Side Effects of Metformin 500 mg: What You Need to Know
Metformin is a widely prescribed medication for the management of type 2 diabetes. It is an oral antidiabetic drug that helps to control blood sugar levels by improving insulin sensitivity. While metformin is generally well-tolerated, it is important to be aware of potential side effects that may occur with its use.
One of the most common side effects of metformin is gastrointestinal upset. This can include symptoms such as nausea, vomiting, diarrhea, and abdominal discomfort. These side effects are usually mild and temporary, and may improve over time as the body adjusts to the medication. It is recommended to take metformin with food to help reduce the likelihood of experiencing these gastrointestinal symptoms.
Another potential side effect of metformin is a decrease in vitamin B12 levels. Metformin can interfere with the absorption of vitamin B12 in the digestive system, leading to a deficiency over time. This can result in symptoms such as fatigue, weakness, and neurological issues. It is important for individuals taking metformin to have their vitamin B12 levels regularly monitored and to consider taking a B12 supplement if necessary.
Common side effects
Metformin is generally well-tolerated, but like any medication, it can cause side effects in some people. The most common side effects of metformin 500 mg include:

However, if you do experience any of these less common side effects and they become severe or persistent, it is important to seek medical attention.
Serious side effects
In some cases, metformin can cause serious side effects that require immediate medical attention. These side effects are rare, but it is important to be aware of them and seek medical help if they occur.
Some serious side effects of metformin include:
- Lactic acidosis: This is a rare but serious condition that can occur when there is a buildup of lactic acid in the body. Symptoms may include weakness, muscle pain, trouble breathing, and stomach discomfort. If you experience any of these symptoms, it is important to seek medical attention immediately.
- Allergic reactions: Some people may have an allergic reaction to metformin, which can cause symptoms such as rash, itching, swelling, dizziness, and trouble breathing. If you experience any of these symptoms, stop taking metformin and seek medical help right away.
- Hypoglycemia: Metformin can sometimes cause low blood sugar levels, especially if taken with other diabetes medications or if you skip meals. Symptoms of hypoglycemia may include sweating, shakiness, confusion, and dizziness. If you experience these symptoms, it is important to consume a source of glucose, such as a sugary drink or candy, and seek medical attention.
- Vitamin B12 deficiency: Long-term use of metformin can lead to a deficiency in vitamin B12. Symptoms of vitamin B12 deficiency may include weakness, fatigue, numbness or tingling in the hands and feet, and difficulty with balance. If you experience these symptoms, talk to your doctor about monitoring your vitamin B12 levels and possibly taking a supplement.
It is important to note that these are not all the possible side effects of metformin. If you experience any unusual symptoms or have concerns about the medication, it is important to talk to your doctor.
Allergic reactions
Allergic reactions to metformin are rare, but they can occur in some individuals. These reactions can range from mild to severe and may include symptoms such as:
- Hives or rash
- Itching
- Swelling of the face, lips, tongue, or throat
- Difficulty breathing
- Tightness in the chest
- Feeling lightheaded or faint
If you experience any of these symptoms after taking metformin, it is important to seek medical attention immediately. Allergic reactions can be serious and may require immediate treatment.
If you have a known allergy to metformin or any other medications, it is important to inform your healthcare provider before starting metformin therapy. They may recommend an alternative medication or take precautions to minimize the risk of an allergic reaction.
In some cases, individuals may develop an allergy to metformin after using it for a period of time without any previous issues. If you experience any new symptoms or changes in your health while taking metformin, it is important to notify your healthcare provider.
In rare cases, metformin may cause a severe allergic reaction known as anaphylaxis. Anaphylaxis is a life-threatening condition that requires immediate medical attention. Symptoms of anaphylaxis may include difficulty breathing, swelling of the throat or tongue, rapid heartbeat, and dizziness. If you experience any of these symptoms, seek emergency medical care or call your local emergency number.
It is important to remember that allergic reactions to metformin are rare, and most individuals can take the medication without any adverse effects. However, if you have a known allergy or experience any symptoms of an allergic reaction, it is important to seek prompt medical attention.
Metformin and lactic acidosis
One of the potential side effects of metformin is lactic acidosis. Lactic acidosis is a rare but serious condition that can occur when there is an excess buildup of lactic acid in the body. It can be life-threatening if not promptly diagnosed and treated.
Metformin, a commonly prescribed medication for type 2 diabetes, works by decreasing the production of glucose in the liver and improving the body’s sensitivity to insulin. By doing so, it helps to lower blood sugar levels. However, in some cases, metformin can cause an accumulation of lactic acid in the bloodstream.
Symptoms of lactic acidosis

The symptoms of lactic acidosis can be non-specific and may include:
- Weakness and fatigue
- Muscle pain and cramps
- Nausea and vomiting
- Difficulty breathing
- Abdominal pain
- Irregular heartbeat
If you are taking metformin and experience any of these symptoms, it is important to seek immediate medical attention, as lactic acidosis can be a medical emergency.
Risk factors for lactic acidosis
While lactic acidosis is a rare side effect of metformin, certain factors may increase the risk. These include:
- Impaired kidney function: Metformin is primarily excreted by the kidneys, so if the kidneys are not functioning properly, the drug may accumulate in the body and increase the risk of lactic acidosis.
- Dehydration: Dehydration can lead to an increase in lactic acid levels in the body.
- Use of contrast dye: Some medical procedures require the use of contrast dye, which can also increase the risk of lactic acidosis.
- Alcohol abuse: Alcohol can impair liver function and increase the risk of lactic acidosis.
- Other medical conditions: Certain medical conditions, such as liver disease or heart failure, can also increase the risk of lactic acidosis.
Preventing lactic acidosis
To minimize the risk of lactic acidosis while taking metformin, it is important to follow your healthcare provider’s instructions and monitor your kidney function regularly. If you have any concerns or experience any symptoms of lactic acidosis, it is important to contact your healthcare provider immediately.
Your healthcare provider may also recommend periodic blood tests to monitor your kidney function and lactic acid levels. It is important to stay hydrated, avoid excessive alcohol consumption, and inform any healthcare professionals about your use of metformin before undergoing any medical procedures.
