    Before talking about Metformin and alcohol together, it is important to know why Metformin is used. As mentioned earlier, Metformin is an oral first-line medication for Type 2 diabetes. Type 2 diabetes is a chronic condition in which our body doesn’t produce enough insulin, resulting in high glucose levels in the bloodstream. Type 2 diabetes runs in families and so is a genetic condition. It can also be caused due to bad lifestyle influences and decisions.

    Metformin is often prescribed along with insulin to maintain sugar levels. However, it is always advisable to consume Metformin along with a healthy and conscious diet and workout regime. The medicine is first tested by consuming 500 mg of it once a day following the end meal of the day. If the reactions are convincing, then another 500 mg is prescribed to be taken once a day with breakfast

    Risks Involved In The Interaction Of Metformin And Alcohol

    Lactic Acidosis

    As mentioned above, consuming too much alcohol while taking Metformin can cause a buildup of lactic acid in our bodies. Lactic acidosis is a metabolic condition in which the body overproduces lactic acid and is not able to cope up with this excessive production.

    It can also be due to improper utilization/underutilization of lactic acid. Excessive buildup of lactic acid causes immense damage to a person’s liver and kidney as they are unable to remove such huge amounts of the acid from the system.

    The chances of developing this condition during the intake of Metformin is usually rare but with the intervention of alcohol, especially the ones rich in calories and sugar, the chances are higher. Lactic acidosis may sound less dangerous but can be life threatening. The common symptoms include

    • Gut pain
    • Insomnia
    • Changes in heartbeat
    • ‘Loss of appetite
    • Constant dizziness
    • Changes in breathing pattern and swallowing
    • Vomiting and nausea

    Vitamin B12 Deficiency

    Vitamin B12, also known as cobalamin, is one of the most important water-soluble vitamins which play a vital role in metabolism. They are very important to maintain a healthy bloodstream and nerve cells. It is found abundantly in dairy products, eggs, and meat and also in vegetables like beans, Brussel sprouts, peas, and so on.

    It is common to be afflicted with this deficiency while intaking Metformin. However, consumption of Metformin and alcohol together worsens the condition and could lead to metabolism-related ailments. The common symptoms include numbness in hands and feet, memory loss, headache, anemia, and so on.


    We all know that Metformin helps in reducing blood sugar levels. However, if the dosage increases, it causes hypoglycemia, which literally means low blood sugar. So, quantity in moderation is everything.

    Occasionally, Metformin induced low blood sugar can occur due to consumption of alcohol. The reason why you shouldn’t consume Metformin and alcohol together is that the symptoms of hypoglycemia are confused due to the consumption of alcohol. In simpler words, you may not recognize the symptoms of hypoglycemia if you are drinking alcohol.

    The common symptoms of hypoglycemia include dizziness, headache, and hyperphagia (excessive hunger). The life threatening symptoms of it include

    • Nausea and vomiting
    • Nightmares
    • Increased heartbeats
    • Foggy vision
    • Lack of concentration
    • Nervousness and anxiety
    • Pale skin

    Cardiovascular risks

    Consumption of Metformin can have negative effects on cardiovascular diseases. But recent studies have shown that the intervention of alcohol makes the chances and the risks involved even higher.
