Contents of the pack
This medicine contains acetylsalicylic acid, which at low doses belongs to a group of medicines called antiplatelet agents. Platelets are small blood cells that produce blood clotting and are involved in thrombosis. When a blood clot forms in an artery, it stops blood flow and cuts off oxygen supply. When this happens in the heart, it can cause a heart attack or angina; in the brain, it can cause a stroke.

Acetylsalicylic Acid RATIO is also used to prevent thrombus formation after certain types of heart surgery to widen or unblock blood vessels.
This medicine is not recommended for emergency cases. It can only be used as a preventive treatment.

Warnings and precautions
Before starting treatment with Acetylsalicylic Acid RATIO, inform your doctor:
You should consult a doctor immediately if your symptoms worsen or if you experience serious or unexpected side effects, e.g. unusual bleeding symptoms, severe skin reactions or any other sign of severe allergy (see section "Possible side effects").
Inform your doctor if you are planning to have surgery (even minor surgery, such as tooth extraction) as acetylsalicylic acid is an anticoagulant, and there may be an increased risk of bleeding.
Acetylsalicylic acid may cause Reye's syndrome when given to children. Reye's syndrome is a very rare disease that affects the brain and liver and can be life-threatening. For this reason, Acetylsalicylic Acid RATIO should not be given to children under 16 years of age, unless prescribed by a doctor.
You should be careful not to become dehydrated (you may feel thirsty and have a dry mouth) as using acetylsalicylic acid at the same time may cause kidney function to deteriorate.
This medicine is not suitable for relieving pain or reducing fever.
If you are in any of the above cases, or if you are not sure, consult your doctor or pharmacist.
Consult your doctor or pharmacist before starting to take Acetylsalicylic Acid RATIO 100 mg.

From the 20th week of pregnancy, if you take Acetylsalicylic Acid RATIO for more than a few days, it may cause kidney problems in your fetus, which may lead to low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for more than a few days, your doctor may recommend additional monitoring.
