool testing, and how long to use extra hygiene measures. Confirm which symptoms mean you should return for review.
