What is Opana ER?
Opana ER contains oxymorphone hydrochloride, a strong opioid analgesic that affects the central nervous system to reduce pain signals.
It was commonly prescribed for:
Severe chronic pain
Cancer-related pain
Post-surgical pain requiring long-term control
Serious injury recovery
Pain requiring extended opioid therapy
Unlike immediate-release pain medications, Opana ER was formulated for extended-release, meaning the medication worked gradually over time for longer-lasting pain control.
The FDA notes that Opana ER was first approved in 2006 for moderate-to-severe pain requiring continuous opioid treatment. In 2017, the FDA requested its removal from the market, and the manufacturer voluntarily withdrew it due to risks outweighing benefits.
How Opana ER Works
Opana ER works by binding to opioid receptors in the brain and spinal cord.
This helps:
Block pain messages
Reduce pain perception
Improve pain tolerance
Provide longer-lasting relief
Because it is an extended-release opioid, it was intended for scheduled pain control rather than quick, short-term pain relief.
It was not meant for “as needed” use for occasional pain.
Is Opana ER Still Available?
This is one of the most common questions.
Important Update
The brand-name Opana ER was voluntarily removed from the U.S. market in 2017 after the FDA requested withdrawal because the benefits no longer outweighed the risks, particularly concerns related to abuse and serious public health outcomes.
However:
Some generic oxymorphone extended-release products may still exist depending on pharmacy availability and prescribing practices.
Availability varies by location and healthcare provider decisions.
Patients should always speak directly with a licensed healthcare professional regarding current treatment options.
Common Side Effects
Like other opioid medications, Opana ER could cause side effects such as:
Drowsiness
Dizziness
Nausea
Vomiting
Constipation
Dry mouth
Sweating
Headache
Lightheadedness
These effects may be more noticeable when starting treatment or adjusting dosage.
Serious Side Effects
Some reactions require immediate medical attention:
Slow or difficult breathing
Severe confusion
Extreme drowsiness
Fainting
Low blood pressure
Chest pain
Allergic reactions
Loss of consciousness
These symptoms may indicate overdose or severe opioid complications.
Emergency medical care should be sought immediately.
Risk of Dependence and Addiction
Opana ER was classified as a Schedule II controlled substance, meaning it had a high potential for abuse and dependence.
Physical Dependence
Stopping suddenly after regular use could trigger withdrawal symptoms.
Psychological Dependence
Cravings and compulsive use may develop over time.
Tolerance
Patients may require higher doses for the same pain relief effect, increasing risk.
This is why strong opioids like oxymorphone require strict medical supervision.
Overdose Warning Signs
Opioid overdose is a medical emergency.
Symptoms may include:
Very slow breathing
Blue lips or fingertips
Pinpoint pupils
Extreme sleepiness
Unresponsiveness
Weak pulse
Pale or clammy skin
Emergency treatment with naloxone may help reverse overdose effects.
Immediate emergency care is critical.
Why Was Opana ER Withdrawn?
The FDA requested withdrawal after reviewing postmarketing safety data.
Concerns included:
Increased misuse through injection
Serious public health risks
Association with outbreaks of HIV and hepatitis C linked to abuse patterns
Risks outweighing long-term benefits
The FDA advisory committee voted that the risks were too high, leading to the voluntary withdrawal by the manufacturer in 2017.
This does not mean oxymorphone itself disappeared entirely—only the branded reformulated Opana ER product was withdrawn.
Safe Online Pharmacy Tips
People searching for Opana ER online should be extremely careful.
Use Licensed Pharmacies Only
Choose pharmacies that:
Require a valid prescription
Are licensed and regulated
Provide pharmacist access
Use secure payment systems
Avoid “No Prescription” Websites
These are often unsafe and may sell:
Counterfeit medications
Incorrect dosages
Dangerous substances
Confirm Medical Supervision
Strong opioids should only be used after a proper medical evaluation.
Protect Your Personal Information
Use secure checkout systems and verified websites.
Safety always comes first.
Legal Considerations
Because oxymorphone is a tightly controlled opioid, legal access requires:
A valid prescription
A licensed healthcare provider evaluation
Use of a legitimate pharmacy
Compliance with federal and state laws
Attempting to obtain controlled substances from unauthorized sources can be dangerous and illegal.
Patients should always follow medical and legal guidance.
Alternatives to Opana ER
Since brand-name Opana ER was withdrawn, healthcare providers may recommend alternatives depending on the pain condition.
Possible options include:
Other Prescription Pain Medications
Doctors may consider different opioid or non-opioid options depending on the patient’s needs.

Ibuprofen
Naproxen
Physical Therapy
Helpful for chronic pain, injury recovery, and musculoskeletal conditions.
Nerve Pain Treatments
For neuropathic pain conditions.
Topical Pain Relief

Responsible Use of Opioid Medications
Patients using strong pain medications should:
Follow exact dosage instructions
Never crush extended-release tablets
Avoid alcohol
Avoid mixing with sedatives unless approved
Attend regular medical follow-ups
Store medication securely
Dispose of unused medication safely
Responsible use greatly reduces the risk of serious complications.
Recognizing Opioid Misuse

Strong cravings
Early recognition allows faster treatment and better recovery outcomes.
Addiction is treatable with proper medical support.
