Pharmacist tips for Wegovy (semaglutide)
- Wegovy (semaglutide) works best when you take it with a lower-calorie diet and regular exercise. Talk to your care team about how to plan balanced meals. They can also help come up with ideas for exercise that works for you.
- You'll start Wegovy (semaglutide) at a low dose for the first month. Then, your dose will go up each month until you get to a maintenance dose. This takes 4 or 5 months. Slowly raising the dose helps lower your risk of side effects like for nausea, diarrhea, and stomach pain.
- It's common to have stomach upset as a side effect when starting Wegovy (semaglutide). But it usually gets better over time. Eat smaller meals and avoid high-fat, fried, or spicy foods to calm your stomach. Also drink plenty of fluids to help with vomiting and diarrhea. Tell your care team if these side effects get worse or don't go away. Your prescriber might lower your dose or stop the medication.
- Talk to your care team about how much alcohol, if any, is okay to drink while taking Wegovy (semaglutide). Alcohol can make side effects like nausea and bloating worse. It also adds extra calories, which can slow down weight loss. Some people might also feel less interested in drinking while taking this medication.
- You can't use Wegovy (semaglutide) pens and tablets at the same time. But you can switch from one to the other if needed. For example, if the recommended maintenance dose of the tablets hurts your stomach too much, your prescriber can switch you to the weekly injections. Follow your prescriber's directions to switch from one to the other.
How to use the Wegovy (semaglutide) pen:
- Your care team will show you how to use and how to inject Wegovy (semaglutide). They can make sure you can do it on your own. Read the instructions on how to inject the medication. Ask your prescriber or pharmacist if you have questions.
- Inject Wegovy (semaglutide) once a week, with or without food. Choose the same day and time each week that works best for you. You can change the day of the week you inject it as long as your last dose was at least 2 days ago.
- Wegovy (semaglutide) comes in 5 different strengths. Each strength has its own color-coded pen. Make sure you have the right pen for your dose.
- Be sure to inject Wegovy (semaglutide) when you're ready. Once you press the pen to your skin, the injection will start. You can't stop the injection and restart it later.
- Where to inject Wegovy (semaglutide): Inject the medication into the front of your thigh or stomach (at least 2 inches away from your belly button). You can also inject it into the outer part of your upper arm. Choose a different spot each time. Also don't inject into areas that are tender, bruised, red, hard, scarred, or have stretch marks. This helps avoid skin irritation.
- How to inject Wegovy (semaglutide): Pull off the pen cap. Then, press the pen firmly against your skin. You'll see a yellow bar start to move and hear two clicks. The first tells you when the injection starts. The second tells you that the medication is still getting injected. Keep holding the pen against your skin until the yellow bar stops moving. That means your injection is done. The injection takes about 10 seconds.

Common questions about Wegovy (semaglutide)
Risks and warnings for Wegovy (semaglutide)
Wegovy (semaglutide) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Possible risk for thyroid cancer
In animal studies with rats, Wegovy (semaglutide) was linked to a higher risk of thyroid cancer. It was more likely to happen when rats got higher doses or were given the medication for a long time. It's not known if Wegovy (semaglutide) can cause thyroid cancer in people.
Because of this potential risk, people with a personal or family history of medullary thyroid cancer (MTC) shouldn't use Wegovy (semaglutide). People with multiple endocrine neoplasia syndrome type 2 (MEN 2) also shouldn't use this medication.
Talk to your prescriber if you're worried about the risk of thyroid cancer with Wegovy (semaglutide). Call your care team right away if you notice a lump in your neck. Also tell them if you have trouble swallowing, shortness of breath, or a hoarse voice that doesn't go away. These could be signs of thyroid cancer.
Inflammation of the pancreas (pancreatitis)
Some people taking Wegovy (semaglutide) have had swelling or inflammation in the pancreas. This is called pancreatitis. It can sometimes cause serious damage to the pancreas or bleeding.
Stop using Wegovy (semaglutide) and call your care team if you have symptoms of pancreatitis. This includes vomiting or severe stomach pain that travels to your back and doesn't go away.
Gallbladder problems
- Risk factors: Children | Lose a lot of weight | Lose weight very fast
Although it's rare, some people who take Wegovy (semaglutide) can have gallbladder problems. This can include an inflamed gallbladder or gallstones.
