Why Medication Management Matters in Ketamine Therapy
Most patients who seek ketamine therapy are already taking one or more psychiatric medications — antidepressants, anxiolytics, mood stabilizers, or sleep aids. Managing these existing medications alongside ketamine treatment requires careful coordination, and doing so through telehealth adds another layer of complexity that patients and providers must navigate together.
Ketamine can interact with other medications in ways that affect both safety and efficacy. A thoughtful medication management plan is not optional; it is a core component of responsible ketamine treatment.
Common Medication Interactions with Ketamine
Benzodiazepines
Benzodiazepines (such as lorazepam, clonazepam, and diazepam) are among the most clinically significant interactions with ketamine. Research published in Biological Psychiatry suggests that benzodiazepines may blunt ketamine's antidepressant effects by interfering with the glutamate signaling pathways that ketamine activates. Many providers will ask you to skip your benzodiazepine dose on the day of treatment, though this should only be done under medical supervision.
MAO Inhibitors
Monoamine oxidase inhibitors (MAOIs) such as phenelzine and tranylcypromine carry a risk of hypertensive crisis when combined with ketamine. If you are currently taking an MAOI, most ketamine providers will require a washout period before beginning treatment. This transition must be carefully supervised, as abruptly stopping MAOIs can cause withdrawal symptoms.
SSRIs and SNRIs
Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are generally considered safe to use alongside ketamine. Some preliminary research suggests these medications may even complement ketamine's effects. However, your provider should be aware of all antidepressants you take to monitor for any unusual responses.
Lamotrigine
Lamotrigine, a mood stabilizer commonly prescribed for bipolar disorder, may reduce ketamine's dissociative and antidepressant effects according to some studies. If you take lamotrigine, your provider may need to adjust your ketamine dosing or timing.
Opioids
Patients taking opioid medications (for chronic pain or opioid use disorder treatment) require special consideration. Both ketamine and opioids affect the central nervous system, and combining them increases the risk of respiratory depression and excessive sedation. Providers experienced in ketamine therapy will carefully evaluate opioid use and may adjust dosing protocols accordingly.
Stimulants
ADHD medications such as amphetamine and methylphenidate can increase heart rate and blood pressure. Since ketamine also raises cardiovascular parameters, the combination requires blood pressure monitoring. Most providers will ask you to skip your stimulant on treatment days.
How Telehealth Providers Manage Medications Remotely
Comprehensive Medication Review
Before your first ketamine session, a responsible telehealth provider will conduct a thorough medication review. This should include:
- All prescription medications — psychiatric and non-psychiatric
- Over-the-counter supplements — including St. John's Wort, which affects serotonin
- Recreational substance use — alcohol, cannabis, and other substances that may interact with ketamine
- Dosage and timing — when you take each medication relative to your proposed treatment schedule
Be completely honest during this review. Omitting medications — even ones that seem unrelated — can compromise your safety. For more on the intake process, see our first session guide.
Tapering and Transitioning Medications
Some patients begin ketamine therapy with the goal of eventually reducing or discontinuing other psychiatric medications. This is a valid treatment objective, but tapering must be done gradually and under close supervision.
Key principles for medication transitions during ketamine therapy:
- Never stop a medication abruptly without your provider's explicit guidance
- Taper one medication at a time to isolate the effects of each change
- Maintain regular check-ins — telehealth makes frequent short appointments feasible
- Track symptoms daily during any transition period
- Have a reversal plan — know what to do if symptoms worsen during a taper
Coordinating with Other Prescribers
One of the most important aspects of medication management in telehealth ketamine therapy is communication between providers. Your ketamine prescriber may not be the same clinician who manages your antidepressant, mood stabilizer, or anxiety medication.
Ensure coordination by:
- Giving each provider a complete list of your medications and all prescribers
- Signing release-of-information forms so providers can communicate directly
- Asking your ketamine provider whether they have contacted your other prescribers
- Using a single pharmacy when possible, as pharmacists can flag interactions

Red Flags in Medication Management
Be cautious if a telehealth ketamine provider:
- Does not ask about your current medications during intake
- Prescribes ketamine without reviewing your medication list with you
- Tells you to stop other medications abruptly without a tapering plan
- Refuses to coordinate with your other providers or dismisses the importance of doing so
- Does not monitor you during medication transitions
- Has no protocol for adverse interactions — ask what happens if you experience a negative reaction

Special Populations
Patients on Multiple Psychiatric Medications
Polypharmacy (taking multiple psychiatric medications simultaneously) is common among treatment-resistant depression patients — the very population most likely to seek ketamine therapy. If you take three or more psychiatric medications, your provider should take extra care with dosing, timing, and monitoring. Telehealth can actually facilitate this through more frequent, shorter check-in appointments.
Older Adults
Adults over 65 metabolize medications differently and are more susceptible to drug interactions. Kidney and liver function changes with age can affect how quickly ketamine and other drugs are cleared from the body. If you are an older adult, ensure your provider adjusts protocols accordingly and monitors cardiovascular parameters closely.
Patients with Chronic Pain
Many chronic pain patients take complex medication regimens including opioids, gabapentinoids, muscle relaxants, and anti-inflammatories. Ketamine has analgesic properties of its own, and introducing it may change your pain medication needs over time. This should be managed collaboratively with your pain management provider.
Practical Steps for Patients
- Create a medication list — Include drug name, dose, frequency, prescriber, and reason for taking it. Update it before every appointment.
- Use a medication tracking app — Apps like Medisafe or MyTherapy can help you log doses and flag interactions.
- Set up a pre-session checklist — Note which medications to take, skip, or adjust before each ketamine session.
- Keep a symptom journal — Record mood, side effects, sleep quality, and any unusual symptoms daily during treatment.
- Ask questions — If you do not understand why a medication change is being made, ask your provider to explain.
The Bottom Line
Medication management is one of the most critical safety aspects of telehealth ketamine therapy. A responsible provider will conduct thorough medication reviews, coordinate with your other prescribers, and monitor you closely during any transitions. As a patient, your role is to be fully transparent about what you take and to follow tapering instructions carefully.
