Relief of moderate to severe acute and chronic pain
This medicine is used to relieve moderate to severe acute and chronic pain.
Children over 12 and adults: The dosage should be adjusted according to the patient's level of pain and response to treatment. An initial dose of 2 tablets is recommended, thereafter maintaining a minimum interval of 6 hours between doses, ensuring that no more than 8 tablets are taken in one day. The lowest effective dose should be administered for the shortest duration possible. Avoid taking this medication for longer than necessary, and if prolonged treatment is required due to the nature of the disease and severity, regular monitoring should be conducted to reassess the necessity of ongoing treatment. Elderly Administer the usual adult dosage. However, for elderly patients over 75, the half-life of tramadol is prolonged by 17% during oral administration, thus ensure at least 6 hours between doses. Renal impairment For patients with moderate renal impairment (creatinine clearance of 10-30 mL/min), extend the interval to 12 hours. It is not recommended for those with severe renal impairment (creatinine clearance less than 10 mL/min). Tramadal is removed very slowly during hemodialysis and filtration, so there is no need for re-administration after dialysis to maintain its effect. Liver impairment For moderate liver impairment, consider carefully extending the dosing interval.
Applicable for children over 12 years and adults; no separate pediatric dosage is specified.

Patients with severe asthma or respiratory issues may find it harder to breathe while taking this medication, and should only take it in an environment with medical personnel nearby or where emergency equipment is available.

Certain patients with rapid metabolism of this medication may experience stronger effects and side effects than expected, so dosage adjustments and symptom monitoring are necessary.

This medication may worsen respiratory problems such as sleep apnea, so related symptoms should be regularly monitored for any deterioration. Elderly patients or those at risk of hyponatremia must closely observe changes in serum sodium levels while taking this medication. Before taking this medication, it is essential to adhere to the recommended dosage and avoid using it concurrently with other analgesics. Sudden discontinuation can lead to withdrawal symptoms such as anxiety, insomnia, and tremors; thus, gradually reducing the dosage in consultation with medical personnel is recommended.
