Medications and interaction alerts
Loopa can hold your medication list and tell you what the FDA labeling says about combining them. With each other, with your supplements, and with the food and drink you log.
You will find it under Health, then Medications. It is not behind Premium. Information about what you take belongs to you.
Adding what you take
Start typing a name and Loopa suggests matches from a reference list built from FDA product labeling. Pick the match. An item you type without picking one is kept on your list, but it cannot be checked for interactions, and its row says so rather than letting you assume it was covered.
Add the strength, how often you take it, and roughly when. Logging a dose afterwards is one tap, and Loopa tells you it landed.
Supplements live on the Supplements page and both lists are checked together.
What the check covers
Loopa reads FDA-approved product labeling and finds where a label says something about combining one of your items with another. It covers:
- medication with medication
- medication with a supplement
- medication with food
- medication with alcohol
- medication with caffeine
Supplement-with-supplement combinations are not covered. FDA drug labels do not state them, so this source cannot answer them, and Loopa says so rather than leaving you to assume the check was exhaustive.
What an alert actually shows you
The label's own sentence, word for word. Which section of the label it came from. The date that labeling took effect, and the label's identifier.
That is the point of it. Loopa is not making a claim about your medication. It is showing you what the FDA-approved labeling says, so you and your pharmacist can read the same words.
Where a label describes keeping a gap between two things, Loopa compares that against the times you actually logged and tells you what it saw: "you logged these 30 minutes apart on Tuesday, where the label describes keeping four hours between them."
What "severe" means here
It means where the label puts the information, not how dangerous something is for you.
- Severe. Stated in a boxed warning or under contraindications, the strongest things a label carries.
- Major. Stated under warnings.
- Moderate. Stated under precautions or drug interactions.
- Timing. About when to take things relative to each other.
- Informational. Mentioned in the label's patient information.
A moderate note about something you take every day may matter more to you than a severe one about a drug you took once. Your pharmacist or prescriber decides what any of it means for you.
What Loopa will never do
- It will never tell you a combination is safe. It can only tell you what a label states, and a label that states nothing is not the same as an all-clear.
- It will never tell you to start, stop or change a dose. Every alert points you to a pharmacist or prescriber.
- It will never send anything about you to the FDA or anyone else to run the check. Loopa keeps its own copy of the public labeling and does the work on our own servers.
"No interactions found"
When nothing turns up, Loopa tells you exactly what it checked and against what: "No interactions found among 6 items checked against FDA product labeling (openFDA label dataset, version 2026-08-24) on 24 August 2026."
That is not the same as "you have no interactions". It means nothing was stated in the labeling for the items Loopa could match. Keep your list current, and tell your pharmacist and prescriber everything you take, including supplements.
How current it is
The labeling data refreshes weekly. Every alert carries the version it came from, and so does the report you can share with a clinician.
