Panic attack + Diclazepam
Diclazepam is known to produce panic attack, a cognitive effect. A panic attack is a discrete episode of acute, overwhelming fear or terror that arises suddenly and peaks within minutes, accompanied by distressing physical symptoms including rapid heartbeat, shortness of breath, chest tightness, trembling, dizziness, and a profound sense that one is dying, going insane, or losing control.
About Panic attack
A panic attack is one of the most acutely distressing experiences a person can undergo during psychoactive substance use. It manifests as a sudden, overwhelming wave of fear or terror that arrives without proportionate external cause and rapidly escalates to peak intensity within minutes. The psychological experience of extreme fear is accompanied by a cascade of physical symptoms that can be genuinely frightening: pounding or racing heart,shortness of breath or a feeling of being unable to get enough air,chest pain or tightness,trembling or shaking,dizziness or lightheadedness,numbness or tingling in the extremities,sweating,nausea, and a sensation of choking. Many people experiencing their first panic attack are genuinely convinced they are having a heart attack or dying.
The overlap between panic attack symptoms and genuine cardiovascular emergencies is a significant complicating factor, because the fear of dying that accompanies a panic attack produces physiological responses (adrenaline release, further tachycardia, hyperventilation) that intensify the very symptoms causing the fear — creating a positive feedback loop that can sustain or escalate the attack. The person notices their heart racing, interprets this as evidence of a heart attack, becomes more terrified, which makes their heart race faster, which increases their certainty that something is medically wrong.
In the context of substance use, panic attacks can be triggered through several mechanisms. Pharmacological triggers — stimulants, cannabis (particularly in higher doses or in inexperienced users), and psychedelics can directly activate the neurological circuits underlying panic through excessive adrenergic, serotonergic, or cannabinoid receptor stimulation.Psychological triggers — the disorientation, loss of control, and unfamiliar perceptual changes produced by many substances can activate existential fear responses.Physiological triggers — real but benign physical effects of substances (elevated heart rate, altered breathing patterns, vasomotor changes) can be misinterpreted as medical emergencies, triggering panic.
Panic attacks during substance use are most commonly associated with cannabis (one of the most frequent triggers, especially for newer or infrequent users),psychedelics (particularly during the come-up or at unexpectedly high doses),stimulants (both during acute effects and during comedowns),caffeine (at high doses), and can occur duringwithdrawal from depressants (alcohol, benzodiazepines). A first panic attack during substance use can sometimes sensitize the person to future panic attacks, even when sober.
Harm reduction note: If you or someone you are with is having a panic attack during substance use, the most important intervention is calm reassurance. Tell them: this is a panic attack, it is caused by the substance, it will pass, they are not dying, and their heart is fine. Encourage slow, controlled breathing (in for 4 counts, hold for 4, out for 4). Change the environment if possible — move to a quieter, cooler, less stimulating space. A benzodiazepine, if available and if there are no contraindicated substances in the mix, is the standard pharmacological intervention. Most panic attacks resolve within 20-30 minutes even without intervention. If genuine uncertainty exists about whether the symptoms represent a panic attack or a medical emergency, err on the side of seeking medical evaluation.
