What Is an R039 Yellow Xanax Bar?
The R039 yellow Xanax bar is one of the most commonly counterfeited benzodiazepine tablets on the street. Genuine R039 bars contain 2 mg of alprazolam (Xanax), manufactured by Actavis Pharma. They are bright yellow, rectangular pills with “R039” imprinted on one side and scored on the other for tablet splitting. However, many R039 pills sold illicitly are counterfeit and may contain fentanyl, other opioids, or dangerously high doses of alprazolam.
If you or someone you love needs more than detox, Nova Recovery Center also provides alcohol rehab austin.
Nova Recovery Center’s addiction treatment program program provides medically supervised, evidence-based care.
Benzodiazepines like Xanax are legitimate prescription medications for anxiety and panic disorders, but their misuse—especially counterfeit versions—carries severe health and addiction risks.
Risks of R039 Yellow Xanax Bars
Beyond the prescription use for anxiety, R039 bars pose multiple dangers:
- Counterfeit & contaminated pills: Street R039 bars frequently contain fentanyl, heroin, or other illicit substances that dramatically increase overdose risk.
- Rapid physical dependence: Even legitimate Xanax is highly addictive when misused. Daily use can create dependence in as little as 2 weeks.
- Overdose & respiratory depression: Benzodiazepines slow the central nervous system. When combined with alcohol or opioids, they can cause fatal respiratory failure.
- Cognitive impairment: Regular Xanax use impairs memory, judgment, and coordination—increasing accident risk.
- Severe withdrawal: Abrupt cessation after heavy use can trigger dangerous withdrawal symptoms, including seizures, requiring medical supervision.
- Tolerance buildup: Over time, users need higher doses to feel the same effect, driving addiction escalation.
How to Identify a Genuine R039 Yellow Xanax Bar
If you’ve received a prescription for alprazolam, knowing what a genuine pill looks like helps protect you:
- Color: Bright, uniform yellow (not pale or greenish).
- Imprint: “R039” clearly pressed on one side.
- Scoring: Three dividing lines on the reverse, creating four breakable segments.
- Shape: Rectangular / oblong.
- Texture: Smooth, not gritty or chalky.
- Source: Only from a licensed pharmacy with a valid prescription.
If a pill looks, feels, or tastes unusual—or you obtained it without a prescription—do not take it. Counterfeit pills are increasingly sophisticated and dangerous.
Benzodiazepine Addiction: Signs & How It Develops
Xanax addiction doesn’t always start intentionally. Many people begin with a legitimate prescription and gradually develop dependence. Others use R039 bars recreationally and quickly spiral into addiction.
Common Signs of Benzodiazepine Addiction
- Taking higher doses than prescribed or more frequently.
- Seeking multiple doctors or pharmacies (“doctor shopping”) to obtain more pills.
- Using illicit sources (street dealers) when prescriptions run out.
- Continuing use despite negative consequences (job loss, relationship damage, legal issues).
- Tolerance: needing larger doses to feel the same calming effect.
- Physical dependence: experiencing anxiety, tremors, or sleep disturbance when trying to stop.
- Neglecting responsibilities or hobbies due to Xanax use.
- Combining benzodiazepines with alcohol or opioids (a lethal combination).
Why Benzodiazepine Withdrawal Requires Medical Help
Unlike some other drug addictions, stopping benzodiazepines abruptly can be medically dangerous. Withdrawal symptoms include:
- Severe anxiety and panic attacks
- Insomnia and nightmares
- Tremors and muscle aches
- Seizures (potentially life-threatening)
- Hallucinations and confusion
- Rapid heart rate and sweating
At Nova Recovery Center, our medically supervised detox programs manage benzodiazepine withdrawal safely. We use a slow tapering protocol, sometimes substituting longer-acting benzodiazepines, combined with counseling and support to prevent relapse.

FAQ: R039 Yellow Xanax Bars & Benzodiazepine Addiction
Is R039 a real Xanax?
R039 is the imprint on genuine 2 mg alprazolam (Xanax) tablets manufactured by Actavis Pharma. However, many pills sold on the street with this imprint are counterfeit and may contain fentanyl, other drugs, or incorrect doses. Only obtain Xanax from a licensed pharmacy with a valid prescription.
Can you overdose on R039 yellow Xanax bars?
Yes. Benzodiazepines suppress the central nervous system and can cause respiratory depression, especially at high doses or when combined with alcohol or opioids. Counterfeit R039 bars containing fentanyl significantly increase overdose risk and can be fatal. If you suspect an overdose, call 911 immediately.
How long does it take to become addicted to Xanax?
Physical dependence can develop in as little as 2–4 weeks of daily use, even at prescribed doses. Psychological addiction may develop faster, especially if you use Xanax to self-medicate anxiety or trauma. Long-term misuse strengthens addiction and makes quitting harder.
Can you stop taking Xanax cold turkey?
No—stopping abruptly is dangerous and can cause seizures. Benzodiazepine withdrawal must be medically supervised. A doctor will typically taper your dose gradually over weeks or months while monitoring your symptoms and preventing relapse.
What is the best treatment for Xanax addiction?
The most effective approach combines medical detox, therapy (especially CBT), and ongoing counseling. Many people benefit from inpatient rehab for structured support, while others succeed with intensive outpatient programs. Nova Recovery Center offers both options and can help you choose the right level of care.
How long is benzodiazepine addiction treatment?
Treatment timelines vary. Detox typically takes 5–14 days, depending on your dose and dependence severity. Inpatient rehab programs usually last 28–90 days. Outpatient programs range from weeks to months. Most people benefit from ongoing therapy and support groups to maintain long-term sobriety.
