This medication should not be administered to certain patients. Firstly, it should not be used in patients who have previously shown allergic reactions to this medication or those with myasthenia gravis. Moreover, since this medication contains lactose, it should not be given to patients with genetic issues such as galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption. It should be administered with caution in patients with a history of drug allergies or liver dysfunction as liver function may worsen. Patients must be closely monitored during use as severe shock can occur rarely, and treatment should be stopped immediately and appropriate care sought if any unusual symptoms appear. Liver function tests may show elevated levels, so liver status should be checked periodically, and treatment should be discontinued if abnormalities occur. It may also affect kidney function, so monitoring for proteinuria or changes in blood test results is necessary. Hypersensitivity reactions such as anemia, skin rashes, and itching may occur, necessitating caution. Central nervous system symptoms may include insomnia, drowsiness, headache, limb paralysis, and rigidity or tremors. Gastrointestinal symptoms may include nausea, vomiting, loss of appetite, abdominal pain, diarrhea, and constipation. Urogenital effects may manifest as urinary retention or incontinence. There may be systemic symptoms such as weakness, dizziness, and reduced muscle tension. Rarely, facial flushing, sweating, and swelling may occur. This medication may cause serious allergic reactions such as anaphylaxis, angioedema, and severe skin conditions like toxic epidermal necrolysis syndrome; if symptoms such as fever, erythema, blisters, itching, conjunctival injection, or stomatitis occur, treatment should be discontinued immediately and medical consultation sought. Fatigue, staggering, and drowsiness may arise during medication use, and in such cases, dosage should be reduced or treatment stopped. This medication can cause drowsiness and decreased attention, so driving or operating dangerous machinery should be avoided. Caution is advised when taken with similar medications or certain muscle relaxants as adjustment disorders may occur. The safety during pregnancy has not been established; women who may become pregnant should only use it when the benefits outweigh the risks, and lactating women should avoid use or discontinue breastfeeding if it is taken. Safety in children has not been sufficiently confirmed, so caution is needed for use. Elderly patients may have reduced physical function and should use the medication carefully, with dosage adjustments when necessary.
