Can You Combine Ketamine Therapy With Lithium, Aripiprazole, or Cariprazine? Safety, Rationale, and How Clinicians Do It

Many patients ask a practical question once ketamine therapy is on the table: If I’m already on lithium, aripiprazole, or cariprazine, can I keep taking those while I start ketamine treatment? The short answer is that many people do combine them under supervision. These medicines act through different pathways, and plans are tailored to your history, goals, and safety needs. 

The short answer

Yes, many patients remain on augmentation medications while beginning ketamine therapy. Clinicians often combine treatments when mechanisms do not overlap and when the plan can be monitored safely. At Lumin Health, we ensure that all decisions are individualized. Your Lumin Health care team will review current meds, side effects, and the timing of ketamine treatment to create a plan that will work best for you.

How the augmentation medicines work: a guide in plain language)

Lithium

• A mood stabilizer that can augment antidepressants in persistent depression.
• Often chosen to support mood stability and reduce relapse risk.
• Requires periodic blood tests and monitoring of kidneys and thyroid.
  
  

Aripiprazole and cariprazine

• Low‑dose dopamine and serotonin modulators used to augment SSRIs or SNRIs.
• Often selected when energy, drive, or anxiety remain stuck after an antidepressant trial.
• Monitoring includes restlessness, metabolic labs, and side effects that your prescriber will track.
  
  

These are daily at‑home medicines. They build gradually over days to weeks and do not change consciousness.

How ketamine therapy works and why it can pair well with meds

Ketamine therapy uses low doses of ketamine to engage glutamate pathways that may support short‑term neuroplasticity. Some patients feel shifts in mood or reactivity within hours to days. Others notice changes later. At Lumin Health, ketamine treatment generally takes two forms:

• Esketamine (Spravato): FDA‑approved intranasal dosing for treatment‑resistant depression. It is delivered only in a certified site like Lumin Health with vital sign checks and observation. We refer to this as Spravato treatment.
  
  
• Off‑label ketamine: Intramuscular ketamine dosing in clinic with monitoring. Protocols are personalized by diagnosis and response.

Because augmentation meds and ketamine for depression act through different systems, clinicians sometimes combine them to widen the chance of benefit when medical history and tolerance permit. Combination is not required, but it can be one reasonable option when safety and logistics line up.

Safety first: what clinicians review before combining ketamine treatment and augmentation meds

A careful review keeps combination care grounded and safe.

• Medication list and interactions. Your Lumin Health care team will confirm any current doses of lithium, aripiprazole, cariprazine, and antidepressants. They will look for side effects that could be amplified and plan how to monitor them.
  
  
• Vitals and medical history. Blood pressure, heart history, pregnancy status, and other conditions inform timing and dose choices for ketamine treatment.
  
  
• Labs and levels. If you take lithium, expect periodic bloodwork. For atypicals, teams monitor metabolic markers and restlessness.
  
  
• Dosing‑day guidance. With Spravato treatment, you will stay at Lumin Health for roughly 2 hours after Spravato administration to ensure monitoring is comprehensive. 
• Simplify when needed. In some cases a prescriber may adjust or pause a medicine during a trial to reduce side effect burden or to clarify what is helping. There is no one rule. Plans are individualized.

If you include psychotherapy or other behavioral support, many patients place short, focused sessions in the neuroplasticity window 24–72 hours after dosing. That timing keeps the week humane while giving you a chance to practice one or two skills.

Real‑world combination models of Spravato and augmentation medications

These examples show how clinicians commonly coordinate augmentation meds with ketamine therapy. Always confirm details with your prescriber.

Model A: Maintain augmentation, add ketamine treatment

• Keep lithium, aripiprazole, or cariprazine stable.
• Begin Spravato treatment twice weekly for four weeks, then taper if helpful. Or start an off‑label IV/IM induction per clinic protocol.
• Reassess at weeks 2, 4, and 6 to decide whether to continue, taper, or switch.

Model B: Partial response on meds → add Spravato

• If augmentation gives a modest lift but symptoms persist, add Spravato treatment as the next step while maintaining current meds.
• Introduce brief psychotherapy or skills practice 24–72 hours after dosing to support functioning.
  
  

Model C: Responded to ketamine → review meds

• After an initial response to ketamine for depression, continue augmentation at first.
• If stability holds, discuss dose simplification later. Decisions depend on functioning, side effects, and your goals.
  
  

Sample scheduling patterns (so the week feels doable)

Assume Tue/Thu Spravato treatment during induction plus morning home meds.

• Monday: Routine morning meds. Light work or school. Prep logistics for Tuesday’s dose.
• Tuesday: Morning meds as prescribed. Spravato treatment mid‑afternoon with observation. Pre‑arranged ride home. Quiet evening.
• Wednesday: Late start if possible to maximize rest. Hydration, gentle movement.
• Thursday: Morning meds. Spravato treatment mid‑afternoon. Observation. Ride home. Short journaling or a values‑based activity.
• Friday: Optional 30–50 minute psychotherapy or skills coaching to use the neuroplasticity window.
• Weekend: Recovery, connection, and brief check‑ins about what felt more possible this week.

If you receive off‑label intramuscular ketamine treatment at Lumin Health, adapt the cadence to your dosing days and clinic timing.

When not to combine right now

Combination care is not always the first step.

• Unstable medical status or side effects that need attention before adding a new element.
• Adherence strain where transportation, childcare, or work make safe observation unrealistic on dose days.
• Diagnostic ambiguity that calls for focused assessment before layering treatments.

In these situations, teams often sequence: start one path, reassess, and add the other later if needed.

What to ask your prescriber of augmentation meds (mini checklist)

• Do I need any medication timing changes on Spravato days?
• What labs or monitoring should we plan while I’m combining treatments?
• What are our decision checkpoints at weeks 2, 4, and 6?
• If ketamine therapy helps, when might we simplify or adjust augmentation?
• How can psychotherapy or behavioral support fit without overloading the week?

FAQs

Can I stay on lithium during Spravato treatment?
Often yes. Lithium can be continued while you receive Spravato treatment, but only with clearance from both your lithium prescriber and Lumin Health. Your prescriber will coordinate labs and monitoring.

Do aripiprazole or cariprazine reduce the benefits of ketamine therapy?
Not typically. These medicines and ketamine therapy act through different pathways. Your team will still watch for side effects and adjust as needed.

Who manages side effects – Lumin Health or my psychiatrist?
Both coordinate with your permission. Lumin Health will manage dosing‑day monitoring and immediate effects. Your prescribing clinician manages daily medicines and longer‑term side effects.

Will I need to stop augmentation meds if ketamine for depression helps?
Not necessarily. Many patients continue medicines during a ketamine series and review simplification later if function is steady.

Can I add psychotherapy while I’m combining treatments?
Yes. It is optional. Many patients use one brief session within 24–72 hours after dosing to practice a small, values‑based skill.

Is combination care safer than a single treatment?
Safety depends on your medical history and monitoring. Combination care can be done safely when planned well. Your team will guide timing and follow‑up.

A humane way to move forward with augmentation meds and ketamine therapy 

Combining augmentation with ketamine treatment is common in real‑world care, and it does not have to make your life more complicated. This guide contains some guiding principles of how to start with a plan you can keep, with tenets such as placing Spravato treatment on predictable afternoons, keeping home meds steady unless your prescriber adjusts them, and using the neuroplasticity window for one small skill each week. 

If it helps, continue. If not, you can pivot. Lumin Health delivers ketamine therapy and ketamine for depression, including Spravato, and coordinates with your psychiatrist so you do not have to carry the whole plan alone.
