Coumadin

A common starting dosage of Coumadin tablets for adults is 2 to 5 milligrams per day. Individualized daily dosage adjustments are based on the results of tests that determine the amount of time it takes for the blood clotting process to begin.

A maintenance dose of 2 to 10 milligrams per day is satisfactory for most people. The duration of treatment will be determined by your physician.

CHILDREN

Although Coumadin has been widely used in children below the age of 18, its safety and effectiveness for this purpose have not been formally established.

OLDER ADULTS

Low starting and maintenance doses are recommended for older people, as the drug tends to have a greater effect.

Overdosage

Signs and symptoms of Coumadin overdose reflect abnormal bleeding.

• Symptoms of abnormal bleeding include:
  Blood in stools or urine, excessive menstrual bleeding, black stools, reddish or purplish spots on skin, excessive bruising, persistent bleeding from superficial injuries

If you suspect an overdose, seek emergency medical treatment immediately.
