What now you took two weeks of simvastatin 80mg instead of 40mg?

Taking simvastatin at a higher dose than prescribed can increase the risk of side effects, particularly muscle-related issues like myopathy or rhabdomyolysis. It's important to consult your healthcare provider as soon as possible to discuss your situation and any potential symptoms you may experience. They may recommend monitoring your liver function and muscle health, and adjusting your dosage as needed. Always follow your prescribed medication regimen to ensure safety and effectiveness.
