Wegovy Weightloss Injection

What Is Wegovy?

Wegovy is a weight loss medicine designed to help you lose weight by helping to regulate your appetite and reduce cravings. When this is combined with healthy eating and regular exercise it can be a very effective medicine in helping you to successfully lose weight. The active ingredient in Wegovy is called semaglutide, this is the ingredient that tells your brain you’re full and helps to reduce cravings.

With one injection a week, it’s a quick and easy medicine to use. Our team will talk you through how to inject wegovy and make sure you’re comfortable with the treatment.

What Is Mounjaro?

Mounjaro is a weekly self–injectable pen to help with sustained weight loss. It contains tirzepatide which works by regulating blood sugar, helping to reduce appetite and prevent cravings. This combined with healthy lifestyle changes can result in sustained weight loss.

Mounjaro is different to Wegovy in that it combines GLP-1 and GIP hormones to have more effective results for weight loss. Our team will review your current weight, your goals and any other health conditions you have to decide if Mounjaro is right for you.

About Our Weight Loss Treatments

If your BMI is consistently over 30 and you’ve been struggling to lose weight on your own then using weight loss medication can be the solution for losing weight and keeping it off. Taking these medications for a year can mean a loss of total body weight of 3% to 12% more than that lost with lifestyle changes alone. While that might not seem like a lot losing 5% to 10% of your total weight can be massively beneficial and reduce your risk of complications from excess weight.

To access these medicines you need to have a doctor review your current weight, health and lifestyle to determine if these solutions are right for you. Fill in our form here and a member of our team will review your answers and if it’s relevant will prescribe an appropriate medicine for you. We can then delivery these medications to you or you can collect these medicines from your nearest Crest Pharmacy.

Various prescription weight loss treatments are available, catering to individual preferences and needs, offered by Crest Pharmacy.

These options, available in tablet or injectable pen forms, are aimed at assisting in achieving weight loss objectives.

Weight Loss Injections:

Crest Pharmacy provides two injectable prefilled pens: Wegovy and Mounjaro.

– Wegovy: This injectable medication is for overweight or obese adults, taken weekly. It functions by mimicking a hormone that targets appetite-regulating brain areas, promoting a feeling of fullness with less food consumption.

– Mounjaro: Similar to Wegovy, Mounjaro, a once-weekly injection containing tirzepatide, aids in weight loss by reducing hunger and prolonging satiety. It is recommended to incorporate lifestyle changes such as a balanced diet and exercise regimen alongside its use.

– Saxenda: An injectable pen formulation containing liraglutide, Saxenda, reduces hunger when taken once daily. It typically begins working within 1 to 2 days, with noticeable results expected within a few weeks.

Weight Loss Tablets:

Crest Pharmacy offers four types of weight loss tablets: Orlistat, Xenical, Mysimba, and Alli.

– Orlistat: This tablet alters fat digestion, leading to decreased fat absorption. It is most effective when consumed with low-fat meals, up to three times daily, with visible weight loss results expected within 2 weeks.

– Xenical: A branded version of Orlistat, Xenical operates similarly, requiring up to three daily doses with fat-containing meals. Weight loss effects are typically noticeable within 2 weeks of treatment initiation.

– Mysimba: This tablet suppresses appetite, aiding in food intake control and reducing cravings. It is administered at a gradually increasing dose and should start showing effects within 1 to 2 days, reaching full efficacy within weeks.

– Alli: Available over-the-counter, Alli capsules work by inhibiting fat absorption from meals, ideally taken up to three times daily with fat-containing meals. They are effective when combined with a healthy diet and regular exercise.

Is it possible to purchase weight loss treatment online?

Yes, you can obtain prescription weight loss treatment online through reputable providers like Crest Pharmacy. The process is straightforward: you’ll answer a few health-related questions, which will be reviewed by a doctor to ensure suitability before prescribing. In cases where a treatment isn’t suitable, alternatives may be offered.

Your prescribed weight loss treatment will be discreetly delivered to your doorstep. If you have any queries or require guidance regarding your treatment, you can message an online doctor through your account at no extra cost.

Can weight loss treatment be bought over the counter?

Prescription weight loss treatments like Wegovy, Mounjaro, orlistat, Xenical, or Mysimba are not available over the counter. However, over-the-counter options such as alli capsules are accessible. alli contains 60mg of the active ingredient orlistat, also found in Xenical and generic orlistat tablets but at a higher dosage.

Is weight loss treatment available through the NHS?

Yes, weight loss treatment may be accessible through the NHS. To explore this option, you’ll need to schedule an appointment with your GP, who will assess your suitability for the treatment.

Each weight loss treatment contains a unique active ingredient, resulting in slightly different side effects. While these effects typically subside within a few days, they may persist for longer periods. If side effects become bothersome or persistent, it’s advisable to consult your doctor.

Common side effects associated with most weight loss treatments include:

– Abdominal pain
– Diarrhoea or constipation
– Headache
– Nausea or vomiting
– Taste changes
– Fatigue
– Potential risk of gastroparesis (delayed gastric emptying)

Refer to your medication packet for a comprehensive list of side effects.

