Paracetamol has antipyretic and analgesic properties and can be used to treat symptoms such as headache, migraine, joint pain, toothache, muscle pain, dysmenorrhea, and neuralgia. It can also be used to manage fever caused by the common cold. The drug usually takes effect within approximately 30 to 40 minutes after administration. If a patient metabolizes and excretes the drug quickly, the pain-relieving effect may last about 3 hours. However, in some patients with slower excretion of the drug, the effect may last up to 6 hours. Due to individual differences in physical condition, the duration of effect may vary.
When using this medication, caution is needed in patients who are allergic to its components or those with severe liver dysfunction. Possible adverse reactions include nausea, vomiting, pale skin, abdominal pain, and sweating. Always follow medical instructions when taking the medication and avoid increasing the dosage without authorization to prevent serious side effects.
