Xanax (Complete guide)


In this blog, we will discuss how Xanax is used, what disorders it treats, common side effects, and important precautions regarding usage. 


Xanax is a medication used to treat anxiety and panic disorders. Xanax is commonly prescribed to patients who have been diagnosed with a severe anxiety disorder, including panic disorder. It can also be prescribed to patients who have anxiety caused by depression as well as seizure disorders. 

Anxiety disorders can be diagnosed by a physician, usually a psychiatrist. Common symptoms of anxiety disorders include hypervigilance, irritability, restlessness, fear of impending doom, nausea, trembling, and more. For support and insight on anxiety disorders, click here.

How does Xanax work? 

Xanax works by activating receptors for the neurotransmitter gamma-aminobutyric acid (GABA) in the brain. GABA is the main inhibitory neurotransmitter in the brain, which means that it reduces the firing of neurons. When receptors for GABA are activated by Xanax, neurons are “quieter” and thus elicit a calming and sedative effect in the patient. 

Xanax is usually taken as needed, such as when the patient feels a panic attack coming on. It should not be used as a recreational drug or in combination with alcohol. 

What are some things I should know about taking Xanax? 

Xanax can be used for short-term relief of anxiety. It is available in short-acting or long-acting tablets, oral solution, or orally dissolving tablets. 

The extended-release form of Xanax is released slowly into the bloodstream and is only used to treat patients with panic disorder. 

In addition, Xanax can be taken as needed and supplemented with more long-term treatment for anxiety, such as a selective serotonin reuptake inhibitor (SSRI).  

Additional note: If you are a woman who is breastfeeding you should not breastfeed your baby while taking Xanax. 

What are the risks associated with taking Xanax? 

Xanax has addictive potential. The risk of addiction may be enhanced if you have a preexisting substance use disorder such as opioid or alcohol use disorder. In addition, people diagnosed with borderline personality disorder are more likely to use Xanax recreationally. Xanax and other benzodiazepine use account for 35% of drug-related hospital and emergency care visits. Men and women are equally as likely to use Xanax or other benzodiazepines recreationally. 

It is imperative to take this medication exactly as prescribed by your doctor in order to prevent the possibility of developing an addiction. 

What are the side effects of Xanax? 

During the first few hours after taking Xanax, you may experience dizziness or drowsiness. Do not drive or operate heavy machinery until you know how this drug affects you. 

Taking Xanax may cause a number of side effects including drowsiness, dizziness, and changes in sex drive. 

Other common side effects include:

• Trouble concentrating

• Sleep disturbances

• Muscle weakness

• Gastrointestinal problems (i.e., upset stomach, nausea, vomiting, or diarrhoea)

• Increased sweating

• Dry mouth

• Stuffy nose

• Changes in weight 

• Changes in appetite

These side effects usually go away within a few days to a few weeks. If they become more severe or do not go away, talk to your doctor. 

More serious side effects include changes in mood (hallucination, suicidal ideation), slurred speech, little or no urination, loss of coordination and balance, and memory problems. In rare cases, heart problems such as chest pain and abnormal heartbeat may occur. In addition, yellowing eyes and skin are rare but can occur. This yellowing of the eyes and skin is known as jaundice and indicates a serious liver problem. If you notice any of these problems, consult your doctor as soon as possible. 

If you are between the ages of 18 and 60 and have no other medical conditions, common side effects include low blood pressure, dizziness on standing, and heart palpitations. 

You may also experience the following: 

• Upset stomach (i.e., nausea, constipation)

• Dry mouth

• Headache

• Impaired reaction time

Are there any interactions between Xanax and other drugs?

Some drugs that are known to interact with Xanax are kava and sodium oxybate. Certain medications affect how your body metabolizes Xanax, including antidepressants such as fluoxetine and fluvoxamine. Some antifungals (itraconazole and ketoconazole) can increase drowsiness when taken with Xanax. 

The risks of serious side effects from Xanax are increased if taken with other drugs that cause drowsiness. These include opioids such as codeine or hydrocodone as well as alcohol, marijuana, other drugs for sleep and anxiety, muscle relaxants, or antihistamines. 

If you are taking other medications and have questions about whether or not they will interact with Xanax, consult your doctor immediately.

How do I know if I should take Xanax? 

Be sure not to confuse normal everyday anxiety with an anxiety disorder. If you are experiencing a problem at work, a big exam coming up, or an important decision, you are probably having a normal anxious reaction to life stressors. Anxiety disorders, however, are chronic and usually centre around irrational fears and worry. 

There are many different types of anxiety disorders such as generalized anxiety disorder (GAD), panic disorder, and social anxiety disorder, to name a few.   

Symptoms of GAD usually include: 

·      Feelings of restlessness or on edge

·      Difficulty concentrating and racing thoughts

·      Muscle tension

·      Irritability

·      Trouble sleeping

·      Difficulty controlling feelings of worry

·      Easily fatigued 

Xanax is commonly prescribed to people suffering from panic disorder because the calming effects help subside panic attacks. Symptoms of panic attacks include:

·      Heart palpitations or accelerated heart rate 

·      Sweating, trembling, shaking

·      Shortness of breath 

·      Feelings of impending doom 

Phobia-related disorders are another set of anxiety disorders that are characterized by an intense fear or aversion to specific situations or objects. This fear is usually out of proportion to the actual danger imposed by the situation or object.

Symptoms of phobia-related disorders include: 

·      Irrational or excessive worry about encountering the feared object or situation 

·      Intentional avoidance of feared object or situation 

·      Intense and immediate anxiety upon exposure to the object or situation 

Specific phobias can be related to situations such as flying or heights, or related to animals such as spiders. Some people also have phobias of receiving injections or blood.

Agoraphobia is another type of anxiety disorder where people have an intense fear of two or more of the following situations: 

·      Being in open or enclosed spaces

·      Standing in lines

·      Crowded areas

·      Using public transportation

·      Being outside of their home 

People with agoraphobia often avoid these situations out of fear that they will not be able to escape. Some have an intense fear that they will panic or have other embarrassing symptoms. In severe cases, people may avoid leaving their house altogether. 

If you suspect you have an anxiety disorder, do NOT start taking Xanax from a non-reputable source such as a friend, consult a psychiatrist immediately. 

Xanax should be taken in combination with the right kind of psychotherapy, such as talk therapy or cognitive-behavioural therapy (CBT). 

These therapies teach the patient active coping mechanisms to manage anxiety symptoms.

What happens if I suddenly stop taking Xanax?

If you stop taking this medication “cold-turkey”, you may experience severe withdrawal effects, including seizures. To prevent this, talk to your doctor about slowly tapering off Xanax. 

Even if you think you don’t need Xanax anymore, it is still necessary to consult with your doctor to come up with a treatment plan that is better for you. 

Is it possible to overdose on Xanax?

Yes, it is possible. An overdose on Xanax causes severe central nervous system (CNS) depression and may include one or more of the following symptoms: 

·      Coma

·      Fainting

·      Hypotension (low blood pressure) and hypoventilation (shallow breathing)

·      Impaired motor functions (I.e., dizziness, difficulty balancing, impaired or absence of reflexes, muscle weakness)

·      Drowsiness
