Vasovagal
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..

People who suffer from vasovagal needle phobia fear the sight, thought, or feeling of needles or needle-like objects. The physiological changes associated with this type of phobia also include feeling faint, sweating, dizziness, nausea, pallor, tinnitus, panic attacks, and initially high blood pressure and heart rate followed by a plunge in both at the moment of injection. 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. People become more afraid of the side effects of low blood pressure caused by the idea of a needle. A study in the medical journal Circulation concluded that in many patients with this condition (as well as patients with the broader range of blood/injury phobias), 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.

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.
