Anticoagulation Clinic

An Anticoagulant stops your blood from clotting within the blood vessels.

The treatment is safe provided you follow the DO’s and DON’Ts listed on this page.

Always carry your yellow dosage letter with you and show it to your doctor or dentist when obtaining treatment. Show it to your Pharmacist when you are having a prescription dispensed and when purchasing medicines. As a pharmacist can advise you, it is in your own interest that you purchase all medicines from a Pharmacy. Also show it to anyone giving treatment which may result in bleeding.

Do's

DO carry this leaflet with you. Show it to the Doctor. Dentist or Pharmacist before you receive any medicine or treatment.

While taking anticoagulants you must have regular blood tests to check the dose of tablets you need. If you cannot attend tell the doctor or clinic and make another appointment.

PREGNANCY.

Oral anticoagulants taken in the early weeks of pregnancy carry a small risk of damaging the unborn child.

If you are a woman of childbearing age receiving anticoagulants you should not start a pregnancy without consulting your doctor, who will be able to decide whether or not you should continue your anticoagulation therapy.

If you find that your period is one week overdue, and you think you may e pregnant, you must see your doctor straight away.
