Trypanophobia is a type ofphobiathat involves a severe fear of needles or anxiety related to injections and medical care involving the use of needles. This can be problematic both because of the symptoms and because some people delay or avoid necessary medical care due to fear and anxiety.Trypanophobia is also sometimes referred to as needle phobia.

The most telling symptom of trypanophobia is an extreme aversion to needles, sometimes severe enough that it interferes with seeking and accepting medical care, or it interferes with life. There are other symptoms, too, including physical symptoms.

How Phobia Is Diagnosed
It is estimated that roughly 3.5 percent to 10 percent of people have trypanophobia; 80 percent of people with trypanophobia have a close relative with a phobia of injections as well.There can be a genetic component to the phobia.
Another cause is a previous traumatic experience with injections, possibly a response that causes them to faint or nearly faint. There is possibly an evolutionary response to the dangers of sharp objects puncturing the skin.The cause of trypanophobia partially depends on the type.
There are multiple types of trypanophobia that vary in traits and causes:
Vasovagal Trypanophobia
Vasovagal trypanophobia is a type of trypanophobia that involves a vasovagal reaction. A vasovagal reaction is when a person experiences a sudden increase and then decrease of heart rate and blood pressure. The changes in heart rate and blood pressure can cause fainting.
It is not entirely clear if the vasovagal response causes vasovagal trypanophobia or if trypanophobia causes the vasovagal response. However, it is believed that this fainting response is inherited and then leads to a phobia of injections due to associating them with the negative experience of fainting, which creates a cycle. In extremely rare cases, this type of trypanophobia can lead to heart attack or stroke.
Associative Trypanophobia
Associative trypanophobia is a type of trypanophobia linked to a traumatic event.A person with this fear of injections may have experienced a medical procedure that was extremely painful or had a severe reaction to a previous injection, for example. Less commonly, the person with associative trypanophobia may have been with someone else who experienced an extremely painful medical procedure or injection reaction.
Resistive Trypanophobia
Resistive trypanophobia is a type of trypanophobia that involves a fear of being controlled. The cause could be previous needle experiences that required them to be restrained, most commonly during childhood.
Some people with this type of trypanophobia may become aggressive or violent when in situations involving injections, which may result in the need for them to be restrained to prevent injury to themselves or others. In this type of trypanophobia, there is a fear of both the needle and the control or restraint.
Hyperalgesic Trypanophobia
Hyperalgesic trypanophobia is a type of trypanophobia linked to an increased feeling of physical pain or increased sensitivity to the physical pain.Children tend to feel the physical pain of injections more intensely than adults.
Vicarious Trypanophobia
Vicarious trypanophobia is a type of trypanophobia that involves an extreme fear of injections when someone else is experiencing the encounter with the needle.
Treatment options for trypanophobia include therapy and medications. There are also coping strategies that may help to prevent fears and anxieties and to lessen their severity when they do occur.
List of Common and Unusual Phobias
Therapy
Cognitive behavioral therapy, or CBT, is an effective psychotherapy treatment often used for trypanophobia. It involves strategies that consider the connections between thoughts, behaviors, and emotions.
This treatment may also include systematic desensitization therapy (i.e., exposure therapy), which uses increasing levels of exposure to the fear in a safe, controlled environment in order to lessen the fear response.Hypnosis has also been found to be effective.
Medication
When needles are needed, sometimes a medication is applied to the skin first so the pain sensation is lessened or not felt at all. When sedation is needed for an operation or procedure, the patient may be sedated prior to the use of any needles. However, this can increase the problem as the patient does not have control or the opportunity to overcome the phobia.
Medication is generally avoided for treating phobias because psychotherapy options tend to be more effective and do not come with the side effects. When medications are used, it is typically for short-term use. Antidepressants such as selective serotonin reuptake inhibitors, orSSRIs, or beta-blockers are sometimes prescribed for anxiety.
If you or a loved one are struggling with trypanophobia, contact theSubstance Abuse and Mental Health Services Administration (SAMHSA) National Helplineat1-800-662-4357for information on support and treatment facilities in your area.
Relaxation techniques are recommended for coping with trypanophobia, except in people who experience vasovagal trypanophobia. This is because relaxation techniques can decrease heart rate and blood pressure.
A Word From Verywell
Trypanophobia can be a frightening, life-altering experience. It is also a serious medical issue. Without treatment, you delay necessary medical care.
Talk to your doctor about how to receive care without needles or with minimal use of needles. Depending on your medical needs, needle injections may not be necessary. If needles are necessary for your care, there are coping and treatment options to help you overcome trypanophobia and receive the care you need.
