Mounjaro Weight Loss Injection FAQs

If you’re exploring medically supported options for weight loss, Mounjaro weight loss injections may have come up during your research. At Junction Pharmacy, we offer private weight management support for those who want to lose weight safely and sustainably, under the guidance of qualified professionals.

We’re frequently asked about Mounjaro, how it works, and whether it’s the right treatment option for different patients. Below, we’ve answered some of the most common questions to help you feel more confident about what to expect.

What Are Mounjaro Weight Loss Injections?

Mounjaro is the brand name for tirzepatide, a once-weekly injectable medication that is used to support weight loss in adults who meet certain medical criteria. It was initially developed to help manage type 2 diabetes, but clinical trials found that many patients also experienced significant and sustained weight loss, especially when combined with healthy lifestyle changes.

Unlike earlier medications such as Saxenda, Mounjaro works by mimicking two natural hormones in your body (GLP-1 and GIP), both of which help regulate appetite, insulin, and digestion.

How Quickly Does Mounjaro Work?

The rate at which people see results with Mounjaro weight loss injections can vary, but many patients begin to notice a difference within the first 4 to 6 weeks.

During the early stages of treatment, you’ll be started on a lower dose, which is gradually increased over several months. Most patients start to feel fuller more quickly, have fewer cravings, and consume smaller portions without feeling deprived.

Substantial weight loss tends to occur over a period of 12 to 24 weeks, especially when injections are combined with improved eating habits, regular physical activity, good hydration, and sleep.

Remember, weight loss is a journey. At Junction Pharmacy, we help manage your progress and expectations every step of the way.

Can I Stop Taking Mounjaro Once I’ve Lost Weight?

This is a very common question. Technically, yes, you can stop taking Mounjaro, but the decision should be made in consultation with a healthcare professional.

Mounjaro helps regulate the hormones that affect hunger and food intake. Once you stop using the injections, those hormonal signals can return to their baseline levels, which may lead to increased appetite and potential weight regain over time.

That’s why we strongly recommend a gradual and supported transition, ideally after reaching a stable weight. This might include stepping down your dose, integrating long-term lifestyle changes, and developing strategies to maintain your progress without medication.

Our team at Junction Pharmacy provides ongoing support even after you finish your treatment plan.

Do I Need a Prescription for Mounjaro?

Yes, Mounjaro is a prescription-only medicine in the UK. You cannot buy it over the counter. At Junction Pharmacy, we offer private consultations to assess whether Mounjaro is suitable for you. This includes reviewing your BMI, medical history, and weight loss goals.

We make the process simple and discreet. If you’re eligible, we can prescribe Mounjaro and arrange for safe collection or delivery. Throughout your treatment, you’ll be able to check in with our team to adjust your plan as needed.

Is Mounjaro Available on the NHS?

As of now, Mounjaro is not widely available on the NHS for weight loss. While it may be prescribed for managing type 2 diabetes in some areas, access for weight loss is limited and often subject to strict criteria or local funding decisions.

That’s why many people choose to access Mounjaro weight loss injections privately through reputable pharmacies and clinics like ours. You’ll receive faster access, personalised care, and continuity of support.

Are There Side Effects?

As with any medication, Mounjaro can cause side effects in some people. The most common are mild and include:

• Nausea

• Diarrhoea

• Constipation

• Reduced appetite

• Tiredness or dizziness

These effects often reduce as your body adjusts to the medication and the dosage is increased gradually. Our pharmacists are here to guide you through managing any side effects, adjusting your dose if needed, and ensuring your treatment remains both safe and effective.

Can I Use Mounjaro If I’m Already on Other Weight Loss Medication?

If you’ve tried another injectable like Wegovy or Saxenda, we’ll assess your experience during your consultation. Some patients find that Mounjaro works better for them, particularly if they didn’t respond as well to other medications, or if they plateaued with earlier treatments.

You should never combine weight loss medications unless under direct medical supervision. At Junction Pharmacy, we ensure a safe and considered approach when switching or starting any treatment.
