Ketamine therapy has emerged as a beneficial treatment for various mental health conditions. However, it is not suitable for everyone. This article will explore which types of people may be ill-suited to receive ketamine treatments, and consider alternative options. <\/p>\n\n\n\n

Ketamine therapy<\/a> has gained recognition for its remarkable ability to alleviate symptoms of depression and other mental health conditions. <\/p>\n\n\n\n Unlike conventional antidepressants, which may take weeks or even months to show their effects, ketamine is rapid-acting, offering much-needed relief to individuals in distress. The therapeutic effects of ketamine tend also to be longer-lasting than conventional medication, with a single dose lasting up to two weeks. <\/p>\n\n\n\n To date, clinical trials have highlighted the effectiveness of ketamine in the treatment of depression<\/a>, suicidal ideation<\/a>, substance abuse disorder<\/a>, anxiety<\/a>, and post-traumatic stress disorder (PTSD)<\/a>.<\/p>\n\n\n\n Scientists think ketamine\u2019s therapeutic effects may be explained by its ability to increase neuroplasticity<\/a> – the ability of the brain to reorganize itself by forming new neural connections. This effect may help ketamine therapy patients overcome negative thoughts and behavior patterns. <\/p>\n\n\n\n Despite these benefits, ketamine\u2019s risk profile means the therapy could cause more harm than good in certain types of people. Ketamine increases cardiac output, the volume of blood pumped out per minute, as well as heart rate. <\/p>\n\n\n\n <\/p>\n\n\n\n Individuals with cardiovascular issues such as uncontrolled hypertension or recent heart attacks are not considered good candidates for ketamine therapy. <\/p>\n\n\n\n Ketamine has the potential to increase blood pressure and heart rate, which can pose risks for those with compromised cardiovascular health. This includes those with hypertension, tachycardia, arrhythmias and previous or family history of ischemia and cardiac arrest. <\/p>\n\n\n\n In a study on rabbits<\/a>, long-term ketamine use caused increased death of heart cells, build-up of scar tissue on the heart, and abnormal heart rhythms. The dosing and frequency of ketamine use in the study don\u2019t reflect that of real-life ketamine therapy. <\/p>\n\n\n\n However, ketamine therapy could increase the risk of substance abuse (see below) and heart problems that may arise from chronic use.<\/p>\n\n\n\n <\/p>\n\n\n\n Individuals with a personal or family history of psychotic disorders, such as schizophrenia or bipolar disorder with psychosis, are not recommended for ketamine therapy. <\/p>\n\n\n\n This is because ketamine temporarily induces psychotic-like symptoms, such as dissociation and hallucinations, which could potentially exacerbate psychosis or trigger a psychotic episode.<\/p>\n\n\n\n Increasing evidence highlights this may be a low risk. <\/p>\n\n\n\n One meta-analysis of nine ketamine studies<\/a> encompassing 41 patients with depression and a history of psychosis, the results found ketamine didn\u2019t exacerbate psychotic symptoms in this patient population. Some researchers have also begun considering whether ketamine could be helpful in the treatment of schizophrenia<\/a>.<\/p>\n\n\n\n However, while the evidence remains limited it\u2019s advised those with psychosis risk avoid ketamine. <\/p>\n\n\n\n <\/p>\n\n\n\n Active substance abuse poses a significant risk when considering ketamine therapy. As a powerful anesthetic with psychoactive properties, ketamine has the potential for misuse and addiction, particularly in individuals with a history of substance abuse. <\/p>\n\n\n\n This risk appears to be more prevalent in at-home ketamine telehealth users<\/a>, where the administration isn\u2019t supported or limited to controlled settings. <\/p>\n\n\n\n Ketamine substance abuse is associated with a host of different physical and mental health problems. This includes:<\/p>\n\n\n\n <\/p>\n\n\n\n To ensure the safety and efficacy of ketamine therapy, individuals must be in a stable recovery phase before considering treatment if they have previously had substance abuse issues.<\/p>\n\n\n\n <\/p>\n\n\n\n Because there\u2019s limited evidence to show how ketamine may affect pregnancy and breastfeeding, it is recommended to avoid ketamine in either of these conditions. Moreover, experimental animal studies<\/a> have shown that ongoing exposure to or high doses of ketamine could affect the brain and liver in a developing fetus.<\/p>\n\n\n\n <\/p>\n\n\n\n When considering ketamine therapy, it is crucial to thoroughly assess the individual’s medical history to identify any pre-existing conditions that may affect the safety or efficacy of ketamine treatment<\/a>. Medical conditions such as cardiovascular disease, liver or kidney dysfunction, or respiratory disorders may require careful monitoring or adjustment of doses in the treatment plan.<\/p>\n\n\n\n Furthermore, the medications the individual is currently taking must be evaluated for potential interactions with ketamine. Some medications may have interactions that could impact the response to ketamine therapy. <\/p>\n\n\n\nCardiovascular Issues and Ketamine Therapy<\/strong><\/h2>\n\n\n\n
