How Often Do You Take Allergy Shots vs. Other Allergy Treatments?
Allergy shots are the only allergy treatment where frequency decreases over time and eventually stops: weekly during build-up, monthly during maintenance, then nothing after 3-5 years. With an at-home program such as Curex, eligible patients self-administer those same shots at home rather than at a clinic. Daily antihistamines and nasal steroids require the same daily dose indefinitely with no end date. Sublingual drops require daily dosing for 3-5 years with the same disease-modifying endpoint as shots.

You take allergy shots 1-2 times per week at first, then once a month during maintenance — and after 3-5 years you stop entirely. Every other allergy medication requires daily dosing indefinitely with no stopping point.
Allergy Shots: The Only Treatment That Gets Less Frequent Over Time
The word 'take' reveals an important mindset: this reader thinks of allergy shots as a medication routine — something you take regularly, like a pill. That framing makes the comparison with daily allergy medications natural and revealing.
Allergy shots are unique among allergy treatments because their dosing frequency decreases over the treatment course and eventually reaches zero. Week one: 1-2 injections per week. Month six onward: one injection per month. Year five: you stop. The immune tolerance built over 3-5 years persists for 3-12 years post-treatment per Durham et al. (NEJM 1999), meaning you stop taking the treatment and still get the benefit.
Daily antihistamines (cetirizine, loratadine) follow a completely different pattern: one pill every single day, every year, indefinitely. Stop the pill, symptoms return within 24 hours — because antihistamines block histamine receptors temporarily rather than retraining the immune system. Nasal corticosteroids follow the same pattern: daily indefinitely, symptoms return on discontinuation.
What has changed is where you 'take' the shot. With an at-home program such as Curex, eligible patients self-administer the same subcutaneous immunotherapy at home for $129/month all-inclusive — the first dose and every dose change supervised live over Zoom by a board-certified allergist, with a prescribed epinephrine auto-injector confirmed on hand — keeping the decreasing-then-stopping schedule without clinic trips. Sublingual immunotherapy drops also share the disease-modifying endpoint — 3-5 years of treatment for lasting benefit — but require daily doses; the disease modification per Cochrane reviews is comparable for many allergens.
Understanding which allergens are driving your symptoms is the first step before choosing any treatment. Services like Curex offer at-home allergy test kits covering 40+ allergens, with results in about a week, so you can start that first conversation with your allergist with a clear picture.
Allergy shots are the only allergy treatment with a decreasing frequency trajectory that eventually stops. After 3-5 years of shots, you stop — and benefits last 3-12 more years. Daily medications require daily dosing forever.

This comparison frames each treatment by how often patients 'take' it, what each dose involves, how long the regimen continues, and whether stopping leaves any lasting benefit. Data on efficacy comes from published clinical trials and Cochrane systematic reviews.

How often do you take allergy shots compared to daily allergy pills?
You take allergy shots 1-2 times per week during the 3-6 month build-up phase, then once a month during the 3-5 year maintenance phase, after which you stop entirely. Daily allergy pills such as cetirizine or loratadine are taken once per day, every day, for as long as you want symptom control — there is no stopping point. Over a 5-year period, allergy shots involve approximately 168-300 treatment events compared to 1,825 daily pills. The critical difference is that after completing a full course of allergy shots, the immune system has been durably retrained — benefits from Durham et al. (NEJM 1999) show lasting relief for 3-12 years post-treatment, even without any ongoing medication.
Is there any allergy medication that decreases in frequency over time?
Allergy shots and sublingual immunotherapy drops are the only allergy treatments with a decreasing frequency trajectory and a defined endpoint. With shots, frequency decreases from weekly to monthly over the first year, and then the treatment ends after 3-5 years total. With drops, daily dosing continues for 3-5 years and then stops. Every other mainstream allergy treatment — antihistamines, nasal corticosteroids, leukotriene modifiers like montelukast — requires the same daily dosing on day one as on year ten, with no reduction and no endpoint. This is a fundamental distinction: immunotherapy retrains the immune system, while symptom-suppressing medications only work while you are taking them.
Can allergy shots reduce the need to take daily medications?
Yes — one of the documented benefits of allergy shots is a significant reduction in the need for rescue medications. Calderon et al. (Cochrane 2007) found that SCIT reduced medication use by 36% compared to placebo in patients with allergic rhinitis. Petersen et al. (JACI 2004) reported that SCIT patients show higher quality of life at year three compared to medication-only patients, partly because many had reduced or eliminated their daily antihistamine and nasal steroid use. This medication reduction typically becomes noticeable during the first 6-12 months of maintenance. It is one of the most practically significant benefits of immunotherapy for patients managing multi-drug daily regimens.
What happens when you stop taking allergy shots after 3-5 years?
Stopping allergy shots after completing a full 3-5 year course does not cause an abrupt return of symptoms. The disease modification built over the treatment course — regulatory T-cell expansion and suppression of IgE-mediated responses — persists for years after the last injection. Durham et al. (NEJM 1999) showed that patients completing 3 years of grass pollen SCIT maintained significantly lower symptom scores for at least 3 years post-discontinuation compared to placebo. Some patients maintain benefit for 10-12 years. Relapse rates after a complete course are approximately 10-25% within 5 years, compared to near-100% symptom return within 24-72 hours of stopping daily antihistamines.
How does the experience of 'taking' allergy shots compare to taking a daily pill?
The experience of taking allergy shots and taking a daily allergy pill are fundamentally different in time and effort per dose. A daily antihistamine takes 10 seconds and requires no clinic visit. An allergy shot visit takes approximately 1 hour: travel, check-in, the injection itself (seconds), and the mandatory 30-minute post-injection observation period. However, allergy shots are taken far less frequently — 52-60 times in year one vs. 365 pills — and have a defined endpoint. The per-event burden is much higher for shots, while the per-dose effort for pills is minimal. Quality of life research by Petersen et al. (JACI 2004) found that despite higher early burden, SCIT patients report better QoL at year 3 than medication-only patients.
How does SCIT frequency compare to montelukast?
Montelukast (Singulair) is taken once daily, every day, indefinitely — just like antihistamines. Wilson et al. (Arch Int Med 2004) found a number-needed-to-treat of approximately 8 for montelukast to produce meaningful symptom improvement, suggesting modest efficacy for allergic rhinitis. Montelukast provides no disease modification: stopping it causes symptoms to return. Over a 5-year period, a patient takes approximately 1,825 montelukast doses with no immune system change. By contrast, 3-5 years of allergy shots involve 168-380 treatment events but leave a durably retrained immune system that may maintain benefit for 3-12 years after the last injection. The FDA added a black box warning to montelukast in 2020 due to neuropsychiatric side effects, which has shifted prescribing patterns.
Are allergy shots worth taking compared to daily medications?
Whether allergy shots are worth the treatment burden compared to daily medications depends heavily on individual circumstances. The evidence supports immunotherapy's advantage for patients with moderate-to-severe allergic rhinitis who want long-term disease modification rather than lifelong symptom suppression. Cochrane reviews show SCIT reduces symptom scores by 33% and medication use by 36% compared to placebo. Quality of life studies by Petersen et al. (JACI 2004) show SCIT patients outperform medication-only patients on standardized QoL scales at year three. Cost analysis by Hankin et al. (Ann Allergy 2013) finds SCIT becomes cost-neutral vs. ongoing medication at approximately 3 years and cost-saving by 5+ years. For patients who can maintain the schedule, the long-term return typically justifies the early investment.
