Can you switch from weight loss injections to pills?

Most people who are using a weight loss injection should be able to switch to weight loss pills.

Before starting any new weight loss medication, you’ll first need to meet certain medical criteria. Having a BMI of 30 or over, or of 27 or above if you have a weight-related condition, like diabetes, are two such criteria.

But if you’ve been using a weight loss injection for a while, your BMI might have dropped below this. If this is the case, your clinician might look at your starting weight before you begin treatment, to see if they think switching to weight loss pills is the best option for you.

If you’re maintaining a healthy weight while using a weight loss injection, your clinician might discuss why you want to switch to using weight loss pills. And before they recommend any options, they’ll talk about your diet, activity levels, and your weight loss targets.

They’ll also look at your medical history, including existing medications you take that might cause interactions when combined with weight loss pills. They’ll also consider whether or not it’s safe for you to fast for specific periods of time, which weight loss pills (like oral Wegovy) require you to do.

If your clinician is happy for you to start using them, they’ll help you develop a plan to switch from injections to pills.

So what are the main reasons people make the switch?

Convenience

For some people, self-administering injections can be daunting. Even if you’ve gotten used to injecting yourself when using a GLP-1 pen, it might still feel painful to do and can sometimes cause bruising.

Switching to a weight loss pill completely removes any needle phobias or doubts about how to correctly use your treatment. Swallowing a tablet each day can be easily incorporated into your daily routine, and might make your dosage schedule feel simpler too.

Travel and storage

All GLP-1 injections, such as Wegovy, are stored between 2°C and 8°C. This means they need to be kept in the fridge at all times at home, and often need to be packed into gel ice packs to stay cool when delivered to you.

Storing injections in the fridge at home might be easy enough, but they can sometimes take up valuable space. If you’re in rented or shared accommodation, you may feel like you don’t want them to be visible for other people to see.

Because weight loss pills are stored at room temperature, you can keep them virtually anywhere. There’s a much lower risk of spoilage, and they’re a much simpler option for travelling as you don’t need to worry about keeping them chilled.

Less fluctuations

When you’re using a weekly weight loss injection like Wegovy, you typically experience a spike of the medication in your system in the first few days after taking your dose. But towards the back end of the week, when your next injection is almost due, it’s normal for those levels to dip.

This fluctuation can make it harder to regulate your appetite consistently, and might mean that you feel like the medication is wearing off. Because you take tablets like the Wegovy pill daily, there should be a more even level of semaglutide in your bloodstream, which can mean you’re less likely to experience hunger and ‘food noise’ between doses.
