An interesting question.
I was given Pioglitazone last month. This was after I requested to be taken off of Januvia due to the risks of cancer.
My friend works for a law firm in New York and is dealing with those involved in a class action against the manufacturers of Januvia, so although there is only some medical information linked to potential cancer risks, I am not willing to chance it.
According to my GP, there is very little oral medication left for me to try as I appear to be someone who gets side effects easily!
Pioglitazone became my daily medication along with SR Metformin.
Result? A weight gain of 10 pounds in four weeks. No change to my diet and exercise. I did not see any improvement to my levels.
So, back to the doc on Monday of last week.
The rapid weight gain did not surprise him and agreed with me that it appears to be counter productive to take a drug which is known to cause weight gain when losing weight is the ideal scenario! No more Pioglitazone for me.
I was prescribed 5mg Forxiga.
Levels have already improved with numbers easily falling to Nice guidelines.
Side effect so far is the need to pee frequently. So that required a bit of getting used to.
Since Monday, I have lost 6 lbs in weight, so that is a good thing.
I understand that all meds come with the inherent risks of side effects. It is up to each individual to weigh up the risks v benefits and do enough research to satisfy ourselves.
So for me weight gain was a deal breaker, for you it may be not so important.
So my advice is do some research of your own so that when you next visit your Gp or nurse you will feel a bit more in control.
Good luck with whatever path you choose.
