This medication should not be administered to certain patients. For example, individuals allergic to this medication or patients with myasthenia gravis should not use it. Additionally, this medication contains lactose, so patients with genetic problems that prevent lactose digestion should not take it. Such conditions include galactose intolerance, lactase deficiency, and glucose-galactose malabsorption. Patients with a history of drug hypersensitivity or liver dysfunction should use this medication with particular caution, as there may be a risk of worsening liver function. While taking this medication, serious allergic reactions such as shock may rarely occur, so symptoms should be carefully monitored. If abnormal symptoms appear, administration should be stopped immediately and appropriate treatment sought. Regular monitoring is necessary as there may be an increase in liver function test results or renal function abnormalities. If any abnormal signs are detected, the medication should be discontinued and a doctor consulted. Anemia may be indicated in blood tests, making careful observation of symptoms important. Allergic symptoms such as skin rash or itching may also occasionally appear. This medication can affect the central nervous system, leading to insomnia, drowsiness, headaches, tingling in the limbs, and rigidity or tremors. If these symptoms occur, consultation with a physician is recommended. Gastrointestinal discomfort may arise, including nausea, vomiting, reduced appetite, abdominal pain, diarrhea, and constipation. In severe cases, abdominal bloating or stomatitis may occur. Urogenital symptoms may include difficulty urinating, incontinence, or a feeling of incomplete bladder emptying, so caution is advised. General symptoms such as weakness, dizziness, unsteadiness, and reduced muscle tension may also occur, so any changes should be reported immediately. Rarely, symptoms such as facial flushing, sweating, or swelling have been reported. This medication may rarely cause severe immune responses such as anaphylaxis or skin adverse reactions like angioedema. If symptoms such as fever, blisters, itching, eye redness, or stomatitis occur, administration should be stopped immediately. This medication has the potential to induce a serious skin condition called Stevens-Johnson syndrome, so any skin abnormalities should be reported to a doctor. If weakness, unsteadiness, or drowsiness occurs during treatment, the dosage should be reduced or the medication discontinued. As drowsiness or decreased concentration may occur, driving or operating dangerous machinery should be avoided. Caution should be exercised when this medication is taken with similar medications or other muscle relaxants, as coordination disturbances can occur with combined use. Women who are pregnant or may become pregnant should carefully consider the risks and benefits before taking this medication, and nursing mothers should ideally avoid taking it or cease nursing. Safety in children has not been sufficiently confirmed, so it should be used cautiously in pediatric patients. Elderly patients may have decreased body function, so caution is needed to adjust the dosage when using this medication.
