Vasovagal needle phobia

Today started out just like any other summer day off, except for the fact that I was up at 4AM because I couldn’t sleep. I had a coffee at 6AM then somehow went back to bed till 830. I figured out the reason why I wasn’t able to sleep, and I’ll talk about that in my next post (hint, it has to do with a new supplement I tried).


It was my weekly IV therapy day today, so I had 2 cups of coffee (I know, not just my usual 1) then headed off to see my doctor. Because I had IV therapy done in my right arm the last 2 weeks, and it was looking pretty bruised, I suggested we try my left arm today. Why? God only knows! What ensued was my type of nightmare – first she heated up the area to get the veins to “pop” up, which they didn’t, and then she felt around for a while, and even though I could tell she couldn’t see or feel any, she poked me anyways. First time, she couldn’t find anything, so she began to poke me a second time – that was GAME OVER! I felt my head start to buzz, I was dizzy, I had cold sweats, and I told her I was going to faint. She said it’s ok, grabbed me some apple juice which I guzzled down, she put a cold cloth behind my head, had a nurse come and put my feet up and help monitor me, at which point I passed out briefly and then immediately came back to reality (slowly). She was VERY good about the entire situation, and I was incredibly embarrassed. She asked what I ate that morning, to which I replied with “nothing” because I can’t seem to eat in the mornings. Well, that will be the first and last time I do that. The sugar in the food I would have eaten could have potentially prevented me from fainting.

So we didn’t do the IV therapy, but she did inject me with the needle in my butt which helps my cells generate energy, and therefore, reduce my fatigue levels. She was going to inject the severe pain in my mid back with magnesium, but after I fainted, she decided it would be best if we left that for another day.

Good times eh? As you may have read in my article a couple weeks ago, I am terrified of having needles poked into my veins, and so are my brothers (they tend to pass out too). So I researched this phenomenon and found out we are NOT the only ones who experience this. This “situation” is called “Vasovagal needle phobia” and I’ve read a bit about it below to help you better understand whether you are one of these like myself, or if any of your family members suffer as well. Funny how I can have 30 needles injected into my neck and back on a bi-weekly basis, but I can’t handle a needle in my vein. The two are clearly distinctly classified differently in my brain!


Fear of needles

The condition was officially recognized in 1994 in the DSM-IV as a specific phobia of blood / injection / injury type. Phobic level responses to injections cause sufferers to avoid inoculations (this used to be me but I’m fine with those now), blood tests (I avoid these like the PLAGUE – my last bloodwork was done 4 years ago), and in the more severe cases, all medical care.

It is estimated that at least 10% of American adults have a fear of needles, and it is likely that the actual number is larger, as the most severe cases are never documented due to the tendency of the sufferer to avoid all medical treatment.

Vasovagal type of needle phobia is a type of needle phobia uniquely characterized by a two-phase vasovagal response. First, there is a brief acceleration of heart rate and blood pressure. This is followed by a rapid plunge in both heart rate and blood pressure, sometimes leading to unconsciousness (hence what happened to me today). The loss of consciousness is sometimes accompanied by convulsions and numerous rapid changes in the levels of many different hormones.



Although needle phobia is defined simply as an extreme fear of medically related shots/injections, it appears in several varieties.


Although most specific phobias stem from the individuals themselves, the most common type of needle phobia, affecting 50% of those afflicted, is an inherited vasovagal reflex reaction. Approximately 80% of people with a fear of needles report that a relative within the first degree exhibits the same disorder (my brothers).

People who suffer from vasovagal needle phobia fear the sight, thought, or feeling of needles or needle-like objects. The primary symptom of vasovagal fear is vasovagal syncope, or fainting due to a decrease of blood pressure.

Many people who suffer from fainting during needle procedures report no conscious fear of the needle procedure itself, but a great fear of the vasovagal syncope reaction. A study in the medical journal Circulation concluded that in many patients with this condition, an initial episode of vasovagal syncope during a needle procedure may be the primary cause of needle phobia rather than any basic fear of needles. These findings reverse the more commonly held beliefs about the cause-and-effect pattern of needle phobics with vasovagal syncope.