In studies, gallbladder problems happened more often in children than in adults who took Wegovy (semaglutide). Losing a lot of weight or losing weight too fast might also raise your risk of these problems.
Tell your care team if you notice symptoms of gallbladder problems. Look out for yellow skin or eyes, fever, chills, or severe pain in your upper right stomach.
Low blood sugar
- Risk factors: Type 2 diabetes | Taking insulin or certain other diabetes medications that can lower blood sugar
Wegovy (semaglutide) can lower your blood sugar. If you take it with other diabetes medications like insulin or glipizide, your blood sugar could drop too low. This can be dangerous.
Your care team might ask you to check your blood sugar while taking Wegovy (semaglutide), especially if you have Type 2 diabetes. Tell your prescriber if you're taking any diabetes medications. Your care team might need to adjust your diabetes treatment to keep you safe.
You and your loved ones should know how to spot low blood sugar and how to treat it. Signs can include feeling very hungry, shaky, weak, or confused. You might also sweat at lot or have a racing heart or changes in vision. If you still have low blood sugar after trying to treat it, call 911 right away.
Kidney damage
- Risk factors: History of kidney damage | Long-term kidney failure | Dehydration
Some people taking Wegovy (semaglutide) have had kidney damage. Sometimes, this led them to need dialysis. People who already have kidney damage are at higher risk. But it can also happen to people without any known kidney problems.
Tell your prescriber if you have side effects like nausea, vomiting, or diarrhea while taking Wegovy (semaglutide). These can raise your risk of dehydration, which can sometimes lead to kidney damage. If the side effects are severe, you might need blood tests to check for kidney damage.
Allergic reactions
It's possible to have a serious allergic reaction to Wegovy (semaglutide). Tell your prescriber if you've had a reaction to other GLP-1 agonists. Don't use Wegovy (semaglutide) if you've had an allergic reaction to it or to other semaglutide medications (Ozempic, Rybelsus).
Call 911 right away if you have an allergic reaction. Watch for swelling in your face or throat, trouble breathing, hives, or other symptoms of anaphylaxis.
Eye problems in people with Type 2 diabetes (diabetic retinopathy)
- Risk factors: History of eye problems caused by high blood sugar | Type 2 diabetes | High risk of heart disease | Rapid improvement in blood sugar
In studies, some adults with Type 2 diabetes who took Wegovy (semaglutide) had eye problems. These included cataracts, glaucoma, and damage to the retina.
The risk is higher if you already have eye problems from high blood sugar (called diabetic retinopathy). These problems might get worse for a short time if your blood sugar improves too quickly.
Talk to your prescriber or eye specialist if your eye problems get worse while taking Wegovy (semaglutide). Also tell them if you notice any changes in your vision.
Faster heart rate
Your resting heart rate might go up while taking Wegovy (semaglutide). In studies, people taking the medication had a heart rate that was on average 1 to 4 beats per minute (bpm) higher than those taking placebo. Some even had an increase of 10 bpm to 20 bpm or more.
Your primary care provider will check your heart rate at your follow-up visits. Tell your healthcare team if you feel your heart racing while you're resting. If your heart rate stays too high, you might need to stop taking Wegovy (semaglutide).
Possible risk of self-harm
- Risk factors: History of suicidal attempts | Suicidal thoughts
In studies, some people had suicidal thoughts or behaviors while taking other weight loss medications. Because of this, you shouldn't take Wegovy (semaglutide) if you've had thoughts of self-harm before.
Call your primary care provider if you or a loved one notices signs of depression. Also let them know about any unusual changes in mood or behavior. Stop taking Wegovy (semaglutide) and call 911 right away if you think about hurting yourself. Talk to your primary care provider if you're worried about this risk.
Lung problems during general anesthesia or deep sedation
While under general anesthesia or deep sleep, some people taking GLP-1 agonists like Wegovy (semaglutide) had a serious lung problem. This happened when food or liquid got into the lungs.
Although rare, this lung problem can happen because Wegovy (semaglutide) slows down your stomach. So even if you followed instructions not to eat or drink before your procedure, food might still be in your stomach and could get into the lungs.
Before any surgery or medical procedure, tell the care team that you're taking Wegovy (semaglutide). Your care team can watch for this lung problem and help keep you safe during the procedure.
