What are Foundayo and Wegovy tablets?
Both Foundayo and Wegovy tablets contain semaglutide, a GLP-1 receptor agonist. This is the same active ingredient used in weight loss injections, but in tablet form.
Semaglutide works by mimicking a hormone your gut naturally produces. It slows how quickly your stomach empties, increases feelings of fullness, and helps regulate appetite signals in your brain. The result is that most people eat less without having to consciously restrict food or fight hunger.
Both medications are MHRA-approved for weight management in adults with a BMI of 27 or higher (or 30 or higher if you have no weight-related health conditions).
The key difference between the two is not the medication itself, but how you take it.
Foundayo: daily tablet
Foundayo is a once-daily tablet. You take it by mouth, on an empty stomach, at least 30 minutes before food or drink.
The starting dose is usually 3 mg per day. Your prescriber will increase this gradually over several weeks, moving up to 7 mg, 11 mg, or 14 mg depending on how you respond and tolerate the medication.
Because you take Foundayo every day, you need to remember to take it at the same time each morning. Some people find this routine helpful. Others find daily medication less convenient than a weekly injection or tablet.
Foundayo reaches a steady level in your body fairly quickly, which means the appetite-suppressing effect builds up over days rather than weeks.
Wegovy tablets: weekly tablet
Wegovy tablets are taken once a week. You swallow the tablet on an empty stomach, at least 30 minutes before food or drink.
The starting dose is 0.25 mg per week. Your prescriber will increase this gradually, typically moving to 0.5 mg, 1 mg, 1.7 mg, and then 2.4 mg per week.
Because Wegovy is dosed weekly, you only need to remember to take it once every seven days. Some people find this easier to stick with. You also have more flexibility about which day of the week you choose.
Wegovy takes longer to build up in your system than Foundayo, so the full appetite-suppressing effect may take several weeks to develop.
How to choose between them
Clinical suitability comes first. Both medications are suitable for the same people: adults with a BMI of 27 or higher, or 30 or higher without weight-related health conditions. If you have type 2 diabetes, thyroid disease, a history of pancreatitis, or severe gastrointestinal disease, speak to your prescriber before starting either medication.
Dosing preference is the main practical difference. If you prefer a simple daily routine and want the appetite effect to build quickly, Foundayo may suit you. If you prefer to take medication once a week and do not mind a slower build-up, Wegovy tablets may be easier to fit into your life.
Cost and supply. Check the current pricing and availability on the clinic website, as this can change.
Side effects are the same. Both medications cause the same side effects because they contain the same active ingredient. The most common are nausea, vomiting, constipation, and diarrhoea. These are usually mild and tend to improve over time as your body adjusts.
Side effects and risks
Both Foundayo and Wegovy tablets can cause nausea, vomiting, constipation, diarrhoea, dizziness, and headache. Nausea is most common in the first few weeks and often eases as your body adjusts.
Less common side effects include pancreatitis (inflammation of the pancreas), gallbladder problems, and changes in how your body processes other medications.
If you are pregnant, breastfeeding, have type 2 diabetes, a history of thyroid cancer or thyroid disease, a history of pancreatitis, severe gastrointestinal disease, or are under 18, speak to your prescriber before starting or continuing either medication.
If you experience severe abdominal pain, persistent vomiting, or signs of an allergic reaction, contact your prescriber or seek medical advice straight away.
Common questions
Can I switch from Foundayo to Wegovy tablets or vice versa?
Yes, you can switch between them. Your prescriber will advise on the best way to do this and how to adjust your dose. Switching usually takes a few weeks to manage safely.
Which one causes fewer side effects?
Both medications cause the same side effects because they contain the same active ingredient. Individual experience varies, but the type and frequency of side effects are similar. How quickly you build up the dose, and how your body adjusts, affects how you feel more than which tablet you choose.
Do I need to take Foundayo on a completely empty stomach?
Yes. Foundayo must be taken on an empty stomach, at least 30 minutes before food or drink. This helps your body absorb it properly. Wegovy tablets have the same requirement.
How much weight will I lose?
Clinical trials show that people taking semaglutide lose an average of 10 to 15 percent of their starting body weight over about a year, though results vary widely. Weight loss depends on your starting weight, how well you tolerate the medication, your lifestyle, and how long you take it. Your prescriber will discuss realistic expectations for you.
What happens if I miss a dose of Foundayo?
If you miss a daily dose, take it as soon as you remember, unless it is almost time for your next dose. Do not double up. If you miss a weekly dose of Wegovy, take it as soon as you remember, then continue with your usual schedule the following week. Speak to your prescriber if you are unsure.
Can I take these tablets if I have type 2 diabetes?
Both medications can be used in people with type 2 diabetes, but you must discuss this with your prescriber first. They will need to check your blood sugar control and may adjust other diabetes medications. Do not start either medication without speaking to your prescriber if you have diabetes.
Do these tablets work without diet and lifestyle changes?
Semaglutide helps by reducing appetite and increasing fullness, but it works best alongside healthy eating and physical activity. The medication removes the constant hunger that can make lifestyle changes hard to stick with, but it is not a replacement for them.
