Pharmacist shares one time when metformin users might need 'temporary pause'

Pharmacist shares one time when metformin users might need 'temporary pause' More than three million people take metformin for type 2 diabetes but it can come with side effects More than three million people take metformin for type 2 diabetes with more than 26 million prescriptions dispensed every year. While there are several potential side effects listed with the medication, not everyone gets them, and according to the NHS, most should ease within weeks as the body gets used to it. Now a pharmacist has set out the potential problems people might face - and what they can do about them. And the expert has also shared one time that people might have to "temporarily pause" their treatment while one particular problem settles down. Posting on TikTok, Raj Patel, who describes himself as the "straight talking pharmacist", explains what metformin is and how it works. he says: "Think of your liver as a sugar tap. Even when you're not eating, it releases sugar into your blood. And if you have type 2 diabetes, that tap releases more sugar than your body needs. "Metformin helps turn it down. It also helps the insulin that you make work better, so sugar can move out of your blood and into your cells, where it can be used for energy." He goes on to warn about some side effects those taking the medication might face - and what to do if they do. The NHS lists common side effects as: - feeling sick (nausea) or being sick (vomiting) - diarrhoea - tummy pain - loss of appetite - a change to the way things taste - vitamin B12 deficiency, which can make you feel very tired Nausea and diarrhoea The pharmacist explains: "Nausea and diarrhoea can happen, especially around starting treatment. Taking it with meals and a gradual prescribed dose increase can help. "If symptoms persist or disrupt your day. Ask whether the dose schedule or a modified release preparation needs reviewing. Do not increase, swap, or abandon treatment yourself." B12 deficiency He says: "Metformin can also lower vitamin B12. New pins and needles, unusual tiredness, or a sore red tongue deserve a review. "They do not prove B12 deficiency. Ask whether a blood test is appropriate. Testing is advised when deficiency is suspected, and periodic checks may suit people with risk factors. You can usually continue metformin while low B12 is treated if it remains suitable." When might I have to pause my treatment? The expert said there was one time you might need to take a temporary pause on treatment - but only after seeking advice from your medical team. He said: "If you are vomiting, have diarrhoea, or have a high fever, get prompt advice from your diabetes team, pharmacist, or NHS 111 about your sick day plan. "Dehydration may mean a temporary pause is needed. Following an existing clinical plan, ask when to restart. Do not wait for a routine review if you cannot keep fluids down."
