Ketamine therapy has emerged as a promising treatment for various mental health conditions, offering hope to those who have not found relief through traditional methods. Among the different forms of ketamine administration, ketamine lozenges (sometimes referred to as ketamine troches) have gained significant attention for their convenience, but also for the risks this administration route poses. In this blog post, we will explore what ketamine lozenges are, how they work, the associated risks, and why proper monitoring and prescribing by qualified healthcare providers are crucial for ketamine therapy.
What is Ketamine Therapy?
Ketamine therapy involves the use of ketamine, a powerful anesthetic, to treat psychiatric disorders such as depression, anxiety, and post-traumatic stress disorder (PTSD). While ketamine is primarily known for its use in anesthesia, it has been found to have rapid-acting antidepressant effects when used in lower doses. This off-label use of ketamine for mental health conditions has shown significant promise, with many patients experiencing immediate improvement in their symptoms.
Off-label use refers to the prescription of a drug for a condition or in a manner not specifically approved by the U.S. Food and Drug Administration (FDA). Although ketamine is not FDA-approved for psychiatric conditions, its off-label use is legal and has been supported by numerous studies and clinical trials.
Ketamine Routes of Administration
Ketamine can be administered through various routes, each with its own absorption characteristics and benefits. Understanding these routes is essential for determining the most appropriate method for each patient.
- Intravenous (IV) Infusion: IV infusion is one of the most common methods of administering ketamine for psychiatric treatment. In this method, ketamine is delivered directly into the bloodstream through an IV line. This route allows for precise control over the dosage and rapid onset of effects, typically within minutes. The bioavailability of IV ketamine is by definition 100%, making it highly effective for acute symptom relief.
- Intramuscular (IM) Injection: IM injection involves administering ketamine into a muscle, usually the thigh or upper arm. This method also provides relatively quick absorption, with effects typically felt within 5 to 10 minutes. The bioavailability of IM ketamine is lower than IV, but it still offers a rapid and effective treatment option for patients who may not have access to IV therapy.
- Nasal Spray: Esketamine, a derivative of ketamine, is available as a nasal spray and is FDA-approved for treatment-resistant depression. The nasal spray allows for easy self-administration and has a bioavailability of approximately 45%. This route is convenient for patients who prefer not to undergo injections or infusions. There are numerous studies comparing the effectiveness of ketamine vs esketamine.
- Oral Lozenges: Ketamine lozenges, also known as troches, are designed to dissolve slowly in the mouth, allowing for sublingual (under the tongue) or buccal (between the gum and cheek) absorption. This method provides a more gradual onset of effects, typically within 20 to 30 minutes, and has a bioavailability of around 30%.
The Importance of Monitoring and Prescribing by Providers
While ketamine therapy offers significant benefits, it is not without risks. The FDA has issued warnings about the potential hazards associated with the unsupervised use of compounded ketamine, including adverse reactions such as elevated blood pressure, respiratory depression, and urinary tract issues. Therefore, it is crucial that ketamine therapy, in all administration forms, is given under the supervision of trained and licensed healthcare providers.
Providers play a vital role in ensuring the safe and effective use of ketamine therapy. They are responsible for:
- Assessing Patient Eligibility: Not all patients are suitable candidates for ketamine therapy. Providers must conduct thorough evaluations to determine if ketamine is an appropriate treatment option.
- Monitoring Treatment: Regular monitoring is essential to track the patient’s response to treatment and adjust dosages as needed. This helps to minimize the risk of adverse effects and optimize therapeutic outcomes.
- Providing Informed Consent: Patients must be fully informed about the potential risks and benefits of ketamine therapy. Providers should ensure that patients understand the treatment process and any associated risks.
- Ensuring Proper Administration: Regardless of the administration method, ketamine therapy should be conducted according to established protocols to ensure safety and efficacy.
Safety of In-Person Ketamine Therapy

In-person ketamine therapy under the supervision of healthcare providers is considered safer for patients because it reduces the risk of adverse events. The FDA has expressed concerns about the at-home use of compounded ketamine products, including oral formulations (ketamine lozenges), for the treatment of psychiatric disorders. According to the FDA:
FDA is aware of increased interest in the at-home use of compounded ketamine products, including oral formulations, for the treatment of psychiatric disorders. Patients and healthcare providers should be aware that FDA has identified potential safety concerns associated with the use of compounded ketamine products from compounders and telemedicine platforms, including abuse and misuse, psychiatric events, increases in blood pressure, respiratory depression, and lower urinary tract and bladder symptoms. Home use of compounded ketamine products presents additional risk because onsite monitoring by a healthcare provider is not available.
In-person therapy ensures that patients are closely monitored by trained professionals who can promptly address any adverse reactions or complications. This level of supervision is crucial for maintaining patient safety and optimizing treatment outcomes. Healthcare providers can:
- Monitor Vital Signs: Regular monitoring of blood pressure, heart rate, and oxygen levels helps detect any immediate adverse effects.
- Adjust Dosages: Providers can adjust dosages in real-time based on the patient’s response, ensuring the treatment remains effective and safe.
- Provide Immediate Support: In the event of a psychiatric or physical adverse reaction, healthcare providers can offer immediate intervention and support.
In conclusion, ketamine lozenges offer a convenient option for ketamine therapy, but they pose additional risks due to the lack of in-person supervision. By working with qualified professionals, patients can safely benefit from the transformative potential of ketamine therapy.
