Ketamine therapy has gained widespread recognition for its transformative potential in treating mental health conditions like depression, PTSD, and anxiety, as well as chronic pain. Two common methods of administering ketamine in clinical settings are intravenous (IV) and intramuscular (IM). Both approaches have proven effective, but each offers distinct experiences and benefits. At Innerbloom Ketamine Therapy in San Luis Obispo, California, we offer both IV and IM ketamine, allowing patients to choose the method that best suits their needs. In this post, we’ll explore the differences in experience, efficacy, safety, and patient preference between IV and IM ketamine.
IV Ketamine: IV ketamine therapy is often described as a more gradual, controlled experience. The dose is administered slowly through an infusion, and because it can be adjusted throughout the infusion, patients often find this method easier to tolerate. The duration of an IV session can range from 40 minutes to an hour, with most people reporting a slow onset (within 4-5 minutes) of effects that peak gradually. Patients often experience vivid imagery and introspective thought patterns, but the setting and dosing are closely monitored by the care team, allowing adjustments if needed.
IM Ketamine: IM ketamine involves an injection of ketamine into the muscle such as the deltoid, which leads to a faster onset of effects compared to IV. Many patients describe the experience as more intense, with a quicker (within 1-2 minutes) escalation into the psychedelic state. While the effects may be powerful and brief, lasting around 30-45 minutes, IM sessions can feel more immersive. Some patients prefer the quicker, more pronounced peak, especially if they’ve undergone several sessions and know what to expect.
IV Ketamine: IV ketamine is considered the gold standard for ketamine therapy due to it's 100% bioavailability and the ability to carefully titrate the dosage over time. This allows for precise control over the experience, making it easier to tailor the treatment to each patient’s specific needs. For individuals with severe depression or treatment-resistant conditions, the gradual nature of IV ketamine can lead to a more sustained and predictable response.
For individuals with chronic pain, research suggests that higher doses and longer infusions can provide more effective pain relief, making IV ketamine the preferred option for those seeking pain management as the primary goal of their therapy.
IM Ketamine: IM ketamine also demonstrates significant efficacy, particularly for patients seeking a shorter, more concentrated experience. While IV is often preferred in medical settings for its titratable nature, IM ketamine can be equally effective in managing mood disorders.
IV Ketamine: In terms of safety, IV ketamine offers the advantage of continuous monitoring and control over the dosage. Should any adverse reactions occur, adjustments can be made immediately by slowing or stopping the infusion. This high level of control makes IV ketamine a preferred option for those concerned with minimizing risks or for individuals new to ketamine therapy.
IM Ketamine: IM ketamine is also considered safe, but the rapid onset and intensity of the experience mean that patients should be well-prepared for its effects. Since the entire dose is administered in one shot, adjustments cannot be made once the injection is given. However, in a well-controlled clinic environment with proper screening and aftercare, IM ketamine remains a safe and viable option.
IV Ketamine: Many patients who prefer IV ketamine appreciate the gradual onset and the ability to receive ongoing monitoring during the session. The slow infusion allows for a more controlled experience, making it an excellent choice for first-timers or those who may be nervous about the intensity of a ketamine session. The extended duration also provides a longer therapeutic window, which can be advantageous for integrating insights from the psychedelic experience.
IM Ketamine: For patients who are more familiar with ketamine therapy or prefer a shorter, more intense session, IM ketamine can be an attractive option. The rapid onset can feel more immersive and impactful, which appeals to those looking for a powerful, yet time-efficient experience.
IM sessions are often favored by individuals who are fearful of IV insertion or have difficult IV access due to their anatomy.
Choosing between IV and IM ketamine often comes down to personal preferences, treatment goals, and specific medical needs. Patients seeking a gradual, controlled experience with the ability to adjust the dosage may find IV ketamine to be the best option, especially for those new to ketamine therapy. On the other hand, patients looking for a faster, more intense session or those experienced with ketamine may prefer IM for its rapid onset and shorter session length.
