This medication should not be used in patients with an allergic reaction to it or in patients with myasthenia gravis. Patients with a history of drug hypersensitivity or liver dysfunction should use this medication with caution, as there is a risk of worsening liver function. Rarely, during the use of this medication, severe allergic reactions or serious skin abnormalities may occur, so if symptoms such as rash, itching, hives, swelling, difficulty breathing, fever, blisters, conjunctival injection, or stomatitis appear, the medication should be stopped immediately and medical attention sought. Liver or kidney dysfunction may occur, so if symptoms appear, they should be reported immediately, as blood abnormalities, symptoms of central nervous system disturbances (insomnia, drowsiness, headache, etc.), digestive symptoms (nausea, vomiting, diarrhea, etc.), and urinary issues (urinary retention, feeling of incomplete voiding) may arise. Dizziness or drowsiness may occur while taking this medication, so it is advisable to avoid dangerous activities such as driving or operating machinery. Women who are pregnant or may become pregnant should only take this medication if the benefits of treatment are judged to outweigh the risks, and nursing mothers should, if possible, avoid taking this medication and should discontinue nursing in unavoidable cases. Safety in children has not been fully established, so it should be used with caution in children.
