FAQs

Common questions

What makes a custom nasal spray different from Flonase or Nasacort?+
OTC sprays contain a single ingredient at a single strength. Custom compounding lets us combine multiple active ingredients — for example, an antihistamine + steroid + anti-inflammatory in one bottle — at strengths matched to your symptoms.
Where does the compounding happen?+
We partner with licensed 503A compounding pharmacies in the US. Once your formula is approved, the prescription is sent directly to the pharmacy and shipped to you — usually within 5–7 business days.
How much does the compounded medication cost?+
Compounded formulas typically run $40–$120 per month depending on ingredients. Most insurance plans don't cover compounded medications, but they're HSA/FSA eligible. You'll see the exact price before the order ships.
How long until I feel relief?+
Most patients notice improvement within 5–10 days of starting a well-targeted formula. If it's not working, the allergist will adjust the formulation at no extra cost during the 6-month follow-up window.
Can you refill my existing custom spray prescription?+
Yes — if you have a prior formula that works, we can review it and send a refill order to the compounding pharmacy. Upload your prior prescription during intake.
