This medication should not be used in certain patients. First, patients who have had an allergic reaction to this drug or those with myasthenia gravis should not be administered the drug. Also, it should be administered with caution in patients with a history of drug hypersensitivity or with liver dysfunction. Caution is needed because liver function may deteriorate. During the use of this drug, severe allergic reactions such as shock or anaphylaxis may rarely occur, so if symptoms such as skin redness, itching, hives, swelling, or difficulty breathing appear, administration should be immediately discontinued and appropriate treatment should be sought. Additionally, serious skin conditions such as toxic epidermal necrolysis (Lyell's syndrome) or Stevens-Johnson syndrome may occur, so administration should be stopped if symptoms such as fever, erythema, blisters, itching, eye redness, or stomatitis appear. Moreover, various side effects such as liver dysfunction, renal dysfunction, anemia, skin rash, itching, insomnia, drowsiness, headache, dyspepsia, nausea, vomiting, constipation, diarrhea, abdominal pain, urinary retention, urinary incontinence, weakness, dizziness, etc. have been reported, so it is necessary to consult a healthcare professional if symptoms occur. While taking this medication, symptoms such as weakness, staggering, and drowsiness may appear, so it may be necessary to reduce the dosage or discontinue use if these symptoms occur. Additionally, drowsiness or decreased alertness may occur, so it is advisable to avoid driving or operating dangerous machinery. Caution should be exercised when taking this drug in conjunction with similar medications like tolperisone hydrochloride or methocarbamol as visual disturbances may occur. Women who are pregnant or may become pregnant should only use this drug when the benefits of treatment outweigh the risks, as safety has not been established. If breastfeeding, it is advisable to avoid administration. If absolutely necessary, breastfeeding should be stopped. The safety in children has not been sufficiently confirmed, so care should be taken with its use. Elderly individuals may have decreased physical function; therefore, careful administration is required, including adjusting the dose.
