Seasonal Allergy Medications & Your INR

By: Alere Staff

Allergies from flower, tree and grass pollen affect millions of people of all ages. Watery eyes, nasal congestion and feeling crummy are what you may feel sometimes or all the time during allergy season.

Spring and early summer are the worst time for allergy symptoms. There are simple things you can do to reduce the severity of your allergy symptoms.

  • Stay inside during windy days
  • Don’t dry your clothes outside in the spring and early summer
  • Wash your clothes, shower and shampoo your hair after returning from outdoors
  • Keep your windows closed during high pollen count days
  • Look into hiring individuals to mow your lawn and weed your garden

There are many over-the-counter medications and natural remedies to help reduce the symptoms of runny noses and constant sneezing. If you see your doctor about your allergies, make sure you tell them if you are taking warfarin. Some medicines may interact with warfarin and require an additional INR blood test.

Many people are turning to natural medicines to manage allergy symptoms. This keeps prescription drug costs down, however; you may not know all the ingredients that go into the natural supplement or how much to take for your age and body size. Many natural remedies contain organic plant products, which may also interact with warfarin.

Before starting or stopping any new products, share your plans with your doctor. Increasing testing frequency is recommended when starting or stopping any new medication or dietary supplement including vitamins. Home INR monitoring may help improve your control of warfarin with more frequent testing. Weekly testing, typically performed by patient self-testing, is a valuable tool for detecting rises and falls in INR values and enable you to work with your doctor to make any adjustments to diet or medication dosing.1 Go to the Getting Started page or call Alere at 1.800.504.4032 for more information about testing your INR at home.
