Increase fluid intake during illness, heat exposure, or exercise
Medications to avoid
No estrogen-containing contraceptive pills — speak to your doctor about alternatives
Avoid NSAIDs unless approved by your doctor — increase bleeding risk with anticoagulants
No new medications without checking with your doctor first
Warning signs — return to emergency department immediately for
Sudden severe headache — worst headache of your life
New weakness of arm, leg, or face
Sudden difficulty speaking or understanding speech
New seizure or shaking
Sudden vision changes or loss of vision
Confusion or unusual behavior
Unusual bleeding — blood in stool or urine, prolonged nosebleed, unusual bruising
Follow-up appointments
Neurology within 1 to 2 weeks after discharge

Repeat brain scan at 3 to 6 months — to check if clot has cleared
Ophthalmology if you had swelling behind your eyes
Hematology if blood clotting tests are pending
