When should I take Sudafed before a flight?

Take 1 Sudafed tablet about 2 hours before landing. Spray nose with Otrivine well about 1 hour and then again 30 minutes before landing. Try to clear nasal ear passage by holding nose, blow out cheeks with mouth closed and swallow.

1. About one hour before expected descent, take a decongestant (such as Sudafed- 12hr). 2. About 30 minutes before the flight use a nasal spray (such as Afrin or Neo-Synephrine).

Spray Afrin nasal decongestant spray twice into each nostril one hour prior to flying. Begin taking a decongestant, like Sudafed, one hour before the flight. Both of these medications can be purchased over-the-counter in a drug store.

As a general rule, flying with a sinus infection and a congested nose is not advised. Changes in cabin air pressure affect the air inside and outside of your head. As a result, clogged sinuses, which prevent you from equalizing pressure differences, can be excruciatingly painful.

Take a decongestant pill or use nasal spray before the flight. Get filtered earplugs which help to gradually equalize the air pressure against your middle ear.

MORE DETAILS

If you have sinus pressure during flights then you should bring along a decongestant spray (Oxymetazoline or Phenylephrine), found in the nasal aisle at the drug store, and use it approximately one hour before a flight of any duration.

If you start to notice this pressure building, you can try some of these strategies:
  1. Take an antihistamine if needed before your flight. ...
  2. Yawn or swallow during takeoff.
  3. Try chewing a piece of gum or candy during takeoff, if yawning and swallowing don't work for you.

Take a decongestant before your flight. Reducing congestion will help prevent ear barotrauma (airplane ear). Remember to swallow and yawn during plane takeoff and landing. This helps your eustachian tubes open.

MORE DETAILS

It's all due to pressure changes. As the plane starts to lose height, the pressure in the air around you changes. Until the pressure inside the tubes behind your eardrum adapts, the pressure inside and outside your ear is different.

MORE DETAILS

If your sinuses are congested, however, there will be an unbalanced amount of pressure. Not only can that be a very painful experience, but it can also increase nasal congestion, heighten allergies, worsen colds, and even trauma to the sinuses, if severe enough.

MORE DETAILS

When the plane changes elevation during descent and ascent the sinuses must equilibrate to match the air pressure in the cabin but when the sinuses and eustachian tubes are blocked equilibration can be an issue. The pain occurs because of the restriction of air flow causing pressure in our sinuses.

Treat congestion before your trip
If you're congested from allergies or an upper respiratory infection, it's important to do what you can to resolve the congestion before you fly. Common treatments for congestion include antihistamines, decongestants, and nasal steroid sprays.

Some studies suggest that the cabin pressure changes in the airplane, which are more pronounced during takeoff and landing, affects the head and sinuses in a way that triggers a headache. Another possible explanation for AHs is a fear of flying, which can cause stress and anxiety and subsequently trigger a headache.
