Can You Take Ketamine With ADHD Medication? A Safety Guide

Can You Take Ketamine While On ADHD Medication?

Yes, if a licensed clinician determines it is medically appropriate, in most cases you can take ketamine while on an ADHD medication regimen. Stimulants like Adderall do not automatically disqualify you; your provider reviews them during screening.

Ketamine therapy uses a medication delivered inside a supervised program to help treat conditions like depression and anxiety. If the treatment is new to you, this overview of what ketamine is explains the basics.

Drug labeling treats this pairing as one to monitor rather than avoid. Ketamine's own prescribing information flags that sympathomimetics, the class ADHD stimulants belong to, can add to its cardiovascular effects,² and the label for esketamine, a closely related molecule, is more explicit still, advising close blood-pressure monitoring with psychostimulants.¹ The reason for that coordination is a shared effect on blood pressure and heart rate, which the next section explains.

How Ketamine And ADHD Stimulants Interact In The Body

Some people notice a temporary rise in blood pressure and heart rate during a ketamine session. That happens because both ketamine and ADHD stimulants act on your body's catecholamine system, the network that uses signaling chemicals such as norepinephrine and dopamine.

Stimulants raise those chemicals to improve focus, and ketamine increases sympathetic activity as well. According to ketamine's prescribing information, ketamine "increases blood pressure, heart rate, and cardiac output" through the inhibition of catecholamine reuptake.² The most important place this shows up is your cardiovascular system.

The Main Concern: Blood Pressure And Heart Rate

For most people, the rise in blood pressure and heart rate during a ketamine session is modest and short-lived. The concern with a stimulant is that its effect can add to ketamine's, not that either one is dangerous on its own.

A 2021 meta-analysis by Vankawala and colleagues measured the typical change at the sub-anesthetic doses used in psychiatric treatment. Across 2,252 treatments, systolic blood pressure rose about 12.6 mmHg, diastolic about 8.5 mmHg, and heart rate about 4 beats per minute, and the increases were transient, easing after treatment.³ Any elevations also tend to resolve quickly: in a report on 723 infusions, treatment-emergent blood-pressure rises typically returned to normal within about 20 minutes (Rodrigues et al. 2020).

The FDA esketamine label names this drug class directly. It states that concomitant use with psychostimulants, such as amphetamines and methylphenidate, may increase blood pressure and directs close blood-pressure monitoring.¹ In practice, that means the effect is planned for and watched, not left to chance.

ADHD Medications This Applies To

This applies most directly to stimulant medications, though the picture differs by drug class. The table below groups the common ADHD medications by how they tend to affect blood pressure and heart rate.

The takeaway is that this is not a simple stimulant versus non-stimulant split. A non-stimulant like atomoxetine can still raise blood pressure, while alpha-2 agonists lower it, so each medication is reviewed on its own.

Overstimulation And Other Possible Effects

Beyond the cardiovascular effect, some people wonder about the mental experience of combining the two. Higher arousal from a stimulant could, in theory, leave some people feeling more activated or anxious around a session.

Experiences vary. Many people find the dissociative state of a ketamine session meaningful within supervised care, while others find it unfamiliar. Preparation materials and your support person can help you navigate it.

How The Combination Is Managed Safely

Because the interaction between ketamine and ADHD medication is predictable, it can be screened for and monitored. In a supervised program, the combination is coordinated with your care team through medically supervised sessions.

Screening, Medication Review, And Monitoring

Ketamine's cardiovascular effects are well documented, and providers manage the stimulant combination with a few standard safeguards:

• Cardiovascular screening: your provider reviews your blood pressure and heart history before treatment.
• Medication review: you share every medication and dose, including your ADHD stimulant.
• Vital-sign monitoring: your blood pressure and heart rate are checked around each session.

Depending on the setting and provider, some programs ask you to hold a stimulant dose on the morning of treatment. Mindbloom requires this hold in its program. Stimulants are on Mindbloom's treatment-day list of substances to avoid, so same-day use pauses the session for a provider to review, and uncontrolled hypertension is an exclusion.

Mindbloom offers sublingual tablets and subcutaneous injections, chosen with your provider based on comfort, tolerability, and clinical fit. Its providers will not begin a session when blood pressure is above 150/100 mmHg or heart rate is over 100 beats per minute.

