Metformin works to manage type 2 diabetes by assisting the body in using insulin. Natural balance is restored by controlling sugar levels after meals.
Metformin belongs to a group of medicines called biguanides, known for lowering sugar levels in the blood. It is the active compound in several Australian medicines such as Glycomet, Istamet, Metaglip, Jentadueto, Actoplus Met, Kombiglyze XR and Metformin with Glyburide.
Metformin works mainly on how the liver and muscles handle sugar. It is taken as a tablet or extended-release form, and its effect shows up over days to weeks rather than instantly.
Metformin is commonly used to help manage type 2 diabetes, a condition where the body does not use insulin effectively. It may also be recommended for pre-diabetes, where blood sugar is higher than normal but not yet diabetic. Some doctors prescribe it for polycystic ovary syndrome (PCOS) to improve hormonal balance and reduce excess weight. In some cases, it is added when other diabetes medicines are not enough to keep sugar in check.
Metformin tells the liver to produce less glucose and helps muscle cells absorb more glucose, which lowers the amount circulating in the bloodstream.
Because it does not increase insulin, the risk of low blood sugar (hypoglycaemia) is lower than with some other diabetes medicines, producing a steadier, more balanced sugar level throughout the day.
If you are pregnant, planning a pregnancy, or breastfeeding, discuss metformin with your health professional, as special care may be needed. People with kidney or liver problems, significant heart failure, or a history of severe dehydration should also use it cautiously. Heavy alcohol use can increase the chance of a rare but serious condition called lactic acidosis, so limiting alcohol is advisable. Certain medicines, especially some contrast agents used for imaging, some diuretics, and other diabetes drugs, can interact with metformin. Always check the label that comes with your specific medication for detailed interaction information.
Older adults, people with reduced kidney function, and those taking multiple medicines that affect kidney clearance are more likely to notice side effects. Individuals who drink large amounts of alcohol or have heart failure may also experience problems more often.
Keep metformin tablets in a cool, dry place away from direct sunlight. Extended-release forms should not be crushed or chewed, as this can change how the medicine works. Some products are meant for short-term use, while others are taken long-term to keep blood sugar under control. Strength and directions can differ between brands.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
