There is no such thing as what medication is good for cancer pain. Due to individual variability, the use of medication needs to be considered in the context of one’s own situation. For cancer pain, patients can take non-steroidal analgesics, weak opioids, strong opioids, such as aspirin, codeine, morphine and so on. 1. Non-steroidal analgesics: If cancer patients have mild pain symptoms, they can take non-steroidal analgesics such as aspirin, acetaminophen, ibuprofen, celecoxib, indomethacin and so on orally under the guidance of doctors. After medication, the symptoms of pain can be relieved. 2. Weak opioids: For patients with moderate cancer pain, they can take weak opioids, such as codeine, lofenodrine, tramadol, etc., as prescribed by the doctor. 3. Strong opioids: If the above drugs cannot relieve the symptoms of pain, strong opioids, such as morphine and oxycodone hydrochloride, should be taken orally under the guidance of a doctor if necessary. It is recommended that cancer patients who suffer from pain should take medication under the guidance of a doctor.
