Write the comparison page nobody else will
Ketamine infusion and Spravato are different products with different rules, and the person searching does not know that. Infusion clinics use generic ketamine off label, mostly cash pay, with no REMS. Spravato is FDA approved for specific indications, dispensed through a restricted program, and covered by many payers. Those are opposite buying decisions.
Most Spravato centers have a services page that mentions esketamine once and never names the distinction. That page loses to whichever local infusion clinic wrote a real comparison. Written straight, including what Spravato is not good for, the comparison page is usually the page that produces the calls.
It also filters. A patient who reads the two-hour monitoring requirement and the no-driving rule before calling is a patient who shows up for the second dose.
