How many doses does a pack of tick oral allergen last? - in detail
The duration of a single container of tick oral allergen depends on the product’s concentration, the prescribed dose per administration, and the treatment protocol. Most commercially available preparations contain 100 µg of active ingredient per sachet, with a recommended daily dose of 5 µg for the maintenance phase. Under these conditions, one pack of 30 sachets provides 30 × 5 µg = 150 µg of allergen, sufficient for 30 days of therapy.
If the initial escalation phase requires higher doses—typically 10 µg per day—the same pack yields 15 days of treatment. Some protocols employ a bi‑daily schedule during the build‑up period; in that case, the number of days is halved relative to the daily schedule.
Factors influencing the total number of administrations include:
- Patient weight and age, which may modify the dose.
- Clinical response, prompting dose adjustments upward or downward.
- Manufacturer’s specific formulation; certain brands provide 50 µg per sachet, doubling the daily dose capacity.
- Storage conditions; exposure to moisture or temperature extremes can degrade potency, effectively reducing usable doses.
To calculate the exact number of doses for a given pack, apply the formula:
Number of doses = (Total allergen content in µg) ÷ (Prescribed dose per administration in µg)
For example, a pack containing 3 g of powder with a potency of 200 µg g⁻¹ delivers 600 µg total. At a maintenance dose of 5 µg, the pack supports 120 days of therapy.
Clinicians should verify the label‑specified potency, confirm the patient’s dosing schedule, and adjust calculations accordingly to ensure accurate treatment planning.
