Opioid Use Disorder Treatment
Comprehensive and personalized treatment for opioid use disorder, combining medication with care for the whole person and continuity over the long term.

Overview
Opioid use disorder is a medical condition, and it is treated here as one. Tessy Kadavil is certified to provide buprenorphine therapy, and the practice offers comprehensive and personalized treatment for opioid use disorder using Sublocade® and Brixadi® — long-acting injections that can lessen cravings and withdrawal symptoms while supporting long-term recovery.
The approach goes beyond medication management. Contributing conditions — ADHD, anxiety, depression, trauma and other behavioral health concerns — are assessed and addressed as part of the same treatment, as are the physical and emotional effects associated with substance use. These are not side issues. They are frequently the reason a previous attempt at treatment did not last, and treating them is part of treating the disorder.
Through ongoing monitoring, supportive care and personalized treatment planning, the focus is on addressing the whole person and supporting recovery, improved health and long-term well-being.
There is no requirement to have already stopped, no requirement to arrive with a plan, and no version of this conversation in which you are judged for having it.
What treatment looks at
Medication is one part of the work. These are assessed and addressed alongside it, because they are frequently what makes recovery hard to sustain.
- Cravings and withdrawal symptoms
- ADHD
- Anxiety
- Depression
- Trauma
- Other behavioral health concerns
- The physical effects associated with substance use
- The emotional effects associated with substance use
Treating the substance use alone, without the conditions underneath it, is a common reason treatment does not hold.
How the care works
Start with a conversation
An assessment of your history, your health and what you want treatment to do for you. No requirement to have already stopped, and no requirement to have a plan before you call.
Medication for opioid use disorder
Sublocade® and Brixadi® are long-acting injections of buprenorphine that can lessen cravings and withdrawal symptoms, supporting recovery over the longer term. Sublocade is given once a month; Brixadi can be given weekly or monthly. Which is right for you is decided with you.
Treat what travels with it
Assessing and addressing contributing conditions — ADHD, anxiety, depression, trauma and other behavioral health concerns — as part of the same plan rather than as separate referrals.
Stay in contact
