Is Mounjaro available in the UK with a private prescription?

Can I get Mounjaro for weight loss on the NHS?

Who makes Mounjaro and what else do they produce?

Mounjaro is manufactured by Eli Lilly & Company, a global pharmaceutical firm that also produces medications such as Zepbound (US brand name for tirzepatide weight loss treatment).

Is Mounjaro a GLP-1 medication?

Yes, Mounjaro is a GLP-1 receptor agonist. It mimics natural gut hormones to control blood sugar, suppress appetite, and support weight loss. It also targets GIP, another hormone, which may make it more effective than other GLP-1 medications like Wegovy.

Is there a difference between Mounjaro and tirzepatide?

No, Mounjaro is the brand name and tirzepatide is the active ingredient.

Can I use Mounjaro if I have high blood pressure?

Possibly. Your doctor will assess your medical history before prescribing Mounjaro. Some early studies suggest it may help lower blood pressure, but always follow medical advice.

How quickly can I lose weight using Mounjaro?

Clinical trials show that users may lose up to 20% of their body weight over 72 weeks. Results vary depending on your lifestyle, starting weight, and response to treatment.
If you're not seeing progress, there could be other factors that are preventing it.

Can Mounjaro cause fatigue or make you feel tired?

Tiredness isn’t an official side effect, but some people do report feeling fatigued. This may be due to changes in diet, metabolism, or as a symptom of type 2 diabetes.
If it continues, get medical advice.

Does Mounjaro cause erectile dysfunction?

There is no known link between Mounjaro and erectile dysfunction. If you experience ED while using it, speak to your doctor to explore other possible causes.

Can Mounjaro cause hair loss?

Mounjaro doesn’t directly cause hair loss, but rapid weight loss can trigger temporary shedding (telogen effluvium). To reduce this risk:

• Get enough protein

• Take supplements if needed

• Avoid crash dieting

If hair loss persists, speak with your doctor.
