Introduction
Ketamine has been proven to be effective for depression. But how it is given makes a big difference. It is mostly given as an IV (intravenous) or nasal spray. It works well in both ways but is expensive and requires trained staff, special equipment, and a lot of supervision.
A simpler and cheaper option? Subcutaneous ketamine injections. In this, ketamine is injected just under the skin. It has been used in various other conditions as well. Early research suggested that it could work just as well, even better than IV infusions.
What Is Subcutaneous Ketamine?
Subcutaneous (SC) ketamine is ketamine delivered through a simple injection just under the skin. It has been used in humans since 1975, mainly for pain relief, anesthesia, and post-surgery recovery. Unlike IV ketamine, subcutaneous ketamine is much easier to administer. This makes its use more convenient and safer.
The research has focused mostly on IV ketamine for depression treatment. However, SC ketamine has proven to be more effective than IV. It is simple to administer, cost-effective, and does not need special equipment or personnel. SC can be a transformative breakthrough, making ketamine therapy easily accessible for those who need it.
How Does Subcutaneous Ketamine Work?
Mechanism of Action:
Ketamine has been around for a long time. It is mainly used as an anesthetic for both people and animals. But in recent years, it has gained attention for something completely different: depression treatment. Once known mostly for its dissociative effects and recreational use, ketamine is now changing the way we think about mental health treatment. Unlike traditional antidepressants, which can take weeks or even months to work, ketamine, especially in its SC form, can bring relief within hours.
So, how does it work? Most antidepressants focus on brain chemicals like serotonin and norepinephrine. Ketamine takes a different route. It works on the glutamate system and blocks the NMDA (N-methyl-D-aspartate) receptors. It activates the AMPA (α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid) receptors, which trigger the secretion of the brain-derived neurotrophic factor (BDNF). BDNF is needed for repair, resilience, and neural growth, helping to reverse the structural and functional changes in depression.
With a quick enhancement of neural connectivity, ketamine has a fast-acting antidepressant effect, usually within hours. This mechanism is believed to be particularly important for reducing suicidal ideation, making ketamine a promising option for individuals who need urgent relief from severe depression.
If other depression treatments have failed to show any improvement in your symptoms, ketamine offers real hope for you.
How Effective Is Subcutaneous Ketamine in Depression?
Efficacy in Treating Depression:
So far, research shows that SC ketamine is highly effective. A study showed that even small doses of SC ketamine can show significant improvement. Subcutaneous ketamine is emerging as a promising alternative for treating depression, treatment-resistant depression (TRD), and suicidal ideation. While most research has focused on IV administration, studies suggest that the efficacy of SC ketamine can be just as effective, with high response and remission rates.
In one study, all patients receiving SC ketamine injections for depression showed improvement, even at doses lower than 0.5 mg/kg. Another study in older adults with TRD and bipolar depression found strong response rates and remission rates, with some patients benefiting from even lower doses. These results are comparable to IV ketamine studies, where remission rates typically range from 23 to 29 percent and response rates from 50 to 71 percent.
SC ketamine has also shown rapid antidepressant effects, similar to IV and intranasal Esketamine. Significant improvements in depressive and suicidal ideation symptoms have been reported with SC ketamine.
What Are the Side Effects of Subcutaneous Ketamine?
Side Effects:
Like other forms of ketamine administration, SC ketamine can cause temporary side effects. These are milder compared to IV ketamine. Some of the most common side effects of ketamine therapy include:
-
Feeling detached from reality or oneself (dissociation).
-
Mild hallucinations.
-
Altered perception or euphoria.
-
Confusion.
-
Increased blood pressure.
-
Increased heart rate.
-
Dizziness.
-
Nausea.
-
Vomiting.
-
Headache.
-
Fatigue or drowsiness.
These side effects of ketamine therapy are mild and short-lived. Some patients might also have mild discomfort at the injection site.
How Is Subcutaneous Ketamine Given?
Dosage and Administration:
Subcutaneous ketamine injection for depression is easier to administer. The most common ketamine dosage for depression is 0.5 mg per kg of body weight, the same as IV ketamine. It works well even with lower doses. Higher doses of SC ketamine can cause side effects like dissociation or dizziness.
SC ketamine can be given initially once or twice per week. For long-term management of depression, SC ketamine can be given once every one to four weeks, depending on the patient’s response.
How is it administered? In SC, the injection goes under the skin of the thigh or abdomen. It does not need an infusion pump or IV drip; it is just an injection. This makes it simpler and faster than other ketamines. After injection, you need monitoring for 60 to 90 minutes for side effects.
What to Expect During Treatment?
Starting SC ketamine can feel exciting but also a bit uncertain if you do not know what to expect. Here is a simple breakdown of what to expect:
-
The doctor will review your medical history and the medications you are taking.
-
You will be asked not to eat anything a few hours before the session to reduce nausea.
-
Check your blood pressure, heart rate, and others to avoid complications.
-
SC ketamine injection for depression is given under the skin of your abdomen or thigh (preferably).
-
It just takes a few seconds, and you will be asked to rest in a comfortable position while being monitored for about an hour.

Most of you start to feel better within hours.

The side effects of the SC ketamine will fade away within a day.
What to Discuss With Your Healthcare Provider?
Before starting SC ketamine, having an open and honest conversation with the doctor or specialist is essential for safe and effective treatment. You must give a detailed history of your conditions like depression, anxiety, bipolar disorder, or any other conditions. You should inform your doctor if you have high blood pressure or heart disease, are pregnant or breastfeeding, or use alcohol.
