What is Wegovy?
Wegovy is a prescription weight-loss injection for individuals who are obese or overweight and have a medical condition directly connected to their excess weight.
For best results, use Wegovy with a calorie-restricted diet and regular exercise.
Due to the presence of semaglutide in Wegovy, it should not be used with any other GLP-1 receptor agonist medications.
It is unknown whether this drug interacts negatively or positively with other weight reduction supplements (prescribed, over-the-counter, or herbal).
It is also unknown whether Wegovy is safe for persons who have had pancreatitis in the past.
Wegovy’s effectiveness and safety in children under 18 have yet to be established.
Warnings and Precautions
Further evaluation is warranted if an elevated blood calcitonin level is found or if thyroid nodules are detected via a physical examination of the neck.
Serious and potentially deadly hemorrhagic or necrotising pancreatitis has been linked to semaglutide. Clinical trials of Wegovy® showed such results. Keep an eye out for signs of acute pancreatitis (including persistent severe abdominal pain, sometimes radiating to the back, which may or may not be accompanied by vomiting). Quit Wegovy® if acute pancreatitis is suspected.
1.6% of those on Wegovy® and 0.7% of those taking a placebo had cholelithiasis or gallstones. Cholecystitis affected 0.6% of those who took Wegovy® and 0.2% of those who took a placebo. People who used Wegovy® were more likely to have acute gallbladder sickness than those who took a placebo. It was true even after considering weight loss. Clinical evaluation and gallbladder testing are necessary in cases of suspected cholelithiasis.
Wegovy® may cause low blood sugar levels. Patients on Wegovy® were more likely to have hypoglycemia (6.2% vs 2.5%). Patients with type 2 diabetes on an insulin secretagogue (such as sulfonylurea) or insulin may be at a higher risk of hypoglycemia if they also take Wegovy®. Patients should know about the dangers of hypoglycemia and what to do if they experience it. Those with type 2 diabetes should keep an eye on their sugar levels.
People who have taken semaglutide have reported experiencing acute kidney injury and increasingly severe chronic renal failure, leading to the need for hemodialysis. Acute kidney injury has occurred in some patients without preexisting renal disease. Patients who had been experiencing severe nausea, vomiting, or diarrhea and had lost a significant amount of fluids were disproportionately affected.
Patients who report severe gastrointestinal reactions to Wegovy® or renal impairment or those who experience adverse events that might lead to fluid depletion should have their renal function monitored throughout initiation or increase in dose.
Extremely sensitive reactions to Semaglutide have been reported (anaphylaxis, angioedema). If hypersensitivity responses occur while taking Wegovy®, quit the drug immediately and seek medical attention.
GLP-1 receptor agonists should be used cautiously in individuals with anaphylaxis or angioedema. Retinopathy caused by diabetes complications from diabetes: researchers found that 4.0% of those given Wegovy® experienced diabetic retinopathy, compared to 2.7% of those given a placebo. Short-term improvements in diabetic retinopathy may be achieved with aggressive glucose management. Patients with diabetic retinopathy should be monitored for any signs of worsening.
Increasing heart rate. Wegovy® participants in clinical trials reported a 1 to 4 bpm greater resting heart rate than placebo patients. Patients on Wegovy® had a higher prevalence of 10–19 bpm and 20 bpm+ baseline changes compared to placebo. Contact your doctor immediately if you have palpitations or a fast heartbeat at rest. When patients’ resting heart rates increase, they stop Wegovy® treatment.
Clinical trials of many weight-loss medications have shown increased suicidal ideation and behaviour. Take note of changes in mood that could indicate depression. Discontinue Wegovy® in those who have attempted suicide or who are currently suicidal.
Who should not use Wegovy?
You should not use Wegovy if:
- you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC), or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Wegovy pregnancy and breastfeeding warnings (more details)
- Wegovy® hasn’t been tested in insulin-treated individuals. Lessen insulin secretagogues (such as sulfonylureas) or insulin doses while starting Wegovy® to reduce hypoglycemia risk.
- Wegovy® delays stomach emptying and may affect oral drug absorption. Wegovy® may interact with oral medicines.
- Wegovy slows digestion and absorption of oral medications.
- Tell your doctor about all your medications, including insulin, dulaglutide, exenatide, liraglutide, Byetta, Trulicity, Victoza, and others.
- Other medications, vitamins, and herbal items may interact with Wegovy. Let your doctor know about all your medications.

Common questions about Wegovy
Here are some answers to questions that are often asked about Wegovy.
No, the company that makes Wegovy hasn’t shared reviews from people who’ve used it.
You can find out more about what to expect from Wegovy by going to the website. Or you can read the drug’s prescribing information.
For more information, talk with your doctor or pharmacist.
Wegovy, Ozempic, Trulicity, and Victoza are all glucagon-like peptide-1 (GLP-1) agonists,one group of drugs. But they are not the same in several ways.
The active substance semaglutide is in both Wegovy and Ozempic. The active ingredient of Trulicity is called dulaglutide, and the active drug in Victoza is liraglutide.
The FDA has approved Ozempic, Trulicity, and Victoza to treat type 2 diabetes.
This is not a good way to use Wegovy. Instead, Wegovy is approved for long-term weight control in certain adults when used with workouts and a low-calorie diet. (See “Wegovy for weight loss and weight management” above for more information.)
Talk to your doctor or pharmacist to find out how Wegovy differs from Ozempic, Trulicity, and Victoza.
The company that makes Wegovy has not shown before-and-after pictures of people who have taken the drug. Talk to your doctor about what to expect from Wegovy to learn more.
Wegovy is not used to treat either type 1 or type 2 diabetes. Wegovy is recommended for long-term weight control in some individuals. (For further information, check the section above under “Wegovy for weight reduction and weight control.”)
However, semaglutide (the active ingredient in Wegovy) is also available under the trade names Ozempic and Rybelsus. Ozempic and Rybelsus are both medications used to treat type 2 diabetes. There is presently no approved version of semaglutide for treating type 1 diabetes.
Consult your doctor if you want to use different kinds of semaglutide to treat your diabetes.
It’s unlikely. It is unknown if Wegovy is safe or effective when used with other weight reduction and control medications. Consult your doctor before using Wegovy with any drugs, vitamins, herbs, or weight-loss products.
Wegovy should be taken in conjunction with a diet reduced in calories and frequent exercise. Some folks may also benefit from behavioural therapy or dietician advice. Along with Wegovy, see your doctor about alternative safe methods to control your weight.
Other medications for weight reduction and control are available. Some may be more suitable for you. If you’re looking for an alternative to Wegovy, consult with your doctor. They may advise you on different drugs that may be beneficial to you.
Examples of other drugs that may be used for weight loss and weight management include:
- bupropion and naltrexone (Contrave)
- liraglutide (Saxenda)
- orlistat (Alli, Xenical)
- phendimetrazine (Bontril PDM)
- phentermine (Adipex-P, Lomaira)
- phentermine and topiramate (Qsymia)
