Who can switch to weight loss 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 certain weight loss pills (like oral Wegovy) require you to do, whereas options like Foundayo (orforglipron) can be taken at any time with or without food.

If your clinician is comfortable with you starting them, they’ll help you develop a plan to switch from injections to pills.

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 36°F and 46°F (2°C and 8°C). This means they need to be kept in the refrigerator at all times at home, and packed into gel ice packs to stay cool when delivered to you.

Storing injections in the refrigerator at home might be easy enough, but they can sometimes take up valuable space. If you’re in a rental or shared housing, 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 traveling as you don’t need to worry about keeping them chilled.

Fewer 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 toward 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 Foundayo or the Wegovy pill daily, there should be a more even level of the active medication in your bloodstream, which can mean you’re less likely to experience hunger and ‘food noise’ between doses.

Are weight loss pills more effective than injections?

How effective weight loss pills are will vary widely from person to person. This is because weight loss doesn’t tend to follow a linear path, which means there’s no standard treatment or dose schedule that guarantees results.

Until recently, GLP-1 injections like Zepbound and Wegovy were considered far more effective for average weight loss when compared to weight loss tablets such as Orlistat.

In one 68-week study of patients using a 2.4 mg dose of weekly semaglutide, it was shown to help them lose 14.9% of their starting weight. In a different study, which looked at the effectiveness of Orlistat, patients lost just 8.5% of their initial weight after using when using it daily for a year.

But recent oral GLP-1 options like Foundayo (orforglipron) and higher doses of weight loss tablets like the Wegovy pill have significantly bridged the gap between the effectiveness of injections versus pills. For instance, clinical studies with Foundayo demonstrate significant average weight loss over 72 weeks, while in one 71-week study, the 25 mg maintenance dose Wegovy pill helped patients achieve an average of 16.9% weight loss after 64 weeks.

How do I make the switch?

Your clinician will help you switch from using a GLP-1 injection to taking a weight loss pill instead.

You’ll usually be advised to wait until half of the medication you’re currently taking has left your system, but this often differs between medications. For medications like Saxenda, this might be achieved in a few days, but weekly weight loss injections like Zepbound and Wegovy tend to have a longer half-life.

Whichever injection you’re using, your clinician will tailor a switching plan to your needs, and decide which dose you should start on once you begin using weight loss pills like Foundayo or oral Wegovy.

Will I need a new prescription for weight loss pills?

Yes, you will need a new prescription when you start using weight loss pills.

If you do decide to switch from weight loss injections, you’ll be starting a whole new treatment plan altogether. Even though the active ingredients in both your old medication and your new one might be the same (if you switched from Wegovy injections to pills for example) or completely different (such switching from Zepbound to Foundayo), the formulation you use and your dosage schedule will be completely different. So it might be helpful to think of it as a different treatment altogether, which requires a fresh prescription.