The physiological changes associated with this type of phobia also include feeling faint, sweating, nausea, tinnitus, panic attacks, and initially high blood pressure and heart rate followed by a plunge in both at the moment of injection.

Although most phobias are dangerous to some degree, needle phobia is one of the few that actually kill. In cases of severe phobia, the drop in blood pressure caused by the vasovagal shock reflex may cause death. In a 1995 article on needle phobia, the author was able to document 23 deaths as a direct result of vasovagal shock during a needle procedure. Crazy right?!

The best treatment strategy for this type of needle phobia has historically been desensitization or the progressive exposure of the patient to gradually more frightening stimuli, allowing them to become desensitized to the stimulus that triggers the phobic response.  


Associative fear of needles is the second most common type, affecting 30% of needle phobics. This type is the classic specific phobia in which a traumatic event such as an extremely painful medical procedure or witnessing a family member or friend undergo such, causes the patient to associate all procedures involving needles with the original negative experience (hence what happened to me while being diagnosed with fibromyalgia – too many negative experiences associated with needles!)

This form of fear of needles causes symptoms that are primarily psychological in nature, such as extreme unexplained anxiety, insomnia, preoccupation with the coming procedure and panic attacks. Effective treatments include cognitive therapy, hypnosis and/or the administration of anti-anxiety medication. I’m sure the cipralex I’m on for anxiety and depression is helping, and the fact that I trust this doctor also helps, but it’s this ingrained fear of needles in my veins that I can’t compute in my brain!


Resistive fear of needles occurs when the underlying fear involves not simply needles or injections but also being controlled or restrained. It typically stems from repressive upbringing or poor handling of prior needle procedures i.e. with forced physical or emotional restraint.

This form of needle phobia affects around 20% of those afflicted. Symptoms include combativeness, high heart rate coupled with extremely high blood pressure, violent resistance, avoidance and flight. The suggested treatment is psychotherapy, teaching the patient self-injection techniques or finding a trusted health care provider.



Hyperalgesic fear of needles is another form that does not have as much to do with fear of the actual needle. Patients with this form have an inherited hypersensitivity to pain, or hyperalgesia. To them, the pain of an injection is unbearably great and many cannot understand how anyone can tolerate such procedures.

This form of fear of needles affects around 10% of needle phobes. The symptoms include extreme explained anxiety, and elevated blood pressure and heart rate at the immediate point of needle penetration or seconds before. The recommended forms of treatment include some form of anesthesia either topical or general. This is partly my issue as well –  my Naturopathic Doctor takes my blood pressure and heart rate beforehand and it is THROUGH the roof, then once it’s all said and done it’s normal again 🙂


Whilst witnessing procedures involving needles it is possible for the phobic present to suffer the symptoms of a needle phobic attack without actually being injected. Prompted by the sight of the injection the phobic may exhibit the normal symptoms of vasovagal syncope and fainting or collapse is common (I can’t watch this). While the cause of this is not known, it may be due to the phobic imagining the procedure being performed on themselves. Recent neuroscience research shows that feeling a pin prick sensation and watching someone else’s hand get pricked by a pin activate the same part of the brain.

Comorbidity and triggers

Fear of needles, especially in its more severe forms, is often comorbid with other phobias and psychological ailments; for example, iatrophobia or an irrational fear of doctors, is often seen in needle phobic patients.

A needle phobic patient does not need to physically be in a doctor’s office to experience panic attacks or anxiety brought on by needle phobia. There are many triggers in the outside world that can bring on an attack through association. Some of these are blood (me), injuries, the sight of the needle physically or on a screen (me), paper pins (me), examination rooms, hospitals, white lab coats, hospital gowns, doctors, dentists, nurses, the antiseptic smell associated with offices and hospitals, the sight of a person who physically resembles the patient’s regular health care provider, or even reading about the fear (me).


