Frequently Asked Questions
Why is metformin still the first-line drug for type 2 diabetes?
Metformin has 60+ years of safety data, lowers HbA1c effectively, does not cause hypoglycaemia or weight gain, reduces cardiovascular risk, and costs under $10/month as a generic.
What is metformin ER and is it better than regular metformin?
Metformin extended-release (ER/XR) is taken once daily and causes less GI side effects (nausea, diarrhoea) than immediate-release. Most patients who struggle with regular metformin tolerate ER well.
Does metformin cause B12 deficiency?
Yes — long-term metformin use reduces vitamin B12 absorption in ~30% of patients. Annual B12 testing is recommended, especially for patients on metformin for >4 years or those with neuropathy.
Can metformin be used for PCOS without diabetes?
Yes — metformin is used off-label in PCOS to improve insulin sensitivity, regulate menstrual cycles, and reduce androgen levels. It is often combined with lifestyle change and hormonal therapy.
What does metformin cost through Script Unlock?
Metformin is one of the cheapest medications in existence — typically $4–$10/month. Script Unlock pharmacies offer competitive cash pricing and can supply both IR and ER formulations.
