What drug does thalidomide belong to? Is it biopharmaceuticals? Are there any analgesic ingredients? Are there any side effects? Is it okay to take it for a long time?

Thalidomide, as a chemical drug, has a piperidine ring structure that induces sleep, so it has a sedative effect and does not contain analgesic components. Among the side effects, fetal malformation is the most serious, and there are many side effects. If you want to take it for a long time, it depends on whether it is symptomatic. If you can use something else, that's best.
