# Do GLP-1s affect the absorption of other medications

> Learn how GLP-1 medications can affect absorption of oral drugs by slowing gastric emptying and when dose adjustments may be needed for safe use.

## Do GLP-1s affect the absorption of other medications?

Yes, they *can*, mainly because GLP-1 medications **slow gastric emptying**, which means pills you take by mouth may move through your stomach more slowly. In Dr. Alexandra Sowa’s words, with delayed gastric emptying, “if you’re taking anything orally sometimes you might need to adjust medications.”

What that looks like in real life is usually less about a dangerous interaction and more about timing and dosing, especially if you’re on medications where small changes matter. Dr. Sowa calls out a few common examples where dose adjustments sometimes come up as weight changes, like blood pressure meds and thyroid medication, and she notes it *might* be similar for hormones you’re taking, depending on the person.

At Alloy, this is exactly why we monitor you, especially early on, because side effects like nausea or vomiting can also make it harder to keep oral meds down consistently. For the most relevant part, you can watch Dr. Sowa talk about this here: [“Adjusting medications with weight changes”](https://www.youtube.com/watch?v=PQ60VjfnliA&t=3076s)