It’s important to recognize that individuals may experience side effects differently, and rapid weight loss itself can also lead to side effects such as changes in skin appearance, such as stretch marks, or alterations in menstrual regularity.

Duration of Side Effects:

While most side effects should diminish within a week of medication initiation, this timeline varies from person to person. Weight loss medications like Saxenda or Mysimba are typically administered at lower initial doses, gradually increased over time to mitigate common side effects like nausea or vomiting.

Managing Side Effects:

If you experience side effects, attempt to manage them at home whenever possible. For common issues like nausea and vomiting, opt for smaller, non-oily, non-greasy, non-spicy, and non-fatty meals. Stay hydrated, rest, and consider over-the-counter pain relievers like paracetamol for headaches.

For orlistat and Xenical, oily or fatty stools and increased bowel movements are common side effects. Decreasing fat intake and evenly distributing fat consumption throughout the day may alleviate these effects. If side effects persist, your doctor may consider reducing your dosage until your body acclimates to the medication. In most cases, side effects associated with weight loss treatments tend to resolve naturally.

Seeking Medical Attention:

In the event of serious side effects such as allergic reactions, immediate medical attention is necessary. Contact emergency services at 999 or proceed to A&E without delay.

Is a certain BMI required to receive weight loss treatment?

Yes, a specific BMI is typically necessary for weight loss treatment eligibility. This is because such treatment may not be effective or safe unless an individual is overweight or obese. Generally, a BMI of over 27 or 28 is required, depending on the prescribed medication. Additionally, having certain medical conditions affecting weight, such as diabetes, is often a prerequisite.

Individuals with a BMI exceeding 30 may qualify for weight loss treatment, even without a medical condition affecting their weight.

For those uncertain of their BMI, our BMI calculator can be used to determine it accurately.


Several medical conditions may render weight loss treatment unsuitable for certain individuals. Factors determining suitability vary based on the specific treatment. Consulting a doctor before starting any weight loss medication is crucial, especially if one has:

– Liver or kidney problems
– Inflammatory bowel disease (IBD)
– Thyroid disease
– Heart issues
– Epilepsy or a history of seizures
– Anxiety or other mental health conditions
– Chronic malabsorption syndrome (difficulty absorbing nutrients)

Weight loss treatment is not recommended for individuals under 18, pregnant or breastfeeding individuals, or those allergic to any medication ingredients.

Medication Interactions:

Certain medications may interact with weight loss treatment, potentially compromising its effectiveness or safety. It is imperative to inform your doctor about any other medications you are taking, particularly:

– Epilepsy medication
– HIV treatment
– Mental health medications
– Heart medications like amiodarone
– Blood thinners such as warfarin
– Hypothyroidism treatments like iodine salts
– Diabetic treatments
– Parkinson’s disease medications, especially monoamine oxidase inhibitors
– Opiates
– Steroids
– Malaria treatments
– Infection treatments like antibiotics
– Asthma treatments such as theophylline

Prescription weight loss treatments are effective aids for weight loss, but they should complement a regimen of regular exercise and a balanced diet. While weight loss surgery may be an option for some individuals, it’s relatively rare.


Regular physical activity aids weight loss by burning calories and utilizing stored energy. Maintaining a balance between calorie intake and expenditure is crucial for weight management. Additionally, exercise can help prevent and manage certain medical conditions like diabetes, contributing to overall weight loss and health maintenance.

According to NHS guidelines, engaging in about 150 minutes of moderate-intensity exercise weekly, including activities like dancing, cycling, and brisk walking, is recommended. Alternatively, 75 minutes of higher-intensity exercise such as running and circuit training can be beneficial. Combining moderate and high-intensity exercises is optimal for weight loss. Incorporating balance and strength training activities, like weightlifting or yoga, at least twice weekly is also beneficial.


Diet plays a pivotal role in weight loss efforts. NHS guidelines suggest reducing daily calorie intake by 600 calories. For women, this typically means consuming no more than 1400 calories per day, while men should aim for around 1900 calories. Emphasising the consumption of healthy foods such as fruits, vegetables, healthy fats (e.g., avocado), whole grains, nuts, beans, and natural yogurt is essential. Conversely, limiting or avoiding sugary foods, high-fat items (especially those containing saturated fat), fried foods, crisps, white bread, and alcohol is advisable.


Weight loss surgery is an option for individuals who have struggled to lose weight through other methods, typically reserved as a last resort. Common types of weight loss surgery include gastric banding, gastric bypass, and sleeve gastrectomy. These procedures reduce stomach capacity, leading to feelings of fullness with less food intake. While surgery can aid weight loss, it requires a commitment to healthy eating for proper nutrition. Candidates for weight loss surgery typically have a BMI of over 40 or over 35 with certain medical conditions. In some cases, surgery may be considered for individuals with a BMI over 50. Despite associated risks, weight loss surgery is generally safe when recommended by a doctor. However, it’s not suitable for everyone and may not be available through NHS for all individuals.
