Ministry of Health fronts on ineffective oestrogen patches

The manufacturer of Estradot patches says its actively investigating reports that some of the patches are faulty - but so far testing hasn't found any defects. Women have been having problems with the oestrogen patches not sticking properly or not working. Sandoz has told RNZ it's received about 50 complaints, Medsafe says it's received 149 complaints, but there wasn't enough evidence to warrant a recall. Ministry of Health Clinical Chief Advisor Anna Skinner spoke to Ingrid Hipkiss.
