Low cost home ketamine detox: While it may be possible in limited circumstances, usually, our expert addictions clinicians would advise against this.

Home treatment may not be the best option

A low cost home ketamine detox is not advisable due to the severe withdrawals.

The withdrawals from Ketamine are considered to be the most destructive of any drug.

Trying to deal with these at home will be extremely difficult and you are incredibly unlikely not to relapse.

It has nothing to do with willpower, but more to do with science.

What is Ketamine?

Ketamine is an anaesthetic.

It has been around for many decades and is widely used in human and animal medicine.

Often used by specialist roadside medical assistance teams, Ketamine tends to be used for emergency amputations and to anaesthetise people in road traffic collisions.

Ketamine is for lions, tigers and elephants

Vets used it to sedate animals, especially lions, tigers and other big cats.

While it is now used, in a micro dose, to heighten the effects of psychotherapy, Ketamine is not a harmless party drug.

It is cheap, widely available and very dangerous.

What Does Ketamine do?

As with other drugs and medicines (as well as alcohol) Ketamine works on receptors in the brain.

In this case theN-Nitrosodimethylamine (NDMA) receptors.

When the receptors are full of Ketamine, the naturally occurring chemical Glutamate is blocked from moving around.

Glutamate increase

This leads to an increase of the Glutamate which leads to sedation and blocking of pain signals. Undertaking a low cost home ketamine detox could be extremely painful without medical supervision.

Tolerance to Ketamine

If you keep using Ketamine your brain receptors will adapt to its presence.

You can’t just stop using it

If you stop using it the brain is forced to make immediate adjustments: Which it cannot.

As such mixed signals are sent and the result is withdrawal.

Drinking water, going for a run, drinking coffee, none of these things will help.

The brain cannot cope and it will take time to adjust.

If you stop using Ketamine, expect the following:

Signs of Ketamine Withdrawal

  • Extreme cravings
  • Intense mood swings
  • Chronic insomnia
  • Rapid onset depression
  • Intense fatigue
  • Crippling nausea
  • Marked tremor
  • Profuse sweating
  • Chest pain
  • Dangerously high body temperature

Signs of Ketamine Overdose

Because Ketamine is an anaesthetic, it is possible to overdose which, sadly, can be fatal. The signs of a Ketamine overdose are:

  • Breathing has stopped or is very slow
  • Unconsciousness
  • Low blood pressure
  • Slow heart rate
  • Non stop vomiting
  • Seizures
  • Coma

What is the Treatment For Ketamine Overdose?

At this time there is no emergency drug paramedics or hospital staff can administer to reverse the effects of Ketamine.

There is no reversal agent

Care consists of monitoring and, if necessary, intubation.

Sometimes activated charcoal is given to induce vomiting.

Never attempt to make yourself sick (or someone else) and the risk of choking will be very high.

A low cost home ketamine detox is not a substitute for professional care in case of overdose.

What is the Timeline For Ketamine Withdrawal?

There are four known phases of Ketamine withdrawal. The first of which will start within 24 hours after you stop using it:

  • Initial phase: This can be within 24 to 72 hours and the first thing you are likely to experience are cravings for Ketamine. Other features at this time are anxiety, general discomfort and restlessness.
  • Peak symptoms: Usually between day one and day three, the withdrawals will become far more intense and difficult to manage. People often hallucinate, experience extreme paranoia as well as crushing fatigue, chronic insomnia and very rapid mood swings. There will also be intense nausea.
  • Stabilisation Phase: After four days (and up to two weeks) the symptoms should start to recede. However, the desire to use will continue as will the depressive thoughts.
  • Extended phase: This can last for months and usually includes the same symptoms as the stabilisation phase.

Key Takeaways

  • Low cost home ketamine detox is not recommended due to severe withdrawal symptoms that are difficult to manage without professional support.
  • Ketamine withdrawal can lead to extreme cravings, mood swings, insomnia, and physical symptoms like nausea and tremors.
  • Seeking help from healthcare professionals is crucial; detoxing from ketamine carries significant risks without supervision.
  • Residential treatment for ketamine addiction is often more cost-effective and safer than attempting a home detox.
  • Find Me a Rehab offers free advice and referrals for those struggling with ketamine addiction and seeking professional support.

What Does a Ketamine Detox Involve?

Unlike Alcohol or other drugs there is no medicated assisted withdrawal (detox) for Ketamine.

Medication to come off Ketamine safely

Instead, supportive/adjunctive medication is used to control the symptoms of withdrawal.

This is usually, depending on the patient, a mix of benzodiazepines, beta blockers and cyclopyrrolones.

Symptom management

Medication for nausea and vomiting is also provided.

Usually, these medications are prescribed on an “as and when” basis. In a rehab centre, there are staff on hand, 24/7, to provide these.

Where necessary, your addictions clinician can adjust your medication.

At home Ketamine treatment is very risky

Low cost home ketamine detox methods should never be attempted without the supervision of professionals, as they do not provide the medical support needed for severe withdrawal symptoms.

What is The Most Effective Treatment for Ketamine Addiction?

In short: Go to a rehab centre.

Ketamine is dangerous: You must have professional help to detox

Withdrawal from Ketamine is something that needs the input of professionals: An addictions clinician, trained medical and nursing staff, therapists and 24/7 support staff.

Don’t put yourself at risk

Many patients will tell you that the withdrawals from Ketamine are so debilitating that when they tried to do it, at home, they relapsed just to get some relief.

Low cost home ketamine detox may be tempting, but it carries significant risks without the support of healthcare professionals.

Can I Be Treated at Home For Ketamine Addiction?

That all depends on how much you are using and how long you are using it for.

In any event, you would need very close support and monitoring.

You will also need therapy to understand the underlying reasons as to why you are using.

If you add the cost of clinicians appointments, medication (private prescription fees) and therapy it is actually cheaper to go into a rehab centre.

Residential treatment may be cheaper and is certainly safer

There are centres that provide a weeks treatment for just over £1,600.

When you add everything together that you would need at home, the residential option is not only more cost effective, but much, much safer.

The added benefits of residential treatment

At home you will not have a clinician on hand, 24 hour support staff, nurses, therapists, therapy groups or aftercare. Your family, loved ones and friends, no matter how well intentioned they are, simply won’t be able to provide the right care.
