Letter to his patients: one spray four times a day
- Dose
- “one spray”
- How often
- “four times a day”
- How taken
- “nasal spray”
“When all three of these criteria are met and patient has adequate understanding of what VIP can do, then the patient can begin treatment with one spray four times a day. […] Further titration of dosing either up or down is only done after consultation with me.”
Context: Instructions to his own patients with CIRS. The criteria are a normal visual contrast sensitivity test, a low mould index at home and a negative nasal culture. He also asks for lipase blood tests after one month. The letter does not state the amount per spray; his published papers describe 50 mcg per spray.
