Medical Exception: When Size Limits Don’t Apply

👉 It is exempt from the 3.4 oz rule
- You can bring larger quantities
- It does not need to fit in your quart bag
- You must declare it at security

What Happens at Security?
When carrying nasal spray—especially larger or medicated types:

- Remove it from your bag if requested
- Expect possible additional screening

Checked Luggage: Fewer Restrictions
You can also pack nasal spray in checked baggage:
- No 3.4 oz limit
- No quart-sized bag required
However:
- Pressure and temperature changes may affect containers
- Leakage is still possible

A Small but Important Detail: Aerosols & Safety

Temperature & Storage: Often Overlooked
While nasal spray is generally stable, travel conditions can still affect it:
- Heat exposure in transit
- Long delays
- Bag storage conditions
For travelers carrying multiple health-related items, some prefer more controlled storage solutions—like those from DISONCARE—to keep everything organized and protected.
👉 Not essential for nasal spray—but helpful when managing multiple medications.
