The video, presented by two speakers, provides a concise nursing‑focused overview of metformin. It begins with a brief introduction and a call to download a free pharmacology cheat sheet. Speaker B then details metformin’s generic and trade names, its classification as a biguanide antidiabetic, and its primary indication for type 2 diabetes mellitus. The drug’s three mechanisms of action are explained: decreasing hepatic gluconeogenesis, reducing intestinal glucose absorption, and increasing peripheral cellular glucose uptake, all leading to lower blood glucose levels. Common adverse effects—gastrointestinal upset (bloating, diarrhea, nausea, vomiting) and the rare but serious risk of lactic acidosis—are described, along with a reminder to monitor for hypoglycemia. The speaker outlines nursing assessments and monitoring priorities: regular blood glucose checks, quarterly HbA1c measurements, and labs to detect lactic acidosis (lactate, ketones, pH, electrolytes). Contraindications and precautions are highlighted, including renal impairment, liver disease, sepsis, dehydration, heavy alcohol use, and the need to hold metformin before procedures involving iodinated contrast, often substituting insulin temporarily during hospitalization. Patient education points cover proper dosing, reporting signs of lactic acidosis, routine glucose self‑monitoring, diet, exercise, and follow‑up labs. The video concludes with promotional messaging for a nursing medication database and a membership community, encouraging viewers to like, comment, and subscribe.
Chapters
In this video, you will learn the side effects of Metformin and Metformin's mechanism of action. Now, pharmacology can be challenging, to say the least, in nursing school, so we're going to break it down super simple so that you can finally understand it. So don't worry, my friend, you don't need to figure everything out alone anymore for nursing school. No, no, no. We are here to help you every step of the way. And if you need more help with learning pharmacology in nursing school, be sure to downlo this free pharmacology cheat sheet that we have for you that walks you through how to learn pharmacology step by step. Now, the link is down below in the description for you to get that now hit that subscribe button and click the notification bell and let's dive in.
All right, let's talk about Metformin. So the generic name is metformin and the trade names are Fortimet, Glucophage, Glumnetza, Glucophage xr, and Ryomet. The pharmacologic class of metformin is a biguinate, and the therapeutic class is an antidiabetic. Now, the indications for metformin, or what metformin is used for, is to control type 2 diabetes mellitus. There are three primary ways that metformin works in the body. It decreases the amount of glucose that the liver makes. It decreases the amount of glucose that's absorbed through the intestines, and. And it makes the cells take up more insulin and therefore take up more glucose as well. So by decreasing the amount of glucose the liver makes, decreasing the amount that the intestines absorb, and causing the cells to take up more glucose, the blood glucose level is reduced. The therapeutic effect of all of this is that it decreases the blood sugar level. Some side effects that can be associated with metformin are some GI upset, like bloating, diarrhea, nausea, and vomiting. Again, remember, it's decreasing the amount of glucose that's absorbed in the small intestines. So any interference with the intestine can cause some GI upset. It's often associated with diabetes, and its goal is to reduce blood sugar levels. So we want to be cautious of hypoglycemia as well. And lactic acidosis can also be a concern, although it is pretty rare. For your nursing assessment for metformin, it's important that we assess the patient's blood sugar levels in their body. So your number one assessment should be for hypoglycemia you're always going to want to be on the lookout for signs and symptoms of hypoglycemia. These would be things like shakiness, headache, dizziness, cool and clammy skin, sweating, hunger, tachycardia and confusion. Lactic acidosis can also cause chills, dizziness, muscle pain, low blood pressure, diarrhea, weakness and trouble breathing, so you'll want to be on alert for those symptoms as well. Now, since metformin is supposed to reduce the patient's blood glucose level, we want to make sure it's working effectively. You'll want to check their blood glucose levels periodically and their glycated hemoglobin levels or hemoglobin A1C at least every three months to monitor their blood sugars. And like we said before, lactic acidosis is a concern for patients taking metformin. So you'll need to check their lactate levels to ketone levels, blood ph, electrolytes and glucose levels for lactic acidosis, too. Now, metformin should not be used if the patient is at risk for lactic acidosis. So if they have other conditions like liver problems, sepsis, dehydration, or if they consume a lot of alcohol, they should not be taking metformin because it will further increase this risk. Since metformin is excreted by the kidneys, it can cause lactic acidosis if the kidneys aren't functioning properly. So if your patient has any renal impairment, you should question a metformin order. And the last contraindication we'll talk about is any procedure that the patient would be given iodine contrast dye, like CT scans, X rays, MRI scans, or some cardiac procedures. Metformin and contrast dye don't play nice together. So if the patient is taking metformin and is given contrast eye, they're more likely to develop lactic acidosis. So a little fun fact for you. If your patient has type 2 diabetes and usually takes metformin at home, they will be more than likely temporarily switch to insulin during a hospitalization, just in case they need imaging. So if your patient asks why they're getting insulin, that's why, just tell them the metformin can interact with some other imaging procedures they do at the hospital. So in case they need imaging done, it's better to be safe than sorry. Patient education is going to revolve around teaching your patient to take the medication exactly as prescribed by their doctor. Report any signs of lactic acidosis. So things like chills, dizziness, muscle pain, low blood pressure, diarrhea, weakness, and trouble breathing and general diabetes management so things like regularly checking their blood glucose levels, urine ketones and eating a balanced diet as well as exercising regularly. For nursing considerations, be sure to monitor your patient for signs of lactic acidosis and hypoglycemia and also make sure your patient is doing proper follow up with their blood work to monitor their hemoglobin A1C levels for long term blood sugar control.
