Foundayo (Orforglipron) Side Effects: What Should You Expect?
Weight Loss
Foundayo is a weight loss tablet that’s recently been approved by the MHRA in the UK. It is a glucagon-like peptide 1 (GLP-1) receptor agonist like Wegovy, Ozempic, and Mounjaro but is taken as a pill rather than an injection.
This medication works in a similar way to other GLP-1 medications by slowing down stomach emptying, improving blood sugar control, and reducing hunger cues, helping you to feel less hungry and eat fewer calories. This, along with regular exercise, helps you to lose weight.
Like other GLP-1s, Foundayo is only effective when combined with a balanced, reduced-calorie diet and regular physical activity. It can help people lose an average 10-15% of their body weight after 72 weeks of taking the highest dose. Although this is slightly less than the average with GLP-1 injections, many people prefer the ease of taking a tablet rather than an injection.
As with any medication, Foundayo can come with side effects, and you may be wondering: What are the side effects of Foundayo? In this article, we’ll explore common Foundayo side effects like nausea, vomiting, and diarrhoea, discuss more serious side effects, and when to seek help.
Common digestive side effects
Digestive or gastrointestinal side effects are some of the most common associated with Foundayo.
These include:
Nausea
Constipation
Diarrhoea
Vomiting
Heart burn
Abdominal pain
Bloating
Burping
Passing wind
Acid reflux
In clinical trials, between 60-69% of patients taking Foundayo experienced digestive side effects compared to just 37% of people taking non-active placebo pills. Around 6% of people taking the highest dose had to stop the medication due to these gastrointestinal side effects.
Around 60% of the time, digestive side effects are mild, but they can be severe in around 4% of people experiencing these side effects.
When they improve
The digestive Foundayo side effects tend to be worse when you first start the medication. They usually improve as your body adapts to Foundayo being in your system, but this can take a few days or weeks.
You may also notice your side effects flare up again after each dose increase, but they should settle down after your body becomes used to the new higher dose. Again, this may take a little while.
Once you reach your maintenance dose and are no longer increasing your dose every month or so, you may well find your side effects level off.
How to manage digestive side effects
Digestive side effects often improve by themselves with time as your body gets used to the medication.
In some cases, you may need to speak to your prescriber about reducing your dose down. Some people’s bodies need longer to get used to dose increases or are unable to tolerate higher doses.
If your symptoms don’t get better with time and are severe or are significantly interfering with your daily life, you may need to stop Foundayo. After stopping the medication, your side effects should disappear. In this case, a healthcare professional may suggest an alternative weight loss medication instead.
For many people, mild digestive side effects like nausea or heartburn can be managed with a few simple changes such as:
Eating small meals regularly throughout the day
Opting for low-fat, easily digestive foods
Drinking plenty of water
Not lying down right after eating
If you have vomiting or diarrhoea, it’s important to avoid becoming dehydrated. If these symptoms continue for more than a few days, it’s important to seek medical advice.
Other common side effects
Other common side effects of Foundayo that impact 5% or more of people taking the medication include:
Headaches
Fatigue/tiredness
Hair loss
Again, these side effects are mostly mild and can be managed by waiting for your body to adjust to the medication, reducing the dose, taking pain killers, and/or resting.
Serious side effects
Serious side effects of Foundayo are much rarer, but they can happen. If you’re experiencing any of these symptoms, it’s important to see medical attention.
Allergic reactions
Allergic reactions are a severe side effect that can happen when taking any medication. They can be mild with just a rash and/or itchy skin or can be more severe with swelling affecting the face and airway.
Always seek medical attention if you’re worried you’re experiencing an allergic reaction and call 999 in an emergency. If you know you are allergic to any of the ingredients found in Foundayo, do not take it.
Low blood sugar
Low blood sugar events are uncommon but have been reported in some people with type 2 diabetes who are take Foundayo along with other medications for diabetes like insulin. Severely low blood sugar is rare.
Signs of low blood sugar include hunger, sweating, dizziness, irritability, and very low blood sugar can cause shaking, confusion, dizziness, and even loss of consciousness. Your diabetes doctor should talk to you about what to look out for and what to do if you have low blood sugar.
Pancreatitis
GLP-1 medications can increase the risk of inflammation of the pancreas (pancreatitis), and this may be true with Foundayo.
In clinical trials, patients taking Foundayo seemed to be at an increased risk of developing pancreatitis. The data shows that if 10,000 people were followed up for 1 year, 14 taking Foundayo would be expected to develop pancreatitis compared to 4 taking a placebo.
The main symptom of pancreatitis is severe stomach pain (especially in the top part of the abdomen) that doesn’t go away and is worse after eating or moving. It may also come with back pain, a fever, bloating, bruising on the stomach, a fast heartbeat, and/or difficulty breathing.
Gallbladder problems
Gallstones have been reported in 1% of people taking Foundayo in clinical trials (compared to 0.7% of people taking a placebo) while gallbladder inflammation was reported in 0.4% (vs. 0.3% in patients on a placebo).
Signs to look out for include pain in the right upper stomach, nausea, vomiting, and/or fever.
Kidney problems
Acute kidney problems have been reported in some people taking Foundayo, especially those who have experienced vomiting/diarrhoea and become dehydrated or have underlying kidney issues.
Usually, acute kidney problems are picked up with a blood test, but people can also feel tired, short of breath, confused, nauseous, have swollen feet/legs, or notice they’re urinating less often.
Diabetic retinopathy (eye problems)
Foundayo may worsen an eye problem known as diabetic retinopathy in people with type 2 diabetes. This is usually temporary.
Signs of diabetic retinopathy include worsening eyesight, blurred vision, floaters in your vision, and/or difficulty seeing in low light.
Thyroid tumours
In studies involving mice and rats, GLP-1 medications have been shown to slightly increase the risk of a type of thyroid cancer known as C-cell tumours. Foundayo was not shown to have this effect in rodent studies.
However, the medication leaflet carries a warning that the medication should be avoided by people with an increased risk of these types of tumours.
Signs of thyroid cancer to look out for include a mass in the neck, difficulty swallowing or breathing, persistent hoarseness.
Increased risk during surgery with general anaesthesia
When receiving a general anaesthetic (being put to sleep for surgery), the muscles in your throat and neck relax and don’t work as well as normal. This means in some cases the stomach contents can come up into the throat and go down into the lungs, which can lead to a type of aspiration pneumonia.
As Foundayo slows down how quickly the stomach empties, food and drink stay there for longer. This means it can increase the risk of aspiration pneumonia.
It’s important to tell your doctor you are taking Foundayo and they should be able to make adjustments to minimise the risk of this happening during surgery. Fasting before surgery minimises the risk of this.
A full list of all the side effects is available in the Foundayo medication insert.
When to seek help
If you’re worried you’re experiencing any severe or worrying medication side effects, it’s always best to seek advice from a medical professional. If you have chest pain, a fast heart rate, are struggling to breathe, or in any other emergency situation, call 999.
For less severe side effects, it’s always worth discussing them with your prescriber if they’re affecting your daily life.
Safety precautions
Some people may be at increased risk of side effects when taking Foundayo because of an underlying medical condition or other medications they take.
It’s always important to discuss your medical history with a healthcare professional before starting Foundayo or any new medication. That way, you’ll know it’s safe for you to take.
