Weekly medication reminder: set up a repeating one
Medication once a week or every 4 weeks: how to set a repeating reminder, log each dose with its date, and what to ask your pharmacist.
On this page
A medication you do not take every day has no fixed place in your routine, so the day slips by easily. In Sam you set a medication to repeat every few weeks or months, log each dose with its date, and see when the next one is due. This article shows how to set a repeating reminder for a weekly or every-4-weeks medication, and what to ask your pharmacist.
Why are some medicines taken weekly or every few weeks?
The rhythm is set by the manufacturer and your prescriber. Medical News Today names one reason: how long an active ingredient stays in the body. Some extended-release forms are built to make an active ingredient last longer in the body. For you this means the interval belongs to your medicine and is not yours to choose.
So this article does not say which rhythm is right, and it never suggests changing one. It helps you keep to the rhythm your prescriber and pharmacist gave you.
Who tells you which day applies?
The patient leaflet and your prescriber. According to gesund.bund.de, the leaflet states how much to take, at which times and for how long, and if something is unclear you ask a doctor or pharmacy.
An app does not change that. It reminds you of the day you give it. Whether that day is right is a question for your pharmacist or prescriber.
What can you ask your pharmacist?
These questions help, and the answers come from your pharmacist or prescriber:
- How often do I take it, and on which day or at which interval?
- Can the day be written on the pack?
- Does a fixed weekday count, or the gap since the last dose?
- Does it matter whether I take it with food?
- Whom do I ask if I am unsure?
MedlinePlus advises asking your provider or pharmacist first whether you can take a medicine with food, and talking to your provider if you have trouble remembering it. The NHS says pharmacists advise on how to use a medicine.
What applies when a day slips by depends on the medicine. The NHS Specialist Pharmacy Service, a page written for health professionals, names the patient leaflet as the first source. For anything it does not answer, ask your pharmacist or prescriber. This article gives no rule for it, and neither does Sam.
Alarm, calendar, pill organiser or app: which fits a medication you take less than daily?
All four work, and each has a limit:
- A phone alarm is quick to set but does not record when you actually took the dose.
- A calendar entry reminds you and can repeat. A monthly repeat is tied to the date, as the next section explains.
- A pill organiser sorts the days you take something. It fits a medication that comes round every few weeks poorly.
- An app reminds you and keeps a record of each dose. That helps when you want to say later when you last had it.
MedlinePlus lists alarms on a clock or phone and a chart to tick off as aids. Whether one of them helps you is something you find out by trying. If none fits, a pharmacist can suggest other ways. For daily routines see forgot to take your medication.
Monthly or every 4 weeks: what is the difference?
A month is 28 to 31 days. Four weeks is always 28 days. If a calendar repeats an entry "monthly", say on the 15th, the gap is sometimes 28 days and sometimes 31. A 4-week rhythm therefore slides against the date and drifts over the year.
Which gap applies to your medicine is on the pack and the prescription. If it says "monthly" and you are not sure whether that means calendar months or 4 weeks, ask.
In Sam the medication repeats from the day you logged for the last dose. With "Every 4 weeks" that is always 28 days after that entry. "Every month" counts calendar months from that entry.
How do you set a reminder every 4 weeks in Sam?
You add the medication to your personal medication list, by search or under a name you choose. Under How often choose Other, then Weeks or Months and a number from 1 to 12, for example Every 4 weeks. Under Next dose you set the day of the first dose, up to a year ahead. Under Remind me at you set the time; 9 am is pre-set.
On the due day you get a notification at that time: "Medication due". It is separate from the daily reminders and shows no dose. There is no fixed-weekday pattern. If your prescriber names a particular weekday, set that day under Next dose. If you later log a dose on a different day, Sam counts on from that day and the weekday shifts. Whether your medicine should stay on its original weekday is a question for your pharmacist or prescriber.
The reminder is a notification on your device that appears when Sam has scheduled it. For an important medication, do not rely on it alone.
How do you log the dose and keep the history?
The notification has no buttons. Tapping it opens Sam. There you tap I had it and choose the day you took the medication ("Which day did you have it?"). It can be a day in the past. Or you log it as Skipped.
The medication card then shows the next day, "Due today" or, once the day has passed, how many days overdue. Sam counts from the last logged dose. A skipped entry does not move the next day. That is arithmetic on your entries, not advice about the rhythm.
How to record a change in dose is covered in logging a dose change.
What does the doctor report show, and what does it not?
Only medications linked to a program appear in that program's doctor report. A program is its own diary with a doctor report and a monthly questionnaire. The report lists repeating medications under Regular treatments: the days you logged in the period you chose, the gaps between them, skipped doses and the last dose. There is no percentage.
Sam has no separate export of the medication list. What to bring to a visit is in your medication list for the doctor.
What does Apple Health offer for medication you do not take daily?
According to Apple Support, you can set schedules on specific weekdays and on cycles from iOS 18, plus reminders and a history. Sam has no weekdays or cycles. A side-by-side look is on Sam and Apple Health.
An import from Health brings medications into Sam but not a weekly or monthly rhythm, and Health keeps reminding you about imported ones. Pick one place for the reminder, or two apps will remind you about the same medication.
Log weekly or monthly doses in Sam and keep the reminder
You see in one place when you last took it and when it is due again.
- Instead of a calendar monthly repeat: Sam counts from the last logged day, so "Every 4 weeks" is always 28 days.
- Instead of an alarm with no history: you log each dose with its day, also after the fact, and get a notification on the due day at the time you choose.
- Instead of loose notes for the appointment: if the medication belongs to a program, a diary with a doctor report, the days appear in that report.
Sam reminds and records. Your prescriber and pharmacist set the rhythm. More on the medication list in Sam.

How does Sam remind me?+
With one notification on the due day at the time you choose, separate from the daily reminders. It has no buttons. Tapping it opens Sam, where you log the dose.
