Why adherence tracking matters

Adherence is one of the most underestimated factors in treatment outcomes. Studies consistently show that 50% or more of patients with chronic conditions don't take their medications as prescribed, leading to preventable complications, hospitalizations, and higher healthcare costs.

What counts as good adherence?

The standard clinical threshold is 80% for most chronic medications. That means taking at least 4 out of every 5 scheduled doses. For high-stakes drugs like HIV antiretrovirals, seizure medications, or transplant immunosuppressants, 95% or above is required to maintain therapeutic effect.

Common causes of missed doses

Forgetting is the most common reason, especially for twice-daily or more frequent regimens. A visual medication schedule can help you build a consistent routine and see at a glance when each dose is due throughout the day.

Running out of medication is another frequent cause. Pairing this tracker with our refill reminder tool lets you monitor your remaining supply and set alerts before you hit zero.

How to interpret your adherence rate

  • 95% or above: Excellent. You're meeting the threshold for even the most demanding medications.
  • 80 to 94%: Good for most chronic conditions. Worth reviewing which doses you're missing and why.
  • Below 80%: Talk to your pharmacist or prescriber. They can help simplify your regimen or adjust dosing times.

Frequently asked questions

Medication adherence means taking your medications at the correct dose, at the right times, and for the full duration prescribed. Good adherence — generally 80% or higher — is linked to better treatment outcomes and fewer hospitalizations.
Your adherence rate is the number of doses you marked as taken, divided by the total number of scheduled doses in the selected period, shown as a percentage. Missed and skipped doses both count against the rate.
No. All data is saved locally in your browser using localStorage. Nothing is sent to any server. Clearing your browser data or switching browsers will erase your history.
Most clinical guidelines define acceptable adherence as 80% or above for chronic medications like antihypertensives, statins, and diabetes drugs. For HIV antiretrovirals and transplant immunosuppressants, 95% or higher is the recommended threshold. Talk to your pharmacist if you're consistently below target.
Taken means you took the dose as scheduled. Missed means you forgot or were unable to take it. Skipped means you intentionally did not take it, for example on your doctor's advice. Both missed and skipped count against your adherence rate.
