Overview
Use of metformin to treat diabetes now expanded to patients with moderately reduced kidney function
Recommendations for patients with kidney impairment updated in product information
On 13 October 2016, the European Medicines Agency (EMA) concluded that metformin-containing medicines can now be used in patients with moderately reduced kidney function (GFR [glomerular filtration rate] = 30–59 ml/min) for the treatment of type 2 diabetes. The product information for these medicines will be updated to revise the current contraindication and give information about doses, monitoring and precautions in patients with reduced kidney function.
The recommendations were the result of a review by EMA of metformin-containing medicines following concerns that current scientific evidence does not justify a contraindication in patients with moderate reduction of kidney function. The current product information also varies between countries and products in the EU and is no longer consistent with clinical guidelines.
Metformin may increase the risk of a rare but serious complication called lactic acidosis, which occurs when naturally produced lactic acid builds up in the blood faster than it can be removed. Currently, the product information states that metformin must not be used in patients with reduced kidney function because these patients are considered to be at a higher risk of developing lactic acidosis as their kidneys do not remove metformin efficiently enough.
However, after considering the scientific literature, clinical data, epidemiological studies and clinical guidelines from medical bodies, EMA concluded that the large patient population with moderately reduced kidney function can benefit from use of metformin. Clear dosing recommendations and monitoring before and during treatment aim to minimise any possible increased risk in these patients. The contraindication for patients with severely reduced kidney function will remain (GFR less than 30 ml/min).
Companies marketing metformin-containing medicines will be requested to closely monitor and analyse future lactic acidosis cases and report these during upcoming periodic safety reviews in order to follow up on any changes in the frequency of this side effect. The product information for metformin- containing medicines will be updated to reflect the new recommendations and to ensure that the same advice is given to all patients in the EU.
