Wegovy Pill and Foundayo Side Effects: What to Log

Switched to a GLP-1 pill and now your stomach turns every morning? The US labels for Wegovy tablets (semaglutide) and Foundayo (orforglipron) both put nausea, diarrhea, vomiting and constipation among the most common side effects. Some of these symptoms need a call right away. The rest are worth writing down to go over with your prescriber.

The details come from the US FDA prescribing information on DailyMed, so ask your prescriber or pharmacist how they apply where you live. Semaglutide is also sold as the weekly Wegovy injection; this article covers only the daily tablets.

The two pills side by side

	Wegovy tablet	Foundayo
When	Morning, empty stomach	Once a day, with or without food
Taken with	Up to 4 ounces (about 120 mL) of plain water, no other drink	No rule on the label
Afterward	Wait at least 30 minutes before food, drinks or other oral medicines	No rule on the label
Missed dose	Skip it and take the next one the following day	Take it as soon as possible, never two in one day

If you miss Foundayo for 7 or more days in a row, its Medication Guide says to call your healthcare provider about how to restart. Both pills are swallowed whole, and both start at a low dose that goes up in steps, which the labels say is meant to reduce the risk of stomach side effects.

The same nausea reads differently on each pill

On Wegovy you wait at least 30 minutes after the tablet before eating or drinking anything else, so the pill and breakfast can end up close together. If you feel queasy later in the morning, log the pill time and your first food or drink as separate entries so your prescriber can see both.

If the time you take Foundayo changes from day to day, note the actual hour each day.

Here is a made-up example of the format:

• March 4, 07:00 Wegovy tablet / 07:40 breakfast (toast) / 09:10 moderate nausea, about 30 minutes
• March 5, 07:05 Wegovy tablet / 07:45 breakfast (porridge) / no nausea

Timing alone can’t show what caused a symptom, but it gives your prescriber the sequence of events.

While the dose is being stepped up

In the Foundayo trials, nausea, vomiting and diarrhea were more common during the dose escalation period and decreased over time.

On your daily symptom log, mark your first tablet, each increase and any long gap, so you can compare how you felt before and after each step.

For constipation, see the GLP-1 constipation guide.

Days when diarrhea or vomiting keeps going

Both Medication Guides warn that diarrhea, nausea and vomiting can cause a loss of fluids (dehydration) that may lead to kidney problems. Drinking fluids helps reduce the chance of dehydration, and symptoms that don’t go away should be reported to your healthcare provider right away. Drinking or logging is no reason to delay that call.

The NHS lists thirst, dark yellow and strong-smelling pee, peeing less often, dizziness and a dry mouth as signs of dehydration. If you feel sick, it suggests starting with small sips and gradually drinking more, and drinking enough during the day that your pee is pale.

On a day like this, log how many times you had diarrhea or vomited, how much you drank, and your urine color. For example, write “Five loose stools by mid-afternoon, three glasses of water.” It records the counts but can’t confirm you drank enough.

When to call instead of logging

The Medication Guides say to stop taking the medicine and call your healthcare provider right away for severe stomach pain that will not go away, with or without nausea or vomiting. The pain is sometimes felt through to your back. Upper stomach pain, fever, yellow skin or eyes, or clay-colored stools can mean gallbladder problems; call your healthcare provider right away. Both guides also say to stop the medicine and get medical help right away for signs of a serious allergic reaction, such as swelling of the face, lips, tongue or throat, or trouble breathing or swallowing. The NHS advises urgent help for dizziness on standing that does not go away, or for dark yellow pee or peeing less than normal.

This is not every warning on the labels, so follow your Medication Guide’s stop and emergency instructions. Other dose changes and symptom treatment are your prescriber’s call. Bring one page with your start date, dose increases, missed days, daily stomach symptoms, bowel movements with Bristol stool type, vomiting, fluids and urine color. This article is general information, not medical advice.

How bellySignal helps

bellySignal is a self-recording diary, not a medical device. It does not diagnose or record dose amounts, so dose increases go in your notes.

• Log each bowel movement with Bristol stool type 1 to 7. Trends show how often you went this week and your stool form.
• Rate urine color on a 1 to 8 hydration scale, and log water in cups or mL.
• Add your GLP-1 pill to the Meds & supplements list and log each time you take it, with optional reminders that repeat daily at the times you choose.
• Add food, and notes such as nausea, a dose increase or a missed day.
• Export a PDF summary of the last 90 days to show your prescriber.

It is free on iPhone and Android. Your diary is stored on your device, and you can start without an account. Some health values, such as stool type, symptoms and manually entered weight, are also sent to PostHog analytics, which is on by default. The analytics switch in settings controls PostHog only. Firebase Analytics receives usage events without those health values. Privacy policy.
