Contraindications for Ketamine Therapy

A contraindication refers to a specific condition where a treatment or medication should not be used due to potential risks. For ketamine infusion therapy, the following contraindications apply:

1. Uncontrolled Hypertension (High Blood Pressure): Ketamine can raise blood pressure, making it unsuitable for individuals with uncontrolled hypertension, as it may lead to dangerous spikes.
2. History of Stroke or Aneurysm: Due to its potential to elevate blood pressure, ketamine is contraindicated for patients with a history of stroke or aneurysm, as it could increase the risk of recurrence or rupture.
3. Severe Heart Disease: Ketamine can affect heart function and increase heart rate, making it inappropriate for individuals with severe heart disease or heart failure.
4. Schizophrenia or Psychosis: Ketamine may cause hallucinations and dissociative effects, potentially worsening symptoms in individuals with schizophrenia or psychotic disorders.
5. Pregnancy: Ketamine is not recommended during pregnancy due to potential risks to the developing fetus (more details below).
6. Severe Liver Disease: Since ketamine is processed by the liver, individuals with severe liver disease may experience heightened side effects or toxicity.

Drug-to-Drug Interactions

Ketamine therapy can interact with other medications, potentially leading to harmful side effects or reducing the effectiveness of either treatment. To ensure your safety, it is crucial to inform your healthcare provider about all medications you are currently taking, including over-the-counter drugs, herbal remedies, and dietary supplements. Some significant drug interactions to be aware of include:

1. Benzodiazepines (e.g., Xanax [alprazolam], Valium [diazepam]): These medications may reduce the therapeutic benefits of ketamine, particularly when it is used to treat depression or anxiety.
2. Opioids (e.g., OxyContin [oxycodone], Vicodin [hydrocodone]): Combining opioids with ketamine increases the risk of serious side effects, such as respiratory depression (slowed breathing) and excessive sedation.
3. Barbiturates (e.g., Phenobarbital): These drugs can decrease ketamine’s effectiveness and amplify the risk of sedation.
4. Antidepressants (e.g., Prozac [fluoxetine], Zoloft [sertraline]): Certain antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs), may interact with ketamine and increase the likelihood of serotonin syndrome, a potentially life-threatening condition caused by excessive serotonin in the brain.
5. Antihypertensives (e.g., Lopressor [metoprolol], Norvasc [amlodipine]): These medications may interact with ketamine, leading to unpredictable changes in blood pressure.

Ketamine in Pregnancy

Is Ketamine Therapy Safe During Pregnancy?

Ketamine is generally not recommended for use during pregnancy. Animal studies have indicated potential risks to fetal development, including impaired brain growth. While research on ketamine use in pregnant humans is limited, the potential risks often outweigh the benefits. If you are pregnant or planning to become pregnant, it is important to discuss alternative treatment options with your healthcare provider. If you are currently undergoing ketamine therapy, consult one of our telemedicine providers as soon as possible to explore safer alternatives.

Ketamine While Breastfeeding

Is Ketamine Treatment Safe While Breastfeeding?

There is limited data on the safety of ketamine use while breastfeeding. It is unclear whether ketamine passes into breast milk, but due to the potential for serious side effects in nursing infants, it is generally advised to avoid ketamine therapy during this time. If you are breastfeeding and considering ketamine treatment, consult one of our telemedicine providers to discuss safer options for you and your baby.

Estimated Cost of Ketamine Therapy

The cost of ketamine therapy can vary depending on the formulation and dosage prescribed. For example, a 30-day supply of ketamine nasal spray (Spravato) typically costs between $600 and $900 without insurance when using a GoodRx coupon. Injectable ketamine, which is commonly administered in clinical settings such as ketamine clinics, may have a different pricing structure. For the most accurate cost information, check with your pharmacy or the ketamine clinic where you plan to receive treatment.

Possible Alternatives to Ketamine Therapy

If ketamine infusion therapy is not a suitable option for you, there are several alternative treatments and lifestyle changes that may help manage your condition. Always consult your healthcare provider before making any changes to your treatment plan. You can also schedule a telemedicine appointment with one of our providers to discuss these alternatives in detail.

1. Depression: Alternatives include selective serotonin reuptake inhibitors (SSRIs) such as Prozac (fluoxetine) or serotonin-norepinephrine reuptake inhibitors (SNRIs) like Cymbalta (duloxetine). Non-medication options, such as cognitive-behavioral therapy (CBT) and lifestyle changes like regular exercise and a balanced diet, may also be beneficial.
2. Anxiety: Medications such as Lexapro (escitalopram) or Ativan (lorazepam) may be prescribed. Additionally, mindfulness practices, yoga, and stress management techniques can provide relief.
3. PTSD: Treatment options include trauma-focused therapies, such as EMDR (Eye Movement Desensitization and Reprocessing), and medications like Zoloft (sertraline). Support groups and mindfulness exercises may also help.
4. Chronic Pain: Alternatives include non-opioid pain relievers such as Lyrica (pregabalin) or Neurontin (gabapentin). Physical therapy, acupuncture, and lifestyle adjustments, such as weight management, can also be effective.
5. Bipolar Disorder: Common treatments include mood stabilizers like Lithobid (lithium) or antipsychotics such as Seroquel (quetiapine). Psychotherapy and maintaining a consistent sleep schedule are also key components of managing this condition.
6. Suicidal Ideation: Immediate intervention is critical. Antidepressants like Prozac (fluoxetine) or mood stabilizers may be prescribed. Crisis counseling and support from mental health professionals are essential for safety and recovery.
7. Obsessive-Compulsive Disorder (OCD): First-line treatments include SSRIs such as Zoloft (sertraline) or Prozac (fluoxetine). Cognitive-behavioral therapy (CBT) with exposure and response prevention (ERP) is also highly effective.
8. Substance Use Disorder: Treatment options may include medications like Suboxone (buprenorphine/naloxone) for opioid addiction, along with behavioral therapies such as cognitive-behavioral therapy (CBT) or motivational interviewing.
9. Migraine: Alternatives include triptans such as Imitrex (sumatriptan) or preventive medications like Topamax (topiramate). Lifestyle modifications, such as avoiding known triggers, staying hydrated, and maintaining a regular sleep schedule, can also help reduce the frequency and severity of migraines.
10. Fibromyalgia: Medications like Lyrica (pregabalin) or Cymbalta (duloxetine) may alleviate symptoms. Incorporating regular exercise, stress management techniques, and a nutritious diet can also play a significant role in managing this condition.
