These are the most common (affecting more than 1 in 10 people) side effects of Vipdomet:
- Stomach ache
- Diarrhoea
- Loss of appetite
- Nausea
- Vomiting
It’s also important to note that long-term use of metformin (one of the ingredients in Vipdomet) is well-known to cause vitamin B12 deficiency, which can lead to extreme tiredness, mouth ulcers, and pins and needles. If you start to notice any of these symptoms while taking Vipdomet, let your clinician know.
When to seek urgent medical help:
- If you develop signs of lactic acidosis (a very rare but life-threatening emergency that’s associated with metformin). Symptoms include muscle cramps, severe tiredness, and breathing difficulties.
- Like all DPP-4 inhibitors, alogliptin comes with a small risk of pancreatitis. Seek help straight away if you get severe, persistent stomach pain that radiates to your back.
