What should be monitored with thiazolidinediones?

Thiazolidinediones can cause delayed-onset hypoglycaemia, especially in combination with other oral hypoglycaemic drugs, weight gain and fluid retention. The fluid retention may precipitate heart failure so careful monitoring of weight gain and peripheral oedema is required.

Both OAM therapies were well tolerated.
