Side Effects

While Metformin is generally safe and effective, some patients may experience side effects, especially when starting the medication. Common side effects include:

• Nausea
• Vomiting
• Diarrhoea
• Stomach cramps or bloating
• Metallic taste in the mouth

Lactic acidosis, a condition resulting from a buildup of lactic acid in the blood, is a rare but serious side effect. Symptoms include:

• Unusual muscle pain
• Severe fatigue
• Shortness of breath
• Slow or irregular heartbeat

If you notice any of these symptoms, stop taking the medication and seek immediate medical attention.

Warnings

1. Medical History: Tell your doctor if you have kidney or liver problems, heart disease, or a history of alcohol use, as these conditions may increase the risk of lactic acidosis.
2. Surgery or Imaging Tests: Stop taking Metformin temporarily before undergoing surgery or tests involving iodine-based contrast dyes, as these can impair kidney function.
3. Metformin is generally safe to use during pregnancy, but only under medical supervision. Consult your doctor if you are breastfeeding.
4. Drug Interactions: Certain medications, such as diuretics, corticosteroids, and some blood pressure drugs, may interact with Metformin. Inform your doctor about all medications you are taking.
5. Alcohol: Avoid excessive alcohol consumption as it increases the risk of lactic acidosis.

How to Take

• Dosage: Follow your doctor’s prescribed dose. Typical starting doses range from 500 mg to 1,000 mg daily, gradually increasing based on your response.
• With Meals: Take Metformin with meals or immediately after to reduce the risk of stomach upset.
• Swallow Whole: For extended-release tablets, do not crush, chew, or break them.
• Consistency: Take it at the same time every day to maintain stable blood sugar levels.
