Is there a more affordable option available with the same insulin degludec 100IU/ml formulation and pen device?

Other insulin products containing the same insulin degludec at the same strength are generally considered equivalent in how they work. But insulin is one of those medicines where I'd really discourage switching on your own - dosing needs to stay precise, and even a small difference between products can affect your sugar control. Do check with your doctor or pharmacist about what alternatives are available and suitable for you, and you can also check the platform's product listings or customer support for pricing on similar options.
