At Right Medicine Pharmacy, we offer trusted weight management support across Scotland, helping people access safe, effective treatments backed by clinical advice.

Whether you’ve tried dieting and exercise without seeing the results you hoped for, or you’re interested in learning more about how prescription medication might help, this guide will walk you through everything you need to know before starting orlistat 120 mg – and why Mounjaro might be a better fit for you!

What Is Orlistat and How Does It Work?

Orlistat is a prescription-only weight loss medication designed to support adults with a body mass index (BMI) of 30 or above, or a BMI of 28 or more with related risk factors such as high blood pressure or type 2 diabetes.

The 120 mg version is the licensed strength for prescription use. It works in the digestive system by preventing the body from absorbing around 30 percent of the fat you eat. Instead, this undigested fat passes through your body in your stool. By blocking fat absorption, orlistat helps reduce your overall calorie intake, which in turn supports gradual and sustained weight loss.

It’s important to note that orlistat is not an appetite suppressant and doesn’t affect your brain’s hunger signals. If you are looking for a popular and reliable appetite suppressant, Mounjaro might be a better option for you. Get in touch with our team to discuss your options with our dedicated team.

Who Can Take Orlistat 120 mg?

Orlistat 120 mg is suitable for adults aged 18 and over who meet specific clinical criteria. Typically, your pharmacist or GP will assess your BMI, lifestyle, and overall health before prescribing it.

You may be a good candidate for orlistat if:

• –> You have a BMI of 30 or more.

• –> Your BMI is 28 or higher and you have weight-related conditions such as high cholesterol or hypertension.

• –> You are committed to making long-term changes to your diet and activity levels.

Before starting any weight loss treatment, a consultation will also explore any existing medications you are taking, as orlistat can affect the absorption of certain vitamins and other treatments such as warfarin or ciclosporin.

How Much Weight Can You Lose?

The amount of weight lost with orlistat varies from person to person, depending on how well they stick to the recommended diet and lifestyle plan. Studies show that when combined with a reduced-calorie diet, orlistat can increase weight loss by up to 50 percent compared to diet alone.

On average, patients who follow the full programme can expect to lose five percent or more of their body weight over a 12-week period. For example, someone weighing 100kg may lose 5kg or more if they maintain the treatment plan and make the necessary changes to their eating habits.

If you don’t lose at least five percent of your starting body weight within the first three months, your pharmacist or prescriber may recommend stopping the treatment. This is why it’s vital to follow the programme properly and seek guidance when needed.

Possible Side Effects to Expect

Because orlistat works by blocking fat absorption, the side effects are primarily digestive. These can include:

• –> Oily or fatty stools

• –> Urgent or increased need to go to the toilet

• –> Flatulence with oily spotting

• –> Abdominal discomfort or pain

• –> Loose stools or diarrhoea

These effects are most common in the early weeks of treatment and usually settle as your body adjusts and you adapt your diet. Reducing your intake of high-fat foods can significantly reduce the chance of unpleasant side effects.

It’s also worth noting that orlistat can reduce the absorption of fat-soluble vitamins such as A, D, E, and K. Your pharmacist may recommend taking a multivitamin supplement at bedtime to ensure your nutritional needs are met.

Tips for Getting the Best Results

To get the most out of orlistat 120 mg, it’s essential to treat it as part of a wider weight loss strategy. Here are our top tips for success:

1. Stick to a lower-fat, calorie-controlled diet

Aim to keep each meal below 15 grams of fat. Choose grilled, baked, or steamed foods and reduce intake of fried items, cheese, and creamy sauces.

2. Don’t skip meals

Orlistat should be taken three times a day with main meals containing fat. If you skip a meal or eat one with very little fat, skip that dose of orlistat too.

3. Exercise regularly

Build up to at least 150 minutes of moderate exercise per week. Walking, swimming, or cycling can all support better results.

4. Take a multivitamin

Because orlistat affects fat-soluble vitamin absorption, taking a supplement at least two hours after your last dose of the day can help prevent deficiencies.

5. Track your progress

Use a food diary or weight tracking app to monitor your journey. This can help you stay motivated and identify areas for improvement.

What if Orlisat isn’t Right for Me?

While orlistat 120 mg can be highly effective for some individuals, others may benefit from alternative medications depending on their health profile and weight loss goals. One such option is Mounjaro (tirzepatide), a newer injectable treatment that mimics the actions of gut hormones to regulate blood sugar and appetite. Unlike orlistat, which works in the digestive system, Mounjaro affects metabolic processes to help reduce hunger and increase feelings of fullness. It’s currently licensed for managing type 2 diabetes but is being used off-label for weight loss in some clinical settings. If you struggle with insulin resistance, appetite control, or have not seen results from orlistat, Mounjaro might be a more suitable option.
