(Extended-Release Naltrexone Injection)

Vivitrol Program in Sacramento

Vivitrol is an injectable dose of extended-release, long-acting naltrexone that blocks incoming opioids. Vivitrol is administered once every four weeks to patients enrolled in this program.

Patients must be off all opioids for at least ten days prior to initiating Vivitrol. Patients must also be off methadone or buprenorphine for at least fourteen days prior to initiating Vivitrol. This medication does not remove withdrawal symptoms.

Vivitrol Program

Because Vivitrol is not an opioid agonist medication, it is different from methadone and buprenorphine. It does not stabilize active opioid withdrawal. Instead, it is used after the required opioid-free period to help block opioid effects and support relapse prevention.

The Vivitrol Program may be appropriate for patients who have completed withdrawal, are medically eligible, and want a monthly injection option that supports adherence without daily medication dosing.

Treatment includes medical evaluation, lab testing when needed, counseling support, drug testing, naloxone access, referrals, and discharge planning to support long-term recovery.

In summary, Vivitrol accomplishes the following main goals for the patient:

  1. 1.Blocks incoming opioids
  2. 2.May reduce drug cravings
  3. 3.Reduces alcohol cravings
  4. 4.Monthly injection-based adherence

Support recovery with monthly relapse-prevention care.

Frequently Asked Questions

At C.O.R.E., we strive to individualize treatment and maximize success. There is no time pressure. Some patients do well with short-term treatment while others benefit from long-term treatment. We know relapse is common and can have devastating consequences, so we continue treatment as long as necessary to help each patient achieve lasting success.

We work hard to educate patients about the benefits and safety of MAT. Many myths exist regarding methadone and other medications, but these concerns are discussed thoroughly with your treatment team. MAT is closely monitored, and when patients are ready, medications can be tapered safely under medical supervision to minimize withdrawal symptoms.

We work closely with each patient to achieve a "normalizing" medication dose that relieves withdrawal symptoms and cravings while minimizing side effects. Through collaboration between medical providers, counselors, and dispensing staff, most patients reach this goal within days or weeks.

Your first visit includes an intake assessment, medical history, physical examination, and counseling evaluation. Together we'll discuss treatment options and develop an individualized care plan. Medication doses are adjusted carefully based on your response, and regular communication with your care team is encouraged.

Not necessarily. C.O.R.E. Medical Clinic serves patients throughout Sacramento, West Sacramento, and surrounding communities. Many patients choose us because of our accessibility, treatment approach, and convenient location.

Opioid withdrawal is extremely uncomfortable and often leads to continued opioid use without treatment. While opioid withdrawal itself is usually not life-threatening, withdrawal involving alcohol, benzodiazepines, stimulants, or other substances can require coordinated medical care. Our treatment program helps minimize withdrawal symptoms through carefully monitored medication adjustments.

Most patients can continue working and maintaining their normal daily routines while beginning treatment. If residential or coordinated medical care is necessary, temporary time away from work may be recommended. Our clinic hours are designed to accommodate the schedules of working patients whenever possible.

C.O.R.E. Medical Clinic accepts several insurance plans, including Medi-Cal, MHN, Anthem, Medicare, Humana, Kaiser Permanente, Optum, Blue Shield of California, Magellan Health, and Western Health Advantage.
