Those who have a history of allergies to the medication or have poor liver function should use it with caution. While using this medication, allergic symptoms such as skin rash, itching, and difficulty breathing may occur, so if such symptoms appear, use should be stopped immediately and consultation with a physician should be sought. Rarely, severe skin conditions may occur, so if symptoms such as fever, skin rash, blisters, conjunctival injection, or oral inflammation appear, the use of the medication should be stopped immediately and a medical professional should be consulted. Due to possible effects on liver and kidney function, if adverse symptoms arise, administration should be stopped immediately, and appropriate medical treatment should be received. Caution should be exercised as side effects such as dizziness, drowsiness, headache, indigestion, nausea, constipation, and diarrhea may occur while taking this medication. If weakness, staggering, or drowsiness occurs during treatment, it may be necessary to reduce or stop the medication dosage. Because drowsiness and decreased concentration can occur, it is advisable to avoid driving or operating dangerous machinery while taking this medication. Women who are pregnant or may become pregnant should only take this medication if the benefits are deemed greater than the risks, and breastfeeding should be avoided if possible; if it must be taken, breastfeeding should be discontinued. The safety of this medication has not been sufficiently established in children, so caution is needed when using it, and elderly patients may require special attention, such as dosage adjustments due to decreased physical function.
