With the launch of Wegovy tablets in the UK, patients now have two semaglutide-based options for weight loss: a once-daily tablet and a once-weekly injection.
Both forms of Wegovy are designed to support weight loss by reducing appetite, increasing fullness and helping patients stay in a calorie deficit. But while they contain the same active ingredient, they are not identical in how they fit into day-to-day life.
What do Wegovy tablets and injections have in common?
Both Wegovy tablets and Wegovy injections contain semaglutide, a GLP-1 medicine that mimics a hormone involved in appetite regulation.
This can help patients:
- Feel fuller for longer
- Eat smaller portions
- Experience fewer cravings
- Support meaningful weight loss over time
Both are intended for adults who meet clinical criteria for weight management and both should be used alongside lifestyle changes such as improved diet and increased physical activity.
The biggest difference: daily tablet vs weekly injection
The main difference is convenience and routine.
Wegovy tablets
- Taken once daily
- Must be taken on an empty stomach
- Must be taken with plain water only
- You must wait 30 minutes before eating, drinking or taking other medication
Wegovy injections
- Taken once weekly
- Can be taken at any time of day
- No fasting rules before use
- Must be stored correctly and used as an injection pen
So the real question is not just “which one works better?” but “which one fits your life better?”
Wegovy tablets may be better if you hate needles
For many patients, the biggest selling point of Wegovy tablets is obvious: no injections.
If the thought of using a weight loss pen every week puts you off treatment altogether, a tablet may feel much more manageable. It can also feel more familiar for patients who are used to taking tablets but not injectable medicines.
Wegovy injections may be better if you want less day-to-day hassle
On the other hand, the injection may be easier if you do not want to think about treatment every single morning.
A once-weekly injection can be simpler for patients who:
- Have unpredictable mornings
- Already take multiple morning medicines
- Struggle with strict fasting rules
- Prefer a weekly routine instead of a daily one
Do Wegovy tablets work as well as injections?
Both are designed to deliver semaglutide, and both can be effective for weight loss when used correctly. The exact response will vary from person to person, but the key point is that the medicine only works if you can stick to it properly.
A tablet that you forget or cannot take correctly may not be better than an injection you can reliably use every week. Likewise, an injection is not ideal if you avoid taking it because you dislike needles.
What dose do Wegovy tablets start at?
Wegovy tablets are usually started at 1.5mg once daily, then gradually increased if clinically appropriate until a maintenance dose of up to 25mg once daily.
The dose is stepped up to help reduce the chance of side effects and to allow the body to adjust to semaglutide.
What side effects do they share?
Because both treatments contain semaglutide, they share many of the same side effects. These may include:
- Nausea
- Vomiting
- Diarrhoea
- Constipation
- Stomach discomfort
- Headache
- Tiredness
The injection can also cause local skin irritation around the injection site, which obviously is not an issue with tablets.
Which option should you choose?
There is no single “best” option for everyone. The right choice depends on your routine, your preferences and what you are most likely to follow properly.
Wegovy tablets may suit you if:
- You do not want injections
- You can follow strict daily dosing instructions
- You prefer taking tablets over using pens
Wegovy injections may suit you if:
- You want a once-weekly treatment
- You do not want to plan around fasting every morning
- You prefer fewer doses overall
Final thoughts
The arrival of Wegovy tablets in the UK is a big step because it gives patients more choice. Some people will prefer the familiarity of a daily tablet. Others will still find the weekly injection easier.
The best treatment is not the one that sounds best on paper. It is the one that is clinically appropriate for you and that you can actually stick with long term.
If you are considering Wegovy tablets or Wegovy injections, make sure you use a regulated UK pharmacy and complete a proper medical consultation before starting treatment.
