What's the difference between Valium and Xanax?
Valium and Xanax are brand names for two types of medication for anxiety. The generic name for Valium is diazepam. The generic name for Xanax is alprazolam.
Many anxiety symptoms result, to some extent, from a chemical imbalance in the brain. Medication can help change this imbalance.
Sedatives slow down certain functions in the body. This can help a person sleep or make them feel calmer.
The best choice of medication and the dosage and duration of treatment will be different for each individual.

Valium and Xanax are different medications. A doctor should help a person decide which is most suitable.
People can take either medication as tablets or liquid, but adults usually only receive a prescription for pills.
An individual tends to take Valium or Xanax one to four times per day, but the dosage will depend on the person's needs and on the medication, due to the differing lengths of action.
The following are some key facts about each:
|used to treat severe anxiety and panic disorders||used to treat less severe anxiety disorders, alcohol and drug withdrawal, muscle spasms, and seizures|
|intermediate onset (15–30 minutes)||rapid onset (within 15 minutes)|
|can cause dependency||can cause dependency|
|causes withdrawal symptoms||causes withdrawal symptoms|
|withdrawal does not last longer if a person takes the drug for a longer period||withdrawal does not last longer if a person takes the drug for a longer period|
How they work
Both medications work with a chemical in the brain called gamma-Aminobutyric acid (GABA).
GABA reduces activity in parts of the brain that control memory, emotions, logical thought, and functions such as breathing.
Valium and Xanax increase the effects of GABA. This makes the muscles relax, reduces anxiety, and causes drowsiness.

A person who has taken Valium or Xanax regularly for a long time may experience withdrawal if they stop taking it. These symptoms may be physical or mental.
Withdrawal symptoms are similar for both, but Xanax may cause more symptoms than Valium.
Some examples of these withdrawal symptoms include:
- stomach cramps
- increased feeling of anxiety
- problems sleeping
A person should seek medical advice if they plan to stop taking either medication. A doctor will usually reduce the amount gradually to lessen the withdrawal symptoms.
It is possible for withdrawal symptoms to last for weeks or months. Receiving support from friends, family, a group, or an organization can help when coping with these effects. A doctor may be able to prescribe medication to help with withdrawal symptoms.
If a person does not have certain underlying health conditions, Valium and Xanax are safe to take as a doctor instructs.
Both medications can cause dependency because they trigger significant changes in the brain, and withdrawal can be difficult.
For this reason, doctors tend to recommend Valium and Xanax for short-term use.
People may not be able to take certain medications alongside Valium or Xanax. A person should talk with their doctor or pharmacist and review current medications to decide what they can or cannot take.
