Patient Guide To Warf Therapy

What is Warf?

Warf (Warfarin) is used to prevent the formation of harmful blood clots in your body. Harmful blood clots can cause a stroke, heart attack, or other serious conditions.

What Should I Tell my Doctor Before Starting Warf?

Tell your doctor about all your health conditions, including if you:

  • Have bleeding problems
  • Have liver or kidney problems
  • Have high blood pressure
  • Have a heart problem called congestive heart failure
  • Have diabetes
  • Drink alcohol or have problems with alcohol abuse. Alcohol can affect your Warf dose and should be avoided.
  • Are pregnant or planning to become pregnant
  • Are breastfeeding. Warf may increase bleeding in your baby. Talk to your doctor about the best way to feed your baby.

What Should I Do while Taking Warf?

  • Take Warf exactly as prescribed by your doctor
  • Get a regular blood test, as instructed by your doctor, to check how fast your blood clots
  • Do not take or discontinue any other medicines or herbal products except on the advice of your doctor. This is because these can interact with Warf and affect the dose of Warf you need, or increase Warf side effects. Always keep a list of your medicines with you at all times to show your doctor
  • Avoid alcohol consumption
  • Do not take Warf during pregnancy and do not become pregnant while taking it. Use effective birth control if you can get pregnant.
  • Avoid any activity or sport that may result in traumatic injury.
  • If the prescribed dose of Warf is forgotten, inform your doctor immediately. Take the dose as soon as possible on the same day but do not take a double dose of Warf the next day to make up for missed doses. Call your doctor immediately if you take too much Warf.
  • The amount of vitamin K in food may affect therapy with Warf. Eat a normal, balanced diet maintaining a consistent amount of vitamin K. Avoid drastic changes in dietary habits, such as eating large amounts of green leafy vegetables.
  • Always tell your doctor and dentist that you are taking Warf. Tell your doctor about any planned surgeries, medical or dental procedures. Warf may have to be stopped for a short time or you may need your dose adjusted.
  • Call your doctor immediately if you fall or injure yourself, especially if you hit your head. Your doctor may need to check you.
