Wegovy is a prescription-only weight loss injection containing semaglutide, a GLP-1 receptor agonist. It’s designed to help reduce appetite and support sustainable weight loss in people with obesity or weight-related health conditions. But who can take Wegovy, and is it suitable for you?

‍

Let’s find out. In this guide, we break down:

• NHS criteria for Wegovy prescriptions
• Private eligibility for Wegovy injections
• Who should not take Wegovy
• Common side effects and precautions
• What to expect during treatment

‍

‍

Wegovy NHS Eligibility 

You can get Wegovy through the NHS if you meet the NICE (National Institute for Health and Care Excellence) criteria:

• BMI of 35 or more, with at least one weight-related health condition (e.g., high blood pressure, heart disease, type 2 diabetes)
• BMI of 30 or more in some cases, such as those from certain ethnic backgrounds or with lower thresholds for obesity-related risks
• Enrolled in a specialist NHS weight management service (tier 3)

‍

‍

‍

Wegovy Private Prescription Eligibility 

If you don't meet the NHS criteria or simply want quicker access to Wegovy injections, you can get a private prescription from a licensed clinic such as Dr Frank's Weight Loss Clinic. 

‍

You may be suitable for private treatment if you have:

• A BMI of 27+ with a weight-related condition
• A BMI over 30, even without existing health issues

‍

Wegovy Considerations

Although Wegovy can be extremely beneficial, there are certain things to consider before - and whilst - taking it. From taking the right dosage to making long-term lifestyle changes, here are some considerations: 

‍

Take The Appropriate Dose

You must adhere to the right dosage instructions when taking Wegovy. You will gradually increase your dose over the span of 16-17 weeks until you reach the full maintenance dose. Here is the typical dosing schedule: 

• 0.25 mg once a week until week 4 
• 0.5 mg once a week until week 8 
• 1 mg once a week until week 12
• 1.7 mg once a week until week 16
• 2.4 mg once a week - maintenance dose 

‍

Only change your dose when instructed to do so by your doctor. Your doctor may adjust your dose if you experience side effects. 

‍

Always Consult a Healthcare Professional 

Always consult your doctor when - and before - taking Wegovy. Your doctor will determine whether it’s a right fit for you, and manage your dosage as needed. They will also advise you on the correct injection method, how to store your medication, and how to dispose of your used injections. 

‍

Wegovy is intended for long-term use, so it’s important to regularly check in with your doctor to ensure your Wegovy treatment is safe and effective throughout your course of treatment. 

‍

Consider Side Effects

Wegovy side effects are usually mild and short-term, but it’s important to be aware of them so you can prepare. Some potential side effects may include: 

• Vomiting
• Constipation
• Nausea
• Headache
• Fatigue
• Stomach pain
• Diarrhoea

‍

Most side effects will subside when your body adjusts to the medication. If side effects persist or worsen, consult with your doctor. 

‍

Consider Potential Long-Term Effects

On the box, Wegovy warns about the potential risk of thyroid C-cell tumours, including medullary thyroid carcinoma (MTC). A large-scale study found that Wegovy did not significantly increase the risk of thyroid cancer compared to other diabetes medications.

‍

Serious side effects are uncommon with Wegovy, but some potential long-term effects may include gallbladder problems, increased heart rate, low blood sugar, and pancreatitis. 

‍

Make Lifestyle Changes

Wegovy gives you the opportunity to create and maintain healthy habits to help you lose weight, and keep it off for good. The medication becomes much more effective when you combine it with lifestyle changes, including diet and exercise. Learn more about how long Wegovy takes to work here. 

‍

When you engage with a treatment plan - including regular follow-ups, you are far more likely to see positive results. Work closely with your doctor to achieve your goals.

‍

Who Should Not Take Wegovy?

Wegovy is a highly effective weight loss injection for many, but it’s not suitable for everyone. Speak to your doctor if:

• You have severe liver disease or severe kidney disease 
• You have pre-proliferative or proliferative diabetic retinopathy and are taking insulin (this would be managed more carefully in conjunction with your ophthalmologist)
• You’re taking other medications that could cause drug contraindications 
• You are at risk of suicidal behaviour

‍

 If you fall into any of the following categories, you should not take Wegovy:

‍

You Are Under The Age of 18 or Over 75

The safety and efficacy of Wegovy have not been studied thoroughly in children and elderly adults, so we will not prescribe Wegovy to patients under the age of 18. The same applies to adults over the age of 75. 

‍

You Are Allergic to Semaglutide or Other Ingredients

If you have a known allergy to semaglutide (the active ingredient in Wegovy) or any of the other ingredients in the medication, you should not take it. Allergic reactions can range from skin rashes to severe symptoms like anaphylaxis, which can be life-threatening. Some signs may include: 

• Swelling of lips, tongue, throat or face
• Trouble swallowing
• Trouble breathing
• Itching 
• Rash
• Rapid heartbeat
• Feeling faint

‍

If you think you are having an allergic reaction to Semaglutide, seek medical attention immediately.  

‍

You Are Pregnant or Breastfeeding

Wegovy is not recommended during pregnancy or if you’re planning to become pregnant in the near future. This is because the effects of Wegovy on an unborn baby are not well studied, and there is a potential risk of harm. We also don’t recommend that you take Wegovy while breastfeeding, as it’s unclear if the medication can pass into breast milk and affect your baby.

You Have a History of Certain Thyroid Conditions

Avoid taking Wegovy if you or someone in your family has a history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN 2). These rare thyroid conditions could increase your risk of serious complications when using GLP-1 receptor agonists like semaglutide.

‍

You Are Experiencing Diabetic Ketoacidosis (DKA)

Do not use Wegovy during an episode of diabetic ketoacidosis (DKA) – a potentially life-threatening condition common in people with type 1 diabetes. DKA requires urgent medical treatment, and taking Wegovy during this period can interfere with stabilisation efforts.
