Your spray,
explained.

Your prescription is the same weekly milligram total you would have had by injection. What changes is how it is applied: an injection puts the whole week into a single dose, and the spray divides that same weekly total across five daily applications, Monday to Friday.

Because the week is split into five parts, each single application is a small number. That is expected.

It depends on your weekly dose. The large figure on the front of the bottle is your total for the whole week — what you apply each day is the smaller per-dose line underneath it. Neither tells you a spray count.

If you are not sure which row is yours, message your care team before you start. Do not guess the number of sprays.

No — and it is the question this table raises most often. A 10 mg weekly dose is two sprays a day, while 7.5 mg is three.

The reason is that bottles are filled at different concentrations. A higher-tier bottle carries more medicine in the same 0.20 mL spray, so it can reach a larger weekly total in fewer sprays. The spray count on its own is not a measure of your dose.

Always apply the number of sprays on the row that matches your prescription, not the number a friend on a different tier applies.

Each missed day is twenty percent of your weekly dose; two missed days is forty percent. That is a larger share than a missed day on a daily medication.

Do not change your dose to make it up. Tell your care team how many days you missed and follow the direction they give you.

Yes — once per bottle, when you first open it.

Priming is a one-time step for each new bottle. You do not repeat it daily.

Your dose is unaffected. This is a metered pump: it dispenses the same measured amount whether the pattern is a fine mist or a stream. Only the spray pattern has changed. Do not re-dose, and do not skip a dose, because of how it looks.

It happens when air reaches the nozzle quickly after use and a little solution dries in the tip.

If it still will not clear after both steps, message your care team rather than continuing with a bottle you are unsure about.

Yes — but it must travel in your carry-on. Never put it in checked baggage.

The reason is mechanical rather than administrative: pressure changes in the hold can damage the pump mechanism, and a damaged pump no longer delivers a measured dose.

Keep it in its original labelled bottle. For questions about travelling with a prescription — particularly internationally — message your care team before you travel.

Your bottle is filled to last four weeks on the five-day schedule.

There is a second limit that is easy to miss: discard the bottle 30 days after you first use it, even if some is left. Note the date you open it.
