Depo shot due date

Schedules for the listed products come from each product's own labelPage updated Sources

Enter the date of your last injection and choose your product. The tool shows the routine date of the next injection that the label sets, and how many days have passed since your last injection.

Choose your country and your injection, then enter the date of your most recent shot. The tool shows the routine date of your next injection that your product's label sets, or keeps the date your clinic gave you. You can print it, or save it to your calendar as a plain "Reminder".

How the routine schedule works

Each injection has its own label, and the labels don't all set the same interval. That is why the tool asks for your country and product first.

  • Depo-Provera CI (US, injected into a muscle): the label sets the next injection 13 weeks (91 days) after the last injection. The CDC's contraception guidance for clinicians gives the same interval.
  • The US injection given under the skin (depo-subQ provera 104): the label gives a range, not a single day. It schedules the next injection 12 to 14 weeks (84 to 98 days) after the last injection, and the tool shows both ends of that range.
  • Sayana Press (UK, given under the skin): the UK product information sets injections 13 weeks apart.
  • Depo-Provera (UK, injected into a muscle): the tool gives no date. The next section explains why.

Why there is no date for UK Depo-Provera

For Depo-Provera injected into a muscle in the UK, the product information and UK guidance give different routine intervals. The UK product information (the SmPC) says repeat injections are given every 12 weeks. UK guidance for clinicians advises every 13 weeks. Because they differ, the tool does not choose between them. Use the date your clinic gave you. The tool can save that date as a reminder, exactly as given, without any calculation.

How to read the result

  • The day of your last injection is the first day of the count. Every interval on this page is a whole number of weeks, so the routine date, and both ends of the range for the injection under the skin, fall on the same day of the week as your last injection.
  • The tool also shows how many days have passed since your last injection.
  • If the routine date is before today, the tool says the date has passed and links to the help page. For the US injection given under the skin, the range counts as passed only once its last day is before today.
  • Dates are calendar days. Your time zone and the time of day don't change them.

What this tool does not do

It works out the routine next date for an injection schedule you are already on. It can't help when:

  • this is your first injection, or your first of this type;
  • you are starting again after a break, or switching from another method;
  • you recently gave birth, had a miscarriage or had an abortion;
  • you aren't sure of the date of your last injection, or which type it was;
  • something went wrong with your last injection, for example some of it leaked;
  • you take, or recently stopped taking, another medicine;
  • you think you might be pregnant;
  • your injection isn't in the list.

In these cases, follow the leaflet that came with your injection and get help from a pharmacist or clinic. If your clinic gave you a different schedule, use their date.

This tool does not assess protection from pregnancy.

A worked example

This example uses a made-up date. Say your last Depo-Provera CI injection in the US was on Tuesday, 5 January 2027. With the label's interval of 13 weeks (91 days), the next routine injection is on Tuesday, 6 April 2027.

For the US injection given under the skin, a last injection on Tuesday, 19 January 2027 gives the label's range from Tuesday, 13 April 2027 to Tuesday, 27 April 2027.
