Best Semaglutide Alternatives for Weight Loss UK 2024: Expert Guide by Dr. Emma Richardson
Hi, I’m Dr. Emma Richardson. If you’re exploring weight loss options in the UK and have heard about semaglutide, you’re likely wondering whether it’s the right choice or if there are better alternatives. Semaglutide has made waves recently for its impressive results, but it’s not the only game in town. Today, I’m here to walk you through some of the best semaglutide alternatives for weight loss in 2024 — plus some pros and cons, backed by science and UK health guidelines.
Why Consider Alternatives to Semaglutide?
Semaglutide, a GLP-1 receptor agonist originally developed for type 2 diabetes, has been repurposed for weight loss with remarkable effectiveness. The NHS acknowledges its role in managing obesity, especially alongside lifestyle adjustments (NHS Obesity Treatment). But it’s not suitable or accessible for everyone. Some may experience side effects, others may find the prescription process challenging or costly, and some might prefer non-injectable options.
That’s why exploring alternatives makes sense—whether you want something oral, different mechanisms of action, or just another route to achieve sustainable fat loss.
Top Semaglutide Alternatives for Weight Loss UK 2024
Below is an overview of some popular and medically reviewed alternatives available or relevant in the UK market.
| Medication | Type | Mode of Administration | Typical Weight Loss | FDA/NHS Status | Notes |
|---|---|---|---|---|---|
| Liraglutide (Saxenda) | GLP-1 receptor agonist | Daily injection | 5-8% body weight | Approved by NICE for obesity treatment | Similar to semaglutide but requires daily injections; well-studied (NICE Guidance) |
| Orlistat (Alli, Xenical) | Pancreatic lipase inhibitor | Oral capsules | 3-5% body weight | Available OTC and prescription in the UK | Blocks fat absorption; gastrointestinal side effects common (NHS Orlistat Info) |
| Phentermine | Appetite suppressant (stimulant) | Oral | 5-10% body weight | Not licensed in the UK; prescribed off-label in rare cases | Short-term use only; risk of dependency and side effects; consult a specialist |
| Setmelanotide (Imcivree) | MC4 receptor agonist | Injection | Varies, based on genetic obesity causes | FDA-approved for rare genetic obesity; limited UK availability | Used for rare genetic disorders; specialized treatment (FDA Announcement) |
1. Liraglutide (Saxenda)
Liraglutide works similarly to semaglutide by mimicking the hormone GLP-1, helping reduce appetite and improve blood sugar regulation. It requires daily subcutaneous injections, which some find less convenient than the once-weekly semaglutide. Clinical trials report an average 5-8% weight loss over 1 year, making it a solid alternative. It’s approved by NHS and NICE guidelines for certain patients struggling with obesity.
2. Orlistat (Alli, Xenical)
If you prefer an oral medication, orlistat might be your go-to. It works by inhibiting fat absorption in the gut, so dietary fat doesn’t get absorbed but is excreted instead. While the average weight loss is modest (3-5%), orlistat has the advantage of being available over the counter (Alli) or via prescription (Xenical) in the UK. Keep in mind gastrointestinal side effects like oily stools can occur, so follow dietary guidance closely.
3. Phentermine
Phentermine is an appetite suppressant commonly used in the US but not licensed in the UK. It’s sometimes prescribed off-label for short periods under specialist care. Because it is a stimulant with potential dependency risk, it’s not widely recommended here—but it’s worth knowing about, especially if you consult with weight loss specialists.
4. Setmelanotide (Imcivree)
This is a newer, more niche alternative, primarily for rare genetic obesity syndromes linked to MC4 receptor mutations. It targets a different pathway than GLP-1 agonists and has shown promising results in specific populations. Currently, its use in the UK is limited and highly specialized.
Beyond Medications: Combining Approaches for Best Results
Weight loss medications are most effective when combined with sensible lifestyle changes—balanced nutrition, regular physical activity, and psychological support. The NHS Healthy Weight Programme offers excellent resources to complement any pharmacological approach.
Frequently Asked Questions (FAQ)

Are there any oral alternatives to semaglutide?
Yes. Orlistat is an oral option approved and available in the UK. Phentermine is also oral but less common and not officially licensed here. Research into oral GLP-1 receptor agonists is ongoing but not yet widely accessible.

How long does it take to see weight loss results with these medications?
Most weight loss medications require consistent use over several months. Initial effects can be seen within 12-16 weeks, but sustained results depend on adherence and lifestyle factors.
