Frequently

Questions
The usual starting dose of metformin extended-release tablet is 500 mg once daily with an evening meal. Chat with Oana doctors to figure out the dosage that's appropriate for your needs.
While Metformin ER is primarily prescribed to manage blood sugar levels in people with type 2 diabetes and to address symptoms of PCOS, some patients may experience weight loss as a side effect. It's believed that Metformin can influence appetite and energy expenditure.
A single dose of metformin ER has the capability to regulate your blood sugar levels for approximately 12 hours. However, should you cease taking the medication, it typically requires around 4 days for the majority of it to be expelled from your body. This duration is largely calculated from the half-life of metformin ER and may vary based on individual health factors and genetic makeup, meaning the exact time frame could differ from person to person.
Metformin ER (extended-release) and metformin IR (immediate-release) are utilized in the treatment of Polycystic Ovary Syndrome (PCOS) to manage insulin resistance, a common condition associated with PCOS. Metformin ER is designed to release the medication gradually in your body, reducing the risk of gastrointestinal side effects commonly associated with the immediate-release form of Metformin. This slower release also means it can be taken less frequently which can improve adherence to the medication regimen.
It is commonly believed that Metformin can cause a reduction in Vitamin B12 levels, possibly by interfering with its absorption or through another mechanism. For this reason, we advise patients on Metformin to either monitor their B12 levels or take extra B12 as a precaution. However, some studies suggest there is no significant connection between Metformin use and B12 levels.
Regardless of Metformin use, it's important to maintain proper levels of Vitamin B12. For adults under 65, the easiest way to get B12 is to take at least one 2,000 mcg supplement each week or a daily dose of 50 mcg. Note that these doses are specific to cyanocobalamin, the preferred supplemental form of Vitamin B12.
As we age, our ability to absorb Vitamin B12 may decline. For those over 65, especially those on plant-based diets, supplementation should probably be increased to 1,000 mcg of cyanocobalamin daily.
B12 supplements are very cheap. Here is one option we found: 5c per 2500mcg tablet, so 5-15cents of cost per week depending on your age.
