What allergy immunotherapy costs
Two routes, two cost shapes: in-office injections concentrate the cost in repeat visits across years - copays, administration fees, and the travel and time around them - while at-home drops concentrate it in a recurring monthly charge. Which costs less depends far less on the headline price than on your coverage and how many years the course actually runs.
Why this is a multi-year number, not a monthly one
Immunotherapy is a desensitisation course measured in years, with a build-up phase followed by a longer maintenance phase. Any comparison that stops at the first month describes almost none of the commitment. Take the monthly figure, multiply by the number of months the service says a course runs, and compare those totals instead.
What insurance usually touches, and what it usually doesn't
Coverage commonly splits: the clinician consult and the allergy testing are the parts most often billed to insurance, while the preparation itself is frequently the cash item. An injection schedule tends to generate a copay per visit, which is where a high-frequency early phase adds up. Ask which line items are billed and which are not.
The costs that don't appear on the price page
An injection schedule means repeat trips to a clinic, often weekly at the start, each carrying travel and time away from work. An at-home route removes those but adds the discipline of near-daily dosing for years. Neither is free - they charge in different currencies, and both belong in the comparison.
Do the arithmetic before you sign up
Take the entry price, the ongoing monthly price, anything billed separately, and the realistic number of months, and multiply it out. There is a free tool on this site that does it: Cost Check - nothing you enter is sent anywhere.
Common questions
Is an at-home route always cheaper than injections? Not always. A well-covered injection schedule with a low copay can total less across several years than an uncovered monthly subscription, and the opposite is just as common. It depends on your plan and the course length, which is why the multi-year arithmetic decides this rather than the advertised monthly figure.
What does compounded mean here? A preparation mixed for one individual is compounded rather than dispensed as a standard product. Services should state this plainly. The FDA does not review or approve compounded preparations for safety or efficacy, and that is worth knowing before paying, independently of what it costs.
What should be published before I pay? The entry price and what it covers, the ongoing price, which items are billed to insurance, how long a course is expected to run, and the cancellation mechanism. Those five, published, describe a service you can actually evaluate.
