Understanding Sumatriptan Nasal Spray
Sumatriptan is a medication in the triptan class, commonly used for the acute treatment of migraine attacks and cluster headaches. It works by narrowing blood vessels around the brain, stopping pain signals, and blocking the release of substances that cause pain and nausea. The nasal spray formulation is often preferred by people who experience severe nausea or vomiting during an attack, as it bypasses the digestive system and provides rapid relief. Brand names include Imitrex® and Tosymra®. Each spray device contains a single, pre-measured amount and should never be tested or primed before use, as this will waste the medication.
How to Use Sumatriptan Nasal Spray: A Step-by-Step Guide
Following the correct technique is vital to ensure you receive the full amount of medication and maximize the spray's effectiveness. Always read the specific manufacturer's instructions for your prescribed brand, as there can be slight variations.
Step 1: Preparation
- Sit upright: Find a comfortable seated position to prevent the medication from dripping out prematurely.
- Clear your nostrils: Gently blow your nose to clear the nasal passages. This helps ensure the medication is properly absorbed.
- Wash your hands: Ensure your hands are clean before handling the medication.
- Prepare the device: Remove the nasal spray device from its sealed packaging only when you are ready to use it. Do not prime or test the spray, as each device contains only one measured amount.
Step 2: Administration
- Position the nozzle: Hold the sprayer upright with your thumb on the plunger and your first two fingers on either side of the nozzle.
- Close one nostril: Use your free hand to gently press one nostril closed.
- Insert the nozzle: Insert the tip of the nozzle into the open nostril about a half-inch, or as far as is comfortable. Tilt your head back slightly and aim the nozzle away from the center of your nose, towards the outside edge.
- Spray and inhale: While breathing in gently through your nose, press the plunger firmly and quickly to release the medication.
Step 3: Post-Administration
- Remove the device: Keep your head level and remove the nozzle from your nostril.
- Wait and breathe: Continue to breathe gently through your nose and out through your mouth for 10 to 20 seconds. Avoid sniffing deeply or blowing your nose immediately after, as this can cause the medication to drain from your nasal passages.
- Dispose of the device: Since each device contains only a single amount, dispose of it safely after use.
