So, how often is it that you get injected with Ketamine for pain? This depends on the severity of pain, their body’s response to the previous injections, how long the effects last, and the type of pain. In some cases, multiple infusions are given over a period of days and in other cases, they may have a few follow-on infusions if they experience symptoms again. No one schedule fits all.
The use of ketamine infusions for the treatment of some forms of chronic pain is being discussed, particularly when other treatments have not been effective enough. But it’s crucial to keep in mind your goals, medications you are taking, your health, and any side effects you are concerned with when determining the right schedule.
Knowing what your options are begins with learning how ketamine works, what an infusion schedule might look like, and which questions to ask your qualified healthcare professional.
Key Takeaways
- No specified timetable. The frequency of ketamine infusions varies depending on the nature of the pain, person-to-person response and general well-being.
- The first sessions can be combined. Depending on the condition, the series of infusions may be given over several days.
- Benefits vary. The relief may last for days, weeks, or longer, but some will feel little or no relief.
- Each maintenance session is a one on one meeting. If there is some benefit that is not significant, and if the benefits outweigh the risks, then follow-up infusions may be considered.
- Safety matters. Ketamine must be administered under the supervision of a professional as it can have an impact on blood pressure, heart rate, alertness and perception.
- Assessment is important as it should be done on a regular basis. The aim is to try to decide if the advantages outweigh ongoing infusion.
How Often Do You Get Ketamine Infusions for Pain?
How often ketamine infusions are given varies for each person. A healthcare professional might recommend a series of tests for the initial diagnosis and then a reassessment. Occasional follow-up infusions may be indicated if the infusions offer some relief to the patient.
For instance, some pain regimens consist of multiple infusions given over a couple of consecutive days. Other methods provide fewer sessions as needed based on the condition and the person’s reaction. These examples are not a recommended course of treatment for all patients.
There are three factors that guide the decision:
- Different types of pain respond differently – nerve-related pain, complex regional pain syndrome (CRPS) and other chronic pain issues might be affected by the treatment.
- Duration of relief: An individual who gets lasting relief may not require another infusion right away, whereas a person whose symptoms come back quickly may require another infusion right away.
- Safety and tolerability: Side effects, other health issues, prior medications, and reactions to previous sessions determine if further infusions are needed.
It’s not just about how often infusions can be administered. It’s whether or not every session is significant enough and is improving things for long enough to make the risks worthwhile.
What Does a Typical Ketamine Infusion Schedule Look Like?
A specific time frame cannot be specified for all forms of chronic pain. There are however three stages of infusion plans.
1. Initial Infusion Series
A series of infusions over several days is given at the beginning of some protocols. The aim is to observe the individual’s reaction and determine if the improvement is worthwhile to pursue further.
How many sessions, the duration, amount/strength of the infusion, and the spacing between sessions will vary based on the condition being treated and the individual administering. More sessions does not equal better results.
2. Reassessment After the Initial Series
Following the initial sessions, the health care professional checks for shifts in pain, functioning, sleep, mobility and general health.
A pain diary is helpful. Write down how much you are in pain, if you sleep well, if you can do normal daily activities and any side effects. The following information will help you to decide if the benefits are important.
If there is not significant improvement, it may not be beneficial to repeat the same schedule. This next step might be reviewing other options, not just making sure that additional infusions are arranged.
3. Maintenance or Follow-Up Infusions
People may get their symptoms back after a short period of time. In some cases, a professional may decide to administer another injection once he or she is sure the person is responding and safe.
No one standard maintenance interval is accepted. Follow-up might be considered after a period of days or weeks, or it may not be appropriate at all. The time frame should be determined by a solid evaluation, not a set timeline.
Infusions to maintain should not be considered as lifelong treatment. They should be evaluated periodically.
How Long Does Pain Relief From Ketamine Infusions Last?
The relief lasts from short term to long term. Others see improvement for a short period and others may see improvement last for weeks or longer. Others may not see any improvement.
The duration of effect can vary depending on a number of factors:
- There are different processes at play with different conditions and some may react differently.
- Previous response: Duration of relief from previous sessions can help inform future decisions.
- Dose, duration, number of sessions: This may impact response.
- Overall health: Other illnesses, drugs, sleep and activities of daily living can affect a person’s feelings.
- Individual differences: People react differently to the same situation.
Additionally, it is worth recognizing the acute effects of ketamine and its potential effects on pain. A change in sensation or perception which occurs during infusion does not imply a change in sensation or perception which will follow in the long term.
If symptoms return rapidly, it is not a good idea to double the dosage; instead, contact your health care professional.
Which Types of Pain May Respond to Ketamine Infusions?
There have been several studies investigating ketamine as a treatment for chronic pain, especially chronic nervous system pain.
