Taking painkillers after surgery depends on the type of surgery the patient had, and the severity of the condition. If it is just the removal of a body mass, you can usually use ibuprofen extended-release capsules or depot tablets for pain relief, which are more effective. If the patient is undergoing a larger surgery, then tramadol hydrochloride tablets, aminoglutethimide tablets, or morphine hydrochloride tablets can be used for treatment, which has a better analgesic effect. If the pain is persistent and traumatic, the patient can be treated with an analgesic pump by the attending physician for continuous pain relief, which is also more effective. If the pain is caused by intestinal spasm, antispasmodic drugs can be given to relieve pain, such as mebendazole injection and 654-2. Therefore, the medication used varies from patient to patient, so you can consult with the attending physician, and generally patients should not self-medicate.
