Metformin, while generally safe and effective, can cause side effects. Common ones include nausea, diarrhea, and stomach upset. These usually lessen as your body adjusts to the medication. Drink plenty of water and consider taking Metformin with food to minimize gastrointestinal issues.
Less Common but Important Side Effects
Less frequent but more serious side effects include lactic acidosis, a rare but potentially life-threatening condition. Symptoms include muscle pain or weakness, unusual fatigue, and difficulty breathing. Seek immediate medical attention if you experience these.
Vitamin B12 deficiency can also occur with long-term Metformin use. Regular blood tests can monitor this. Your doctor may recommend B12 supplements if needed. A metallic taste in your mouth is another possible side effect.
Allergic reactions, while uncommon, can manifest as skin rash, itching, or swelling. Stop taking Metformin and contact your doctor immediately if you suspect an allergic reaction.
If you experience persistent or worsening side effects, or notice any new symptoms, contact your healthcare provider for guidance. They can assess your situation and adjust your treatment plan accordingly.
