Complete the full 7-day course even if feeling better
Doxycycline: take with a full glass of water, stay upright for 30 minutes
Rest and hydration
Drink plenty of fluids daily
Avoid strenuous activity until fully recovered
Avoid alcohol during recovery
Alcohol worsens liver stress during leptospirosis recovery
Return to Emergency immediately for any of these warning signs
Yellowing of the skin or eyes (jaundice)
New or worsening
Decreased urine output or no urine for more than 8 hours
Dark brown or cola-colored urine
Coughing up blood or blood-tinged sputum
Worsening shortness of breath or difficulty breathing at rest
Confusion, severe headache with neck stiffness
Bleeding from any site
Gums, nose, skin bruising
Fever returning after initially improving
Persistent vomiting preventing fluid intake
Follow-up instructions
Return to clinic or family doctor within 48-72 hours
Blood tests will be repeated to monitor kidneys and blood counts
Specialist blood test at 2-3 weeks
Confirms the diagnosis of leptospirosis
Ophthalmology referral if eye symptoms develop weeks later
Uveitis can occur as a delayed complication
Preventing future exposure
Wear waterproof boots and gloves in occupational settings
Avoid wading or swimming in floodwater or unknown freshwater sources
Report exposure and control rodent populations in home or workplace
Inform household contacts of exposure history if clustering occurs
