Why is this medication prescribed?

Deconex is often prescribed to relieve nasal congestion caused by various conditions such as the common cold, allergies, hay fever, or sinusitis. It contains active ingredients like phenylephrine or oxymetazoline, which work by constricting blood vessels in the nasal passages. This constriction reduces swelling and congestion, making it easier to breathe through the nose.

How should this medicine be used?

Deconex is typically available as nasal drops or nasal spray and should be used as directed by a healthcare professional or as indicated on the product label. Here’s a general guideline for using Deconex nasal drops or spray:

  • Wash your hands thoroughly with soap and water before handling the medication.
  • Remove the protective cap from the bottle.
  • If using a nasal spray, shake the bottle gently before each use.
  • Tilt your head back slightly or lie down on your back.
  • Insert the nasal applicator into one nostril while keeping the other nostril closed with your finger.
  • Press down on the pump or squeeze the bottle to release the prescribed number of drops or sprays into the nostril.
  • Breathe in gently through your nose while administering the medication.
  • Repeat the process for the other nostril if instructed to do so.
  • After using the medication, avoid blowing your nose immediately to allow the medication to remain in the nasal passages.

It’s crucial to follow the dosage instructions provided by your healthcare provider or the product label. Do not exceed the recommended dosage or frequency of use, as overuse can lead to rebound congestion or other side effects. If you have any questions or concerns about how to use Deconex, consult your healthcare provider for personalized advice.
