How to Support Someone Taking GLP-1

Supporting someone on a GLP-1 medication starts with following their lead, not tracking their progress. The most useful things you can do are learn what the medication actually involves, know which symptoms call for prompt medical attention, and help them carry the right questions into their appointments — without turning mealtimes or the bathroom scale into something to monitor.

Start With Permission, Not Monitoring

Before anything else, ask the person directly what kind of support they actually want. Some people want a check-in partner for injection day; others would rather their treatment stay private, even from close family. Both are reasonable, and the second one doesn't mean something is being hidden from you.

• Ask how much they want to share, and with whom, rather than assuming.
• Avoid commenting on their portions, their weight, or how their body looks, even as encouragement — it can read as surveillance.
• Let them bring up side effects or progress first, instead of asking how much weight they've lost or whether they took their dose.
• If they ask you to help track doses or appointments, treat that as their choice to revisit, not a standing assignment.

Learn What They're Actually Taking

GLP-1 is a drug class, not one product, and the schedule differs by medication. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), liraglutide (Saxenda) is given daily by injection, while semaglutide (Wegovy, Ozempic) and tirzepatide (Zepbound, Mounjaro) are given weekly.

For semaglutide specifically, MedlinePlus (a National Library of Medicine patient-information service) notes that doctors typically start patients on a low dose and increase it after four weeks, with a possible second increase four weeks after that, based on how the person responds. Liraglutide and tirzepatide follow their own titration schedules — if the person you're supporting is on one of those, their own medication guide (provided with the prescription) will have the specific numbers, since they differ from semaglutide's.

Medication and Appointment Facts Worth Having On Hand

If they want your help staying organized, these are the details that matter in a medical conversation — not a food log:

• The exact drug and brand name, current dose, and injection day or schedule.
• The prescribing clinician's name and contact information, and any lab tests they're due for — MedlinePlus notes that doctors typically order periodic tests to check how the body is responding.
• Other medications, supplements, or herbal products they're taking, since both MedlinePlus and NIDDK note these can interact or require dose adjustments.
• Any personal or family history of medullary thyroid cancer or multiple endocrine neoplasia syndrome type 2, which NIDDK lists as a reason not to take liraglutide, semaglutide, or tirzepatide at all.
• Whether they are pregnant, breastfeeding, or planning a pregnancy. For semaglutide, MedlinePlus notes doctors advise stopping the medication two months before a planned pregnancy; NIDDK notes none of these medications are recommended during pregnancy or breastfeeding.

Warning Signs That Need Prompt Medical Care

MedlinePlus lists specific symptoms that call for contacting a doctor immediately or getting emergency care. It's worth knowing these so you can recognize them if the person you're supporting mentions how they're feeling:

• Ongoing pain starting in the upper or middle stomach that may spread to the back, with or without vomiting — a possible sign of pancreatitis.
• Pain in the upper stomach, yellowing of the skin or eyes, fever, or clay-colored stools — possible signs of gallbladder problems.
• A lump or swelling in the neck, hoarseness, difficulty swallowing, or shortness of breath — tied to the medication's warning about thyroid tumors seen in animal studies; it's not known whether this risk applies to humans.
• Rash, itching, fainting or dizziness, swelling of the eyes, face, mouth, tongue, or throat, or difficulty breathing or swallowing — signs of a serious allergic reaction.
• Decreased urination or swelling of the legs, ankles, or feet — MedlinePlus lists these alongside a caution that ongoing diarrhea, nausea, vomiting, or an inability to keep liquids down can lead to dehydration.
• Vision changes, or a rapid or pounding heartbeat.
• For anyone also managing diabetes: dizziness, sweating, shakiness, or confusion, which can signal low blood sugar.

Separately, NIDDK notes that the FDA continues to review reports of suicidal thoughts or actions in people taking certain weight-loss medications, and is still evaluating whether the medication is the cause. If the person you're supporting mentions a noticeable change in mood, or says anything that concerns you, encourage them to raise it with their prescribing clinician without delay — that's a conversation for their care team, not something to assess on your own.

What This Page Can and Can't Settle

This page can tell you what NIDDK's clinical overview and the National Library of Medicine's drug information say about these medications in general. It can't tell you whether a specific symptom the person you're supporting is having is caused by their medication, something else entirely, or nothing concerning at all — that distinction belongs to their prescribing clinician, who has their full medical history. When in doubt, the next step is a call to that clinician, not a guess based on what you've read here.

Questions to Bring to Their Care Team

• What should happen if a dose is missed? As one example, MedlinePlus notes that for semaglutide taken for weight loss, a missed dose can be given within 48 hours; after that, it's skipped and the regular schedule resumes. Other GLP-1 medications have their own rules, so it's worth confirming the exact one for their specific prescription.
• Which symptoms warrant a same-day call to the office, and which warrant an ER visit instead?
• Are there supplements, over-the-counter medicines, or other prescriptions that shouldn't be combined with this one?
• NIDDK notes that if someone hasn't lost at least 5% of their starting weight after 12 weeks on the full dose, their clinician will likely discuss next steps — it's worth knowing in advance what that conversation might look like.
• What's the plan if side effects don't improve, or get worse instead of better over time?

If They Want to Talk About Food or Weight

Let them set the terms of that conversation. Avoid offering opinions on what they're eating or how much, even supportively meant, since appetite and food intake are exactly what this medication class is designed to affect, and unsolicited comments can land as judgment. If you notice signs that something around food or eating feels distressing to them, the most helpful thing you can do is encourage them to raise it with their prescribing clinician or a mental health professional — that's a conversation for their care team, not something to manage between the two of you.

It's also worth a gentle heads-up: ads for “natural” tricks that claim to mimic these medications are common, and none of them do. Our look at the pink salt diet trick walks through why a kitchen recipe can't reproduce a prescription GLP-1 medicine, in case that kind of ad comes up.
