Brixadi is used to treat moderate to severe opioid use disorders.1 Being administered in a clinical setting makes adherence to the treatment plan easy, provides steady withdrawal symptom relief, and has minimal risk of abuse. Whether you want to switch buprenorphine medication or initiate treatment, here is everything you need to know about Brixadi dosing.

Can’t remember to take your buccal buprenorphine doses daily? Brixadi (Injectable Buprenorphine) is available at ChoicePoint. Call 844.445.2565 to learn when you can start treatment and if you’re ready for it.

 

 

Highlights

  1. Brixadi is used in place of single-dose buprenorphine transmucosal products to achieve stability.
  2. Brixadi is a medication with prolonged release. Over an extended period, it is gradually released into your body. 
  3. It is taken in weekly and monthly doses to reduce opioid withdrawal symptoms, minimizing chances of relapse and cravings.
  4. To start your Brixadi treatment promptly, consulting a same-day rehab in NJ is the safest choice.

 

Brixadi Dosing Schedule 

Before beginning Brixadi dosing, you must first take a test dose of generic buprenorphine as a sublingual tablet. If you are not currently taking buprenorphine. This enables your physician to modify your Brixadi regimen as necessary to effectively handle any withdrawal symptoms. During the first week of treatment, your doctor will gradually raise the dosage of Brixadi.

Before digging deeper into the Brixadi dosing schedule, here is a precise Brixadi dosing chart:

Weekly dose Monthly dose
16 mg 64 mg
24 mg 96 mg
32 mg 128 mg

Brixadi Dose When You Take It For the First Time

For individuals who are not currently undergoing buprenorphine treatment, the suggested weekly dose is 24 mg of Brixadi, which should be titrated up throughout the first week of treatment as follows2:

  1. Mild to moderate withdrawal: A test dose of 4 mg of transmucosal buprenorphine to prevent triggering an opioid withdrawal syndrome.
  2. 1st Dose: Brixadi 16 mg, if the transmucosal buprenorphine dose is tolerated without causing an abrupt withdrawal.
  3. Weekly Dose: To reach the suggested 24 mg Brixadi maintenance dose, doctors give an extra 8 mg within 3 days following the initial dose.
  4. Extra Dose: Depending on the needs of the patient, an extra 8 mg of Brixadi during the first week of treatment, waiting at least 24 hours after the prior injection, for a total weekly dose of 32 mg. 
  5. Maximum Dose: 32 mg is the maximum weekly dose.

Based on the total weekly dose determined following the first week, practitioners administer further injections. 

People Who Have Been On Buprenorphine 

  1. Monthly Dose: If you have been taking a buprenorphine tablet at a steady dose for a while, you can be prescribed monthly injections of Brixadi. 
  2. Maintenance Dose: 96 mg per month is the typical maintenance dosage. 
  3. Maximum Dose: The maximum dosage is 128 mg per month.

How Long Does it Take for Brixadi to Start Working?

Brixadi takes effect right after getting the dose. As it releases buprenorphine slowly into the system, the buprenorphine levels peak 24 hours later.3 Due to the same reason, it has a lower chance of precipitated withdrawal.

Is Brixadi Better Than Sublocade?

Both Brixadi and Sublocade are successful in the OUD treatment, but they differ in doses and delivery. The doctors take your unique needs and preferences into account while deciding between them. For instance, Brixadi provides a greater range of dosages, enabling medical professionals to modify the dosage in accordance with patient requirements. Conversely, Sublocade only provides monthly injections and has two predetermined dosages.

3 Factors That Affect Brixadi Dosage

Your prescription Brixadi injection dosage may vary depending on a number of factors. Among them are:

  1. The nature of chronic opioid use 
  2. If there is a condition that makes Brixadi use dangerous
  3. Other drugs you may be taking

 

4 Tips for Taking Brixadi Doses Efficiently

  1. Mark the Dates: Scheduling the times of your consultations to discuss how your medication is progressing and ensuring that you don’t miss any Brixadi shot.
  2. Avoid Missing Doses: Missed doses have the potential to cause symptoms of opioid withdrawal, including diarrhea, cramping in the stomach, and muscle soreness.
  3. Don’t Squeeze Down the Bump: You may notice a lump at the injection site. This firm gel will gradually release the drug over time, and the lump disappears on its own. 
  4. Know About Brixadi Administration: The buttocks, thighs, stomach, and upper arms are among the body parts that are Brixadi injection sites. These sites are selected and rotated by the provider after discussing with the patient.4

 

 

7 Risks and Warnings for Brixadi Dosing

If you plan to take a Brixadi shot, give attention to these factors: 

  1. Pregnancy: Long-term exposure to Brixadi doses may cause Neonatal withdrawal syndrome in newborns.5
  2. Be Careful If You Have Experienced Head Trauma: Buprenorphine may increase the pressure of fluids inside your brain. Notify your doctor immediately if you have a head injury while taking Brixadi.
  3. Decline in Adrenal Hormone Levels: Taking Brixadi for over a month may lead to lethargy, nausea, dizziness, and weakness due to a drop in hormonal levels. However, it is uncommon
  4. Risk of Withdrawal: Quitting all of a sudden may cause opioid withdrawal symptoms.
  5. Dangerous for Existing Liver Impairment: People who have hepatic impairment are usually not suitable candidates for Brixadi.6
  6. Not for People Without a History of Opioid Use: If you aren’t on opioids, the healthcare provider won’t generally prescribe Brixadi.
  7. Slow Breathing: One of the most risky Brixadi side effects is respiratory depression, which can happen at doses given by the doctor.

Importance of Clinical Supervision For Brixadi Dosing

Throughout the recovery procedure, periodic assessment from a doctor is compulsory due to the reasons stated below:

1. Treatment Evaluation

When taking Brixadi, the condition of the patient has to be evaluated continuously with each dose, depending on the severity of OUD.

2. Examination of the Brixadi Injection Site

The medical practitioner looks for infection or signs of tampering on the depot released from a shot.

3. Discontinuation of Brixadi Injection

When the patient decides to quit Brixadi, the signs of withdrawal have to be monitored by the doctors to avoid complications. Due to a lengthy half-life, Brixadi withdrawal symptoms may appear two to five months after the last injection.
