How Old Do You Have To Be For Ketamine Therapy?

Ketamine therapy has become one of the most talked about treatments for conditions like depression, anxiety, and PTSD. In recent years, it has moved from being an anesthetic used in hospitals to a treatment option in mental health clinics across the United States. According to the National Institute of Mental Health, more than 21 million adults in the U.S. experienced at least one major depressive episode in 2021, and for some, standard treatments have not worked. 

This is where ketamine therapy comes in, offering hope when other options have failed. While its benefits are becoming better known, the rules about who can get it  especially when it comes to age can be confusing. That’s why understanding the age guidelines for ketamine therapy is so important before considering it as a treatment option.

Why Age Matters in Ketamine Therapy

Age plays a big role in how doctors decide if someone is ready for ketamine therapy. It’s not just about following a number, it’s about making sure the treatment is safe and effective for each person.

Our bodies and brains change a lot as we grow. For younger people, the brain is still developing, and certain treatments can have different effects compared to adults. For older adults, other health conditions or medications might affect how their body responds to ketamine. Because of this, doctors look at age as one of the first things when deciding if ketamine is the right choice.

There’s also the question of rules and approvals. The FDA has approved a specific type of ketamine treatment, called Spravato (esketamine), only for adults 18 and older. That means clinics have to follow strict guidelines for those treatments. However, regular ketamine is sometimes used “off label” for teenagers in special cases, but that decision is always made very carefully after medical evaluation and, for minors, with parental consent. 

Minimum Age Requirements for Ketamine Treatment

Age can set the starting point for whether someone is considered for ketamine therapy. While there’s no single rule for all clinics, there are some widely followed guidelines based on safety and FDA approval.

Spravato (Esketamine) – FDA Approval for 18+

Spravato, the nasal spray version of ketamine, has clear rules set by the U.S. Food and Drug Administration (FDA). It’s only approved for adults who are 18 or older. This form of treatment is mainly used for people with treatment-resistant depression or depression linked to suicidal thoughts. Because it’s FDA-approved, clinics have to follow this age limit. If someone is under 18, they cannot receive Spravato unless new research or approvals change this rule in the future.

Off-Label Ketamine Use for Teens (Ages 13–17)

The rules for regular ketamine (given through IV infusions or lozenges) are a little different. While it’s not officially approved by the FDA for depression in teens, some doctors use it “off-label.” This means they use their professional judgment to prescribe it when other treatments haven’t worked and the potential benefits outweigh the risks. In these cases, careful medical evaluation is key, and parents or guardians must give consent. Many clinics set their own lower age limit often around 13 or 14  ut it varies.

Rare Cases for Children Under 13

Ketamine therapy for children under 13 is very rare. It’s generally only considered in extreme situations, such as severe depression or suicidal thoughts that haven’t improved with any other treatment. Because the brain is still developing at this age, doctors are extra cautious. If it is used, it’s done under close medical supervision and usually in a hospital setting rather than a regular clinic.

Maximum Age Limit, Is There One?

Unlike the minimum age, there’s no hard cut-off for when someone is “too old” for ketamine therapy. Still, age can affect how the body responds, and doctors take that into account when deciding on treatment.

Ketamine Use in Older Adults (60+)

There’s no official maximum age for ketamine therapy, and many older adults have safely received it. In fact, it can be helpful for depression in later life, especially when other treatments haven’t worked. However, as we age, our bodies process medications differently. This means doctors may start with lower doses or monitor closely for side effects like changes in blood pressure or dizziness.

Health Conditions That May Affect Suitability

Even though age itself isn’t a strict barrier, certain health conditions can influence whether ketamine therapy is a good idea. Heart problems, uncontrolled high blood pressure, or certain cognitive issues may require extra caution. Before starting treatment, doctors review your full medical history, medications, and any other conditions to make sure ketamine will be safe and beneficial.

Conclusion

Age is an important part of deciding if ketamine therapy is the right choice, but it’s only one piece of the puzzle.
