Understanding Xanax: Risks, Dosage, Detox and More | High Focus Centers

Xanax, also known by its generic name alprazolam, is a prescription medication used to treat anxiety and panic disorders. It belongs to a class of drugs called benzodiazepines, which work by slowing down the brain and nervous system to produce a calming effect. 

While Xanax can be effective when taken as prescribed, it’s also one of the most misused prescription drugs in the country. It’s important to be aware that misuse can lead to dependence, withdrawal symptoms, overdose and serious medical complications—especially when combined with other substances. Understanding these risks is crucial for making informed decisions about your health. 

This guide covers what Xanax is, how much is considered too much, what detox from Xanax looks like, how it shows up on drug tests and terms you might hear on the street. It also explains a little-known side effect of Xanax withdrawal called “benzo belly.” 

How Much Xanax Is Too Much? 

When used for short-term relief from anxiety or panic, Xanax is typically prescribed in low doses: 0.25 mg to 0.5 mg, taken up to three times a day. The maximum recommended dose is 4 mg per day, although this may vary depending on the individual and the duration of treatment. 

Taking more than the prescribed dose—especially without medical supervision—is considered too much. Some people misuse Xanax by taking higher doses to feel calm and euphoric or to help them sleep. However, high doses can cause: 

• Confusion 

• Slurred speech 

• Loss of coordination 

• Difficulty breathing 

• Memory loss 

• Loss of consciousness 

Large doses also increase the risk of overdose, especially when Xanax is combined with other depressants like alcohol or opioids. 

How Many Milligrams Are in a Xanax Bar? 

A Xanax bar typically refers to a rectangular 2 mg tablet of alprazolam. These bars are designed to be scored, allowing them to be split into smaller doses. For example: 

• Breaking a bar in half gives you two 1 mg doses. 

• Breaking it into quarters gives you four 0.5 mg doses. 

While 2 mg is a high dose, it’s still within the medical dosing guidelines for people who have developed a tolerance under a doctor’s care. However, on the street, these bars are often misused, and counterfeit versions containing fentanyl or other substances are common. 

Does Xanax Come in Different Colors? 

Yes, Xanax is manufactured in a variety of colors, shapes, and dosages. These differences usually depend on the manufacturer and dosage strength. Here are the most common: 

• White: Often used for 0.25 mg or 2 mg tablets. 

• Blue: Usually 1 mg. 

• Pink or peach: Typically 0.5 mg. 

• Yellow: Commonly 2 mg; sometimes called “school buses.” 

• Green: Also 2 mg; sometimes referred to as “Hulks.” 

It’s important to note that color alone does not indicate strength—always check the imprint code on the pill to confirm its contents. 

What Are the Street Names for Xanax? 

If someone is using Xanax without a prescription, they may refer to it by a slang or street name. Common terms include: 

• Bars 

• Zannies or Xannies 

• Totem poles 

• Handlebars 

• Blue footballs (for 1 mg blue tablets) 

• School buses (for yellow 2 mg bars) 

Knowing these terms can help caregivers, parents, or loved ones recognize signs of misuse. By being proactive and informed, you can take steps to address the issue and support your loved ones in their recovery journey. 

Does Xanax Show Up on a Drug Test? 

Yes, Xanax is detectable on most standard drug screens under the benzodiazepine category. Detection times depend on the type of test and how frequently the person has used the drug: 

• Urine test: Detectable for up to 6 weeks with heavy use or 4–7 days with light use. 

• Blood test: Detectable for 1–5 days. 

• Saliva test: Detectable for up to 2.5 days. 

• Hair test: Can detect use for up to 90 days. 

If you are prescribed Xanax and are scheduled for a drug test, it’s important to disclose your prescription beforehand. This is because Xanax can show up on drug tests, and without this information, the results may be misinterpreted. By disclosing your prescription, you can ensure that the results are accurately interpreted and avoid any unnecessary concerns or consequences. 

Why Is Xanax Detox So Dangerous? 

Detoxing from Xanax can be dangerous and even life-threatening, especially if a person stops using it suddenly after long-term or high-dose use. This is because the body becomes dependent on the drug to function normally. 

Withdrawal symptoms may include: 

• Severe anxiety and panic attacks 

• Insomnia 

• Sweating 

• Tremors 

• Seizures 

• Hallucinations 

• Rapid heart rate 

• Muscle pain 

Xanax withdrawal can begin within hours of the last dose, and symptoms may peak within 1–4 days. A medically supervised detox is the safest way to manage withdrawal and reduce the risk of seizures and other complications. 

What Happens When You Mix Xanax With Other Substances? 

Mixing Xanax with other drugs can be extremely risky. It increases the depressant effect on the central nervous system, which controls breathing, heart rate, and brain function. 

Common substances people mix with Xanax include: 

• Alcohol: Can cause blackouts, vomiting, slowed breathing, and even death. 

• Opioids (like heroin, oxycodone, or fentanyl) Significantly raise the risk of overdose. 

• Other benzodiazepines or sleeping pills May lead to coma or unresponsiveness. 

• Marijuana: Can intensify confusion, fatigue, and mental fog. 

Even when taken in seemingly small amounts, the combination of Xanax and another substance can be fatal. 

What Is “Benzo Belly”? 

“Benzo belly” is a term used to describe the gastrointestinal discomfort that often occurs during or after benzodiazepine withdrawal. It’s one of the most persistent and frustrating withdrawal symptoms. 

Common symptoms include: 

• Bloating or fullness 

• Nausea or stomach cramps 

• Loss of appetite 

• Gas or indigestion 

• Diarrhea or constipation 

Why Does Benzo Belly Happen? 

When someone stops using benzodiazepines, their nervous system becomes overactive. Because the digestive system is closely tied to the nervous system, withdrawal often disrupts normal gut function. 

How Long Does It Last? 

For some people, benzo belly lasts a few weeks. For others, especially those tapering off long-term use, it can persist for several months. Eating small, bland meals, staying hydrated, and managing stress can help ease symptoms. Medical support during detox is key to managing this and other withdrawal effects. 

When to Seek Help 

If you or someone you care about is using Xanax more frequently, taking higher doses, or combining it with other substances, it may be time to seek support. Stopping Xanax without medical supervision can be dangerous, but remember, you don’t have to go through it alone. Professional help is crucial for a safe and successful recovery.
