Medication Reminders
Injection Reminder App: For Weekly, Biweekly, and Monthly Shots
Injectable medications rarely run on a daily cycle. GLP-1 medications like Ozempic and Mounjaro are typically weekly. Testosterone and other hormone therapies are commonly weekly or biweekly. B12 is often monthly. Biologics like Humira or Enbrel vary by prescription — weekly, every other week, or longer. Each of these needs a reminder built around its actual interval, not a generic daily pill reminder repurposed for something it wasn't designed for.
This article covers reminder app features only. Always follow your doctor's or pharmacist's instructions for dosing schedules and never adjust injection timing without medical guidance.
Why "once a week" reminders drift
The common approach — a phone alarm set for "every Monday" — works until the injection happens on a Tuesday one week, for any of the ordinary reasons a schedule shifts: travel, a forgotten dose, a pharmacy delay. The alarm stays locked to Monday regardless, so from that point on it's reminding you on the wrong day relative to when you actually last injected.
An interval-based reminder solves this by counting from the last dose, not from a fixed weekday. Set it to repeat every 7 days, and if you inject on Tuesday instead of Monday, the next reminder automatically shifts to the following Tuesday — matching your actual schedule instead of an idealized one.
Common injection schedules
💉
Weekly GLP-1 medications
Set interval: 7 days
Ozempic, Mounjaro, Wegovy, and similar — same day each week, adjusted if timing shifts
💉
Hormone therapy (HRT / testosterone)
Set interval: 7 or 14 days
Weekly or biweekly protocols, often with a site-rotation habit alongside the reminder
💉
Monthly B12 or Depo-Provera
Set interval: 28–30 days
Not the same as "the 1st of every month" — an interval-based reminder handles both
💉
Biologics (Humira, Enbrel, etc.)
Set interval: varies by prescription
Weekly, every-other-week, or monthly depending on the specific medication and dosing plan
Setting up an injection reminder
1
Download RippleFree on the App Store and Google Play. No account required.
2
Tap +Opens the Create Alarm screen.
3
Set the time of your next injectionThis becomes the anchor point the whole cycle counts from.
4
Set the interval7 days for weekly, 14 for biweekly, 28–30 for monthly — confirm the exact number with your prescription.
5
Name it clearlyInclude the medication name, especially if you're managing more than one injectable.
Dismiss the alarm once the injection is done, and Ripple schedules the next one from that exact moment — so if this week's dose happens a day later than planned, next week's reminder moves with it instead of staying locked to the original day.
Why "day of the week" reminders aren't quite right
A reminder that always fires on Monday assumes every injection also happens on Monday, every time, without exception. In practice, appointments move, supplies run short, and travel gets in the way — any of which shifts the actual injection day without shifting the reminder that's meant to track it. An interval reminder that resets from the last dismissal stays accurate through those normal, ordinary shifts, rather than requiring you to manually recalculate the schedule each time something changes.
Frequently asked questions
What's the difference between a weekly reminder and a 7-day interval reminder?
A weekly reminder tied to a specific day (e.g., "every Monday") stays fixed to that day regardless of when you actually last injected. A 7-day interval reminder counts forward from your last dismissal, so if you inject a day late one week, the following reminder automatically adjusts to keep the same 7-day spacing from your actual dose — not from the calendar.
How do I handle a biweekly (every 14 days) injection schedule?
Set the interval to 14 days rather than trying to track "every other Monday" on a weekly reminder, which is easy to lose track of. A dedicated 14-day interval keeps the spacing exact regardless of which day of the week it lands on.
Can I track injection site rotation alongside the reminder?
Some interval alarm apps, including Ripple, let you use the alarm's history or notes to log details like injection site alongside the date — useful for medications where site rotation is recommended to reduce irritation. Check your specific prescription guidance for site rotation practices.
Is a reminder app enough to manage an injection schedule safely?
A reminder app handles timing, not clinical judgment — it can't verify correct technique, catch a missed refrigeration requirement, or flag a drug interaction. Use it alongside your prescriber's and pharmacist's instructions, and keep a physical log or count of remaining doses as a backup check.
