The label’s own words
Every alert quotes the sentence from the FDA-approved labeling, names the section it came from, and carries the date that labeling took effect and the label’s identifier. Your pharmacist can read exactly what you read.
Interaction alerts that quote the label, not an opinion
Add what you take and Loopa checks it against FDA-approved product labeling, against your other medications, your supplements, and the food and drink you log. When a label says something about the combination, you see the label’s own sentence.
It is free. Information about what you take belongs to you, not behind a subscription.
What you actually see
Timing, against what you logged
Where a label describes keeping a gap between two things, Loopa compares it with the times you actually recorded. “you logged these 30 minutes apart on Tuesday, where the label describes four hours.”
Food and drink, not just pills
Grapefruit, alcohol, caffeine, dairy and calcium, iron, vitamin K, tyramine-rich foods. If the FDA-approved label names it and you logged it, the check sees it. Every one of those comes from the manufacturer’s own labeling, read through the openFDA drug label API, not from anybody’s opinion.
One tap to log a dose
And Loopa tells you it landed. Your adherence feeds the report you can hand a clinician.
What it does not do
It never says “safe”
It can only tell you what a label states. A label that states nothing is not an all-clear, and Loopa will not pretend otherwise. When nothing turns up it tells you exactly what it checked and against what.
It never changes your dose
No dosing, no “stop taking this”, no diagnosis. Every alert points you to a pharmacist or prescriber, because that is who decides.
Severity means where, not how bad
A boxed warning outranks a note under precautions because of where the label puts it, not because Loopa graded it. That ordering is set by the FDA prescribing-information rules that govern how prescribing information is written. The app says so on every alert.
Nothing about you leaves
Loopa keeps its own copy of the public labeling and runs the check on our servers. Nothing about you is sent to the FDA or anyone else to perform it.
On GLP-1, testosterone or hormone therapy?
GLP-1Protein first, calories as a floor, a dose log with a body map, and the Off-Ramp.
Testosterone therapyResistance-forward training, several compounds on their own schedules, and labs with no reference ranges.
Menopause & HRTBone-first training, a sleep card, and a symptom journal that leads with hot flashes and night sweats.
Common questions
Where does the information come from?
FDA-approved product labeling, obtained through openFDA and refreshed weekly. Every alert carries the version it came from, and so does the report you can share with a clinician.
What combinations are covered?
Medication with medication, with a supplement, with food, with alcohol and with caffeine, to the extent the labels state them. Supplement-to-supplement combinations are not covered, because FDA drug labels do not state them, and Loopa says so rather than letting you assume the check was exhaustive.
Is this medical advice?
No. It shows you what approved labeling states so you can raise it with a pharmacist or prescriber. It never tells you a dose, never tells you to stop taking anything, and never diagnoses.
My pharmacist flagged something Loopa did not.
Expected, and your pharmacist is the authority. Loopa reports what product labeling states; a pharmacist draws on clinical references well beyond labeling and on your own history. Also check that every item on your list was matched when you added it, an item typed without picking a suggestion cannot be checked, and its row says so.
Do I have to pay for it?
No. Adding medications, logging doses, the interaction check and the alert list are all free. The report you can hand to a clinician is Premium.
