Allergy drops vs allergy shots

Both are effective. Separate Cochrane reviews found both routes effective for allergic rhinitis versus placebo: 51 trials for shots (Calderón 2007) and 60 trials for sublingual immunotherapy (Radulovic 2010). The most rigorous comparison between them, Dretzke and colleagues’ 2013 indirect comparison in the Journal of Allergy and Clinical Immunology, found no conclusive difference. The American Academy of Otolaryngology includes allergy drops in the standard of care, and drops are the standard of care in many EU countries.

Drops carry a lower risk of systemic reactions. Shots are given in a clinic with a 30-minute observation period precisely because systemic reactions, though uncommon, occur at roughly 0.1% of injections in US surveillance, with rare fatalities historically. Sublingual immunotherapy’s reactions are mostly local (mouth itching, mild swelling); anaphylaxis has been reported but is rare, and in Curex’s 2,897-patient peer-reviewed study adverse events were infrequent and there was no anaphylaxis. Anyone with poorly controlled asthma or a history of anaphylaxis should be evaluated in person before either route.

In-clinic allergen immunotherapy — shots or drops given at a clinic — typically costs $3,000 to $5,000 a year when you include testing, visits and the extract, and in-clinic food allergy programs can exceed $10,000 a year. With good insurance the out-of-pocket for shots may be a copay per visit, often $10–$40, times 25–50 visits in the first year. Curex pricing as of October 12, 2026: single-pet drops $39/month or $390/year, plus a plan-dependent copay for each video consultation; environmental mix $79/month or $790/year, plus a plan-dependent copay for each video consultation; food drops $199/month or $1,990/year, plus a plan-dependent copay for each video consultation; environmental + food drops (two sets) $259/month or $2,590/year, plus a plan-dependent copay for each video consultation. Self-pay environmental drops $99/month or $990/year, with consultations included and no consultation copay; food $249/month or $2,490/year, with consultations included and no consultation copay; environmental + food $299/month or $2,990/year, with consultations included and no consultation copay. Environmental allergy shots: $129/month or $1,290/year, plus a plan-dependent copay for each video consultation; self-pay $149/month or $1,490/year, with consultations included and no consultation copay. Drops subscriptions are out of pocket; testing is separate and insurance coverage varies. See /learn/curex-pricing for current rates and testing restrictions. Compare your program-specific all-in quote with those clinic costs.

Mostly the schedule. Build-up typically means one or two clinic visits a week for three to six months, each with a 30-minute wait afterward, then monthly visits for years. At-home drops remove the appointments; in Curex’s 2,897-patient peer-reviewed study, adherence was above 90%.

Personalized allergy drops are compounded for each individual patient. Such formulations are not reviewed by the FDA. However, they remain common practice for allergists and ENT allergists because they provide a convenient alternative to allergy shots. Allergy drops are the standard of care in many EU countries. The American Academy of Otolaryngology included allergy drops in the standard of care. The FDA has approved four sublingual tablets for single allergens; allergy drops are compounded, target multiple allergies at once, and remain off-label.

When you can keep a clinic schedule for years; when you have insurance that covers immunotherapy with a low copay and a clinic nearby; when you have venom allergy (drops are not used for it); when your allergist wants the closer supervision that in-clinic dosing gives, for example with asthma; and when you prefer not to manage a daily medication at home. Curex offers allergy shots for environmental allergies as well as drops.

When the shot schedule is the thing that would make you quit — shift work, travel, a rural address, no childcare, needle aversion — or when you are uninsured or on a high-deductible plan and the in-clinic price is out of reach. The route you finish is the one that works. Drops are also the only immunotherapy currently available for food allergy at home.
