The card for the worst night.
When you're too sick to explain, this speaks for you. It tells the ER what's going on, asks them to check for other causes, and gives the doctor the facts, without picking a fight.
Hyperemesis Syndrome
I'm a heavy, long-term cannabis user with severe cyclic vomiting. My symptoms are relieved by hot showers, which is a known sign of CHS.
- Standard antiemetics (e.g. ondansetron) often underperform. Haloperidol, droperidol, or olanzapine plus topical capsaicin are the supported options.
- Please check electrolytes and consider an ECG first. Prolonged vomiting depletes potassium, low potassium prolongs QT, and the drugs above prolong it too.
- Not first-line: opioids and benzodiazepines. They may worsen it.
- Diagnosis of exclusion. Please rule out other causes.
Why it's written this way
A card that ordered specific drugs could make a busy team anchor on CHS and miss something dangerous, or read as drug-seeking and get ignored. This one does the opposite: it gives your history, names the one tell that helps them recognize CHS, and explicitly asks them to keep looking. It helps the doctor do their job, it doesn't try to do it for them.
