Can Xanax Lower Your Blood Pressure?

Furthermore can Valium lower your blood pressure too?

Technically yes but... we'll talk more about that.

How Does Xanax and Valium Lower BP?

Pills in a bottle

Xanax (alprazolam) and Valium (diazepam) are both benzodiazepine medications that belong to a class of drugs known for their anxiolytic, sedative, and anticonvulsant properties. They are primarily prescribed for the management of anxiety, panic disorders, and certain seizure disorders. In addition, they are sometimes used as muscle relaxants, preoperative sedatives, and adjunctive treatments for alcohol withdrawal symptoms. Both medications function by enhancing the activity of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the central nervous system, which leads to a calming effect.

Xanax and Valium, while not specifically indicated for the treatment of high blood pressure, may have an indirect impact on blood pressure regulation due to their anxiolytic effects. Anxiety and stress can lead to acute elevations in blood pressure as a result of increased sympathetic nervous system activity. This heightened activity can cause vasoconstriction, an increase in heart rate, and a subsequent rise in blood pressure. When Xanax or Valium is administered to alleviate anxiety, the resulting anxiolytic effects may help to reduce acute spikes in blood pressure associated with anxiety.

However, it is crucial to emphasize that neither Xanax nor Valium is a first-line treatment for hypertension. Their effects on blood pressure are not well-documented in long-term use, and they are not designed to directly target the mechanisms responsible for blood pressure regulation.

Benzodiazepine Abuse

Benzodiazepines like Xanax and Valium have the potential for dependence, addiction, and withdrawal symptoms, particularly when used for extended periods or at high doses. 

Benzodiazepines, such as Xanax (alprazolam) and Valium (diazepam), have a high risk of abuse due to several factors, which include their rapid onset of action, the euphoria or relaxation they produce, and their potential for tolerance and dependence.

  • Rapid onset of action: Benzodiazepines are known for their quick and potent effects, which can be felt within minutes to hours after administration. This rapid onset of action can be appealing to individuals seeking immediate relief from anxiety, stress, or other unpleasant symptoms. The fast-acting nature of benzodiazepines can contribute to their reinforcing properties and increase the likelihood of repeated use and abuse.

  • Euphoria and relaxation: Benzodiazepines act on the central nervous system by enhancing the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), which results in a calming effect. This can lead to feelings of relaxation, sedation, and in some cases, euphoria. These pleasurable effects may encourage individuals to misuse benzodiazepines for non-medical reasons, increasing the risk of abuse.

  • Tolerance: With prolonged use of benzodiazepines, the body can become accustomed to their presence, leading to a decrease in their effectiveness. This is known as tolerance. When tolerance develops, individuals may require higher doses of the medication to achieve the same therapeutic effect, which can increase the risk of abuse and adverse effects.

  • Dependence: Both physical and psychological dependence can develop with benzodiazepine use. Physical dependence occurs when the body adapts to the presence of the drug and requires it to function normally. Discontinuation or a reduction in dosage can lead to withdrawal symptoms, such as anxiety, irritability, insomnia, and, in severe cases, seizures. Psychological dependence occurs when individuals feel compelled to use the drug to cope with stress, anxiety, or other emotional states. The development of dependence can increase the likelihood of abuse as individuals may continue to take the drug to avoid withdrawal symptoms or to maintain the desired psychological state.

  • Prescription availability: Since benzodiazepines are often prescribed for legitimate medical conditions, such as anxiety disorders, they are widely available. This accessibility can contribute to their misuse and abuse, as individuals may take higher doses than prescribed or use them without a prescription.

  • Polydrug use: Benzodiazepines are sometimes misused in combination with other substances, such as opioids or alcohol, to enhance their effects or to counteract the side effects of other drugs. This polydrug use can increase the risk of abuse, as well as the likelihood of dangerous interactions and adverse effects.


Due to these factors, benzodiazepines have a high risk of abuse, and it is essential to use them responsibly and under the guidance of a healthcare professional. They should be prescribed for the shortest possible duration and at the lowest effective dose to minimize the potential for abuse, tolerance, and dependence. As such, there's no reason one should be taking Xanax specifically for Blood Pressure reduction. This would be off-label, and potentially disastrously harmful.
