i received a letter from him saying that he felt it not wise to put me on Byetta as it was not licensed to use with insulin and the fact i had been on insulin too long. This was a total contradiction to what he told me verbally, and i now feel so disappointed. is this true about the licensing? Could soe one give me more info on Byetta and how it works on a understandible level than a medial jargon one? a sweet thank you..x
Hi Elixers,
Unfortunately it is true that Byetta is not licensed anywhere in the world for use with insulin - but this is simply because the manufacturers (Eli Lilly) designed it only for use with Type-2s so never trialled it with insulin patients. Strange that a drug manufacturer would not realise that many type-2s are on insulin! However, despite this, for the last year it has been quite widely prescribed in the US for insulin dependent Type-2s and with no adverse reactions. I have heard of only a few cases in the UK where a diabetician has prescribed a byetta/insulin combination and these are where the patient is unable to tolerate any of the normal oral type-2 meds. I fear that it is very unlikely that you would be prescribed byetta WITH insulin, but of course it could be prescribed INSTEAD OF insulin. This would have to be in conjunction with an oral med, again because it is only licenced in the UK as a secondary treatment - so you must also take an oral med (like metformin) as your primary treatment.
Just for information, byetta works in 5 ways:
- it triggers the pancreas to start producing insulin in response to eating a meal
- it stops the pancreas from releasing glucagon, which in turn stops the liver from producing un-needed glucose
- it slows down the rate at which food is digested, which makes for a slower increase in blood sugar, giving the insulin a better chance of dealing with the "traffic"
- it helps to reduce appetite by sending messages to the brain to say "don't need any more food thanks, I'm full"
- it reduces liver fat content, so reduces the triglycerides that are responsible for leaving deposits in the arteries that lead to heart attacks.
It appears that Symlin (also an Eli Lilly product), as suggested by Sarah, has some of the same properties as byetta and was developed for use with insulin-dependent patients:
- it slows digestion
- it sends messages to the brain to say you are full
- it inhibits glucagon production.
However, I can find absolutely no mention of it (or under its generic name "Pramlintide") in any of the UK medical sites, or on the NICE website, so I can only assume that it is not yet available in the UK.