The medical literature suggests a number of treatments that have been proven effective for specific cases of needle phobia, but provides very little guidance to predict which treatment may be effective for any specific case. The following are some of the treatments that have been shown to be effective in some specific cases:

  • Ethyl Chloride Spray: (and other freezing agents). Easily administered, but provides only superficial pain control.
  • Jet injectors: Jet Injectors work by introducing substances into the body through a jet of high pressure gas as opposed to by a needle. Though these eliminate the needle, some people report that they cause more pain. Also, they are only helpful in a very limited number of situations involving needles i.e. insulin and some inoculations.
  • Iontophoresis: Iontophoresis drives anesthetic through the skin by using an electric current. It provides effective anesthesia, but is generally unavailable to consumers on the commercial market and some regard it as inconvenient to use.
  • EMLA: EMLA is a topical anesthetic cream that is a eutectic mixture of lidocaine and prilocaine. It is a prescription cream in the United States, and is available without prescription in Canada and some other countries. Although not as effective as iontophoresis, since EMLA does not penetrate as deeply as iontophoresis-driven anesthetics, EMLA provides a simpler application than iontophoresis. EMLA penetrates much more deeply than ordinary topical anesthetics, and it works adequately for many individuals. I have tried this as the suggestion of my friend who works in medicine and it froze my arm really well before I went in to give blood. I will be buying more of this for my next IV treatment!! I bought it over the counter at Shopper’s Drug Mart in Canada.
  • Ametop: Ametop gel appears to be more effective than EMLA for eliminating pain during venepuncture.
  • Lidocaine and tetracaine patch: A self-heating patch containing a eutectic mixture of lidocaine and tetracaine is available in several countries, and has been specifically approved by government agencies for use in needle procedures. The patch is sold under the trade name Synera in the United States and Rapydan in European Union. Each patch is packaged in an air-tight pouch. It begins to heat up slightly when the patch is removed from the packaging and exposed to the air. The patch requires 20 to 30 minutes to achieve full anesthetic effect. The Synera patch was approved by the United States Food and Drug Administration on 23 June 2005.
  • Behavioural therapy: Effectiveness of this varies greatly depending on the person and the severity of the condition. There is some debate as to the effectiveness of behavioral treatments for specific phobias (like blood, injection, injury type phobias), though some data are available to support the efficacy of approaches like exposure therapy. Any therapy that endorses relaxation methods may be contraindicated for the treatment of fear of needles as this approach encourages a drop in blood pressure that only enhances the vasovagal reflex. In response to this, graded exposure approaches can include a coping component relying on applied tension as a way to prevent complications associated with the vasovagal response to specific blood, injury, injection type stimulus.
  • Nitrous oxide (laughing gas): This will provide sedation and reduce anxiety for the patient, along with some mild analgesic effects. I was given laughing gas before I had my wisdom teeth taken out surgically at 18 and it made it much easier to handle the needle going in my arm. I’m just not sure whether this contributed to my after surgery nausea!
  • Inhalation general anesthesia: This will eliminate all pain and also all memory of any needle procedure. On the other hand, it is often regarded as a very extreme solution. It is not covered by insurance in most cases, and most physicians will not order it. It can be risky and expensive and may require a hospital stay.
  • Benzodiazepines such as diazepam (Valium) or lorazepam, may help alleviate the anxiety of needle phobics. These medications have an onset of action within 5 to 15 minutes from ingestion. A relatively large oral dose may be necessary. If my fear of needles continues, and the other therapies I try to do not work, I MIGHT ask my doctor about this just to calm my nerves a bit. 


The funny part about all of this is the fact that my fiance Bart has NO TROUBLE what so ever with needles, so much so, that he is a regular blood donor, going every 6 weeks! He is in and out in no time. I envy this part of him!! I would love to be able to donate blood but A. I’m on medications that are contraindicated and B. I would pass out every time I tried to donate my precious A- blood lol. We’ll see how I do through the coming years.

I see my doctor in 2 weeks time and I’ll let you know how that goes using the EMLA cream!

We are off to Niagara Falls tomorrow – should be a great day!

Xoxo Lex
