Weight Loss Treatments

Mounjaro

Mounjaro is a weekly injection that may help reduce hunger, control cravings, and support weight loss. Available at Hayshine Pharmacy.

What is Mounjaro?

Mounjaro is a prescription-only injection used once a week to help with weight loss. It contains the active ingredient tirzepatide, which mimics two natural gut hormones (GLP-1 and GIP) that play a key role in regulating appetite, digestion, and blood sugar levels.

How does Mounjaro work?

Mounjaro mimics two natural hormones, GLP-1 and GIP, which help regulate appetite and blood sugar after eating. By acting on these signals in the brain, it helps reduce hunger, increase feelings of fullness, and slow digestion.

This can make it easier to eat less, manage cravings, and lose weight steadily over time. It also supports better blood sugar control, which can be helpful for those with type 2 diabetes.

What to Expect from Mounjaro Treatmenta

Mounjaro is injected once a week using a pre-filled pen. Your pharmacist will explain how to use it properly, and your dose will usually start low and increase gradually to help reduce side effects.

Some people may experience mild side effects at first — such as nausea, constipation or tiredness. With the right support and consistency, Mounjaro can become a valuable tool in your long-term weight management plan.

How long does Mounjaro take to work?

Everyone responds differently, but most people start to notice a change in appetite or portion sizes within the first few weeks. As your body adjusts and the dose increases gradually, noticeable weight loss typically begins within 4 to 8 weeks, with continued progress over time. It’s not a quick fix — but it’s designed to support steady, long-term results when used consistently.

How to Use an Mounjaro Pen

A Step by Step Guide

Check the Pen

Make sure you're using the correct pen and dose. Check the expiry date and that the liquid inside is clear and colourless.

Wash Your Hands and Prepare the Needle

Wash your hands, then remove the pen cap. Attach a new needle by screwing it on, and remove both needle caps.

Prime the Pen (if needed)

If it's your first use or a new pen, turn the dial to the starting dose and press until a drop appears at the tip to ensure the pen is working.

Select Your Dose

Turn the dose selector to the dose prescribed by your healthcare provider.

Choose Your Injection Site

Use your stomach, thigh, or upper arm — making sure to rotate sites each time to avoid irritation.

Inject the Dose

Press the pen firmly into your skin at a 90-degree angle. Hold the dose button down until the dose counter returns to 0, then keep the pen in place for 6 seconds before removing it.

Dispose of the Needle

Carefully replace the outer needle cap, unscrew the needle, and dispose of it in a sharps bin or as instructed.

Store the Pen

Put the cap back on and store your pen safely. Keep unused pens in the fridge (but don’t freeze them).

Is There an Alternative to Mounjaro?

Ozempic vs Mounjaro

We also offer Ozempic, another once-weekly injection that’s widely used for weight loss. While Mounjaro works on two hormones (GLP-1 and GIP), Ozempic targets one (GLP-1). Some people respond better to one than the other, depending on their body and health history.

Our team at Hayshine Pharmacy can help you compare both options and decide which treatment is the best fit for your weight loss journey.

It's important to remember:

All weight loss treatments must be prescribed following a consultation to ensure they are safe and appropriate for you. Results can vary from person to person, and no medication guarantees weight loss. These treatments should always be used alongside a balanced diet, regular physical activity, and under the supervision of a healthcare professional.
