Men and women who are physically reliant to drugs or alcohol and want help will initially go through detoxification before receiving other treatment services in drug rehab. Detoxification is basically the procedure of the drug being eradicated from one's system, which is usually uncomfortable and may hold risks if not conducted in a setting which can provide appropriate support and medical intervention as necessary. Detox services are offered at either a professional drug or alcohol detoxification facility or a drug rehab facility which can adequately oversee and supply medical supervision for men and women who are just coming off of drugs. Detoxification services typically include insuring the client is as comfortable as possible while detoxing and going through drug or alcohol withdrawal, offering proper nutrition and ensuring the person is receiving proper rest, and supplying supplements and medicine as necessary to make the detox process as easy and safe as possible. The person in detox will sometimes be encouraged to take part in some sort of physical activity such as walking, yoga, etc. At a drug detox facility or drug treatment facility which can offer detox services, the client will have detoxification staff at their disposal around the clock to make certain that any complications are fixed as swiftly and safely as possible.