Ketamine's safety has been studied across large groups. In a real-world study of 11,441 Mindbloom sublingual clients, serious adverse events were recorded in 0.05% of people, and you can read a summary in Mindbloom's largest published study.⁴ Individual results may vary. The key point is that any hold is a single treatment day, not a reason to permanently stop your ADHD medication.

What To Tell Your Provider Before Treatment

Building on the screening described above, you can make your consultation easier by bringing:

• A full list of your medications and doses, including your ADHD stimulant and any supplements.
• Any cardiovascular history, such as high blood pressure, or past reactions to stimulants.
• Questions about treatment-day timing for your stimulant and when to resume it.

These details are how your provider tailors treatment to you.

Does Combining Them Change How Well Ketamine Works?

There is no dedicated study of ketamine combined with ADHD stimulants. A 2021 systematic review by Veraart and colleagues found no studies of ketamine used together with psychostimulants, so no direct effect on ketamine's results has been established.⁵

Ketamine's antidepressant effect is thought to work mainly through glutamate, a different signaling system than the one ADHD stimulants act on (Zanos and Gould 2018).⁸ Newer research suggests dopamine plays a supporting role as well, based largely on animal studies and a small human sample (Nakatsuka et al. 2025).⁶

Stimulants raise dopamine directly and strongly, while ketamine's involvement appears more indirect, so the two overlap only partly, on that one pathway. In theory a stimulant's dopamine surge could add to or blur ketamine's dopamine-related effect, which is a reason for a careful conversation with your provider, not a cause for alarm. It is not evidence that a stimulant will change your results.

Does Ketamine Treat ADHD, Or The Conditions Alongside It?

Ketamine is not an approved or established treatment for the core symptoms of ADHD. The FDA-approved uses of ketamine and esketamine do not include ADHD,² and it is used for depression, anxiety, and related conditions, not for focus or attention.

There is currently limited evidence on whether ketamine affects ADHD, and no sign that it worsens ADHD. The main thing to watch is the higher arousal described earlier, which your provider accounts for during screening.

Ketamine And Co-Occurring Depression And Anxiety

Most people with ADHD who look into ketamine are seeking help for a co-occurring condition, not for ADHD itself. A 2025 review in Frontiers in Psychiatry reports that about 70% of adults with ADHD have another mental health condition, with depression affecting 18.6% to 53.3%.⁷

Ketamine's use for depression and anxiety rests on a substantial body of peer-reviewed research, and Mindbloom has added its own real-world outcomes. In a peer-reviewed study of Mindbloom clients using sublingual ketamine, response rates were 56.4% for depression on the PHQ-9 (n=11,441) and 56.1% for anxiety on the GAD-7 (n=7,776).⁴ Individual results may vary.

Treating the co-occurring condition can ease part of the daily burden, but it does not change ADHD itself. Depending on your symptoms, that may point toward ketamine therapy for depression or ketamine therapy for anxiety.

Who Might Be A Good Candidate For Ketamine Therapy?

Eligibility is a clinical assessment, not a fixed checklist. Taking an ADHD stimulant does not automatically disqualify you from treatment.

Uncontrolled hypertension or significant heart disease may make ketamine inappropriate, which is exactly what screening checks for. A licensed provider can walk you through who is a good candidate and confirm whether treatment fits your situation.

Other Medications And Substances To Review First

ADHD medication is not the only thing worth reviewing before you start. A few other medications and substances matter for a different reason.

Benzodiazepines such as Xanax, and other central nervous system depressants including alcohol, can add sedation with ketamine and are generally avoided around sessions. The FDA ketamine label warns that combining it with these depressants can cause profound sedation.²

Whether antidepressants such as SSRIs or SNRIs fit alongside ketamine depends on your provider's review, so always disclose them. For a fuller list, see ketamine's other drug interactions.

The Bottom Line On Ketamine And ADHD Medication

Taking an ADHD medication does not rule out ketamine therapy. Stimulants do not automatically disqualify you, and the real issue is the additive, usually transient rise in blood pressure and heart rate.

A screened, monitored program manages the combination of ketamine and ADHD medication in provider-specific ways. Some programs use a one-day stimulant hold rather than a permanent stop, and Mindbloom uses a one-day hold. Ketamine treats the depression and anxiety that commonly occur alongside ADHD, not ADHD itself.