Complex Regional Pain Syndrome
Complex regional pain syndrome (CRPS) can result in chronic pain that persists longer and is more intense than would be anticipated after an injury. There is some evidence that ketamine infusions can provide benefits for some individuals suffering from CRPS, but the efficacy and effect of the infusion is variable.
Neuropathic Pain
Neuropathic pain occurs when nerves are damaged or are not working properly. Burning, tingling, electric-shock sensations or pain upon light contact can occur.
Ketamine interacts with NMDA receptors which are important for pain signalling. That’s one of the reasons why it’s been of interest for certain types of nerve problems. But it is not equally effective into all neuropathic diseases.
Other Persistent Pain Conditions
Scientists have also tried ketamine in treating fibromyalgia and some types of chronic back pain. There is conflicting evidence and it will vary by condition, prior treatments and health.
Ketamine does not always work to treat chronic pain. In a specific case, careful consideration needs to be given to whether the evidence warrants its use.
What Affects How Often You May Need an Infusion?
A number of factors can affect the interval between sessions.
The strength of the response
If the pain and daily activities improve significantly, another infusion may not be necessary soon. When benefits are restricted, a professional may re-evaluate the plan.
How long the benefits last
Any return of symptoms can provide guidance to reassess but should not automatically lead to another session. Whether it’s because of return of pain or the person’s overall condition is also a factor.
Side effects
Some side effects of Ketamine include nausea, dizziness, drowsiness, altered perception and brief elevated blood pressure and heart rate. Excessive use also poses risks of bladder and urination issues, liver effects, and misuse.
Other medications and health conditions
Considerations for suitability of ketamine include the presence of existing medications, cardiovascular issues, liver issues, urinary issues, and past substance-related issues.
Functional improvement
Unfortunately, the score of pain is not the whole story. Improved sleep, mobility, concentration and ability to function in daily life may give a more complete picture of the benefits of the infusions.
Are More Frequent Ketamine Infusions Better?
Not necessarily. The more frequent the infusions, the more intense or persistent the pain will be.
There may be significant side effects when using ketamine and repeated use needs to be considered. If someone increases the frequency for no apparent reason he or she could be putting him or herself at further risk without any additional gain.
A good plan should establish the criteria for improvement, how improvements will be gauged and when the strategy needs to be reviewed. When benefits are short and intermittent, or outweighed by risks, maintaining the same treatment plan may not be a good choice.
Do not increase or decrease infusion frequency, dose, or infusion schedule without the advice of the person who is supervising your care.
What Should You Expect During a Ketamine Infusion?
Ketamine Infusion is where ketamine is given through a vein over a period of time. The dosage and length of treatment are determined by the purpose and the treatment plan chosen by the health care provider.
While receiving an infusion, you might get dizzy, feel sick to your stomach, feel sleepy, have blurred senses, or feel like things are happening to you but you are not part of it. Others may find themselves feeling anxious or confused.
During and after the session may require monitoring of your blood pressure, heart rate, alertness and overall response. Additionally, you should be given clear instructions regarding transportation, driving, alcohol and other activities following the infusion.
Ketamine may change the way you perceive or coordinate your movements, arrange for transportation if directed and do not drive until cleared to do so.
Before you begin, you should ask about how long the sessions will last, how you will be monitored, what side effects you can expect, and how you will determine if you are responding to the sessions.
What Are the Risks of Repeated Ketamine Infusions?
Risks of exposure are related to the dose of the substance, frequency of exposure, duration of exposure, personal health status, and other substances or medications present.
Some immediate (short-term) effects may be:
- Nausea or vomiting
- Dizziness or drowsiness
- Temporary rise in blood pressure/heart rate
- Confusion or a change in the way things are perceived
- A feeling of anxiety or distress while the infusion is being given
Exposure or chronic use may cause other issues such as urinary tract and bladder complications, liver effects, misuse or dependency on ketamine.
If you have urinary symptoms that you don’t experience before, blood in the urine, severe abdominal pain, or other symptoms that concern you after repeated exposure, contact medical care immediately. If the symptom is severe, chest pain, difficulty breathing or loss of consciousness, seek emergency help.
Prior to an infusion series, talk with your health care provider about your complete health history and the medications you take. As the project progresses, continuous reassessment will be used to establish whether the possible benefits remain worth the risks.
How Do You Know When It Is Time for Another Infusion?
However, the return of pain is just one factor. Before the next session, the professional in charge of your care should check out the previous response, how long it took to improve, any side effects, and changes in your health.
Think of the following questions to follow up throughout the session:
- Is my pain reduced to where I can live my life better?
- How many days did it take to improve?
- Were there any side-effects?
- Do I have the ability to sleep, move, work or engage in normal activities more comfortably?
- Is it worthwhile in terms of the time, money and possible risks involved?
These observations can be used to make discussions more specific and useful. They can also help to determine if a new strategy is needed.
The aim is not to have an infusion as frequently as is possible. The objective is to discover a safe, evidence-based method that will enable significant improvements to be achieved.
