What medication can be prescribed for a patient with a fear of flying to alleviate anxiety during flight?

Medication for Fear of Flying

For a patient with fear of flying requiring medication, prescribe lorazepam 0.5-1 mg orally 30-60 minutes before boarding, with a reduced dose of 0.25-0.5 mg for elderly or debilitated patients (maximum 2 mg in 24 hours). 1, 2

Why Lorazepam is the Preferred Choice

Lorazepam is specifically recommended by the BMJ for situational anxiety like flight anxiety because it has a short half-life, rapid onset, and predictable duration of action that matches the time course of a flight. 1, 2 The oral tablets can also be used sublingually if needed, providing flexibility in administration. 2

Critical Timing and Dosing

• Administer 30-60 minutes before boarding to ensure peak effect during takeoff, which is typically the most anxiety-provoking phase of flight. 1
• For short flights, a single dose is usually sufficient. 1
• For long-haul flights crossing time zones, consider timing medication with airline meals and adjusting to local time upon arrival. 1

Important Safety Warnings

Avoid alcohol completely before and during the flight, as it interacts with benzodiazepines, worsens cognitive function, and can precipitate disinhibition or acute confusional states. 2, 1 This is a common pitfall that significantly increases adverse event risk.

Avoid excessive caffeine consumption, which may worsen anxiety and has diuretic effects that can lead to dehydration at altitude. 2, 1

Why NOT Alprazolam

While alprazolam is widely used in the US for anxiety disorders 3, research specifically on flight phobia shows that alprazolam paradoxically increases physiological activation under acute stress conditions and hinders therapeutic effects of exposure. 4 In a controlled study of flight phobics, alprazolam increased heart rate (114 vs 105 bpm) and respiratory rate (22.7 vs 18.3 breaths/min) compared to placebo during the first flight, and on the second flight, the alprazolam group experienced substantially more panic attacks (71% vs 7%). 4 This makes alprazolam a poor choice for situational flight anxiety.

Non-Pharmacological Strategies to Combine

Always combine medication with practical flight preparation strategies, as these significantly reduce anxiety burden and medication requirements:

• Book direct flights in late morning or early afternoon to minimize disruption to daily routines and avoid fatigue-related anxiety amplification. 1, 2
• Request aisle seats for easier movement and reduced feelings of confinement. 1, 2
• Consider early boarding to reduce time pressure and allow settling in without crowds. 2
• Use earplugs or eye masks during flight to reduce sensory overstimulation. 1, 2
• Ensure appropriate hydration but avoid excessive fluid intake that necessitates frequent bathroom trips. 1, 2

Special Populations

For elderly patients (typically >65 years), reduce the lorazepam dose to 0.25-0.5 mg with a maximum of 2 mg in 24 hours due to increased sensitivity to benzodiazepines and higher risk of confusion, falls, and paradoxical agitation. 1, 2

For patients with cognitive impairment or dementia, benzodiazepines carry significant risk of precipitating delirium in the aircraft environment. 2 These patients require a familiar caregiver throughout the journey and may need airline medical clearance. 2, 5

When Medical Clearance is Required

Obtain airline medical clearance via MEDIF form if the patient:

• Has other medical conditions that may be adversely affected by the flight environment 1
• Cannot care for themselves independently 5
• Has a behavioral condition that may pose a hazard to other passengers 5

Common Pitfalls to Avoid

• Do not prescribe benzodiazepines for long-term use in anticipation of future flights, as this leads to tolerance and dependence. 3 Prescribe only for the specific flight(s) needed.
• Do not use benzodiazepine patches in opioid-naive patients or for acute situational anxiety, as they take too long to reach steady state. 2
• Do not combine multiple sedating medications without careful consideration of additive effects.
• Do not assume the patient understands alcohol restrictions—explicitly counsel against any alcohol consumption. 2, 1

Alternative Considerations

For patients with contraindications to benzodiazepines or those seeking non-benzodiazepine options, behavioral therapy with systematic desensitization is the gold standard treatment for specific flying phobia and should be considered for patients with recurrent need to fly. 6 SSRIs like fluoxetine have shown benefit in case reports for resolving fear of flying, particularly when comorbid depression or panic disorder is present, but require weeks of treatment to achieve effect. 7
