This medication can cause serious muscle-related side effects, such as myopathy or rhabdomyolysis. These side effects may include muscle pain, muscle tenderness, and muscle weakness, with a significant increase in creatine kinase levels in the blood. The risk is notably higher when taken in high doses, so caution is required. This drug should not be given to certain patients. For example, individuals allergic to its components, those with active liver disease or unexplained persistent elevation of liver enzymes, pregnant or breastfeeding women, and patients taking specific medications should avoid using this drug. Patients with severe muscle weakness or ocular muscle weakness should use this drug with caution as symptoms may worsen. It is important to inform a doctor immediately if muscle pain or weakness occurs while taking this medication. Moreover, liver function abnormalities may occur, so regular liver function tests are necessary, and careful monitoring is essential if there is a history of liver disease. This medication can interact with various drugs; therefore, if taking other medications, it is crucial to inform the doctor or pharmacist. The risk of muscle diseases may increase when this drug is taken in combination with certain antifungals, antibiotics, antivirals, immunosuppressants, or some heart medications, so caution is advised. Pregnant women or women planning to become pregnant must not use this drug, and if pregnancy is confirmed, the medication should be discontinued immediately. Nursing mothers should also stop breastfeeding while taking this medication. The safety and efficacy of this drug have not been sufficiently established in elderly or pediatric patients, hence caution is warranted. In case of overdose, there is no specific antidote; general treatment and supportive care will be provided.
