Medication for back and nerve painNSAIDs (NonSteroidal Anti-Inflammatory Drugs): There is good evidence of benefit in the short term from NSAIDs for the treatment of back pain and nerve pain. There are several different types drugs within this category and some patients may respond differently depending upon which drug suits them best in terms of pain control and side effects. There are also some risks associated with long term use.
Analgesics: Simple analgesics in the form of paracetamol have not been shown to be helpful in controlled clinical trials.
Neuropathic pain medication: Amitryptiline, gabapentin and pregabalin may be of benefit in radiating nerve pain (pain that spreads down the arm or leg). They do not seem to be helpful for back pain.
Weak opiates: Weak opiates such as codeine may be combined with simple paracetamol and some trials suggest that there could be benefit.
Strong opiates: These should only be used under medical supervision as the risk of harm is high (mostly risks of addiction and from side-effects).
Diazepam: This is sometimes used for muscle spasm in acute low back pain. There are no quality clinical trials to support this use. The risk of harm is considered high.
