5 Storage of Acetylsalicylic Acid Viatris
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.
This medicine is taken to reduce the risk of thrombus formation and consequently prevent:
This medicine 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
Consult your doctor or pharmacist before starting to take this medicine:
You should consult a doctor immediately if your symptoms worsen or if you experience serious or unexpected side effects, for example, unusual bleeding symptoms, severe skin reactions, or any other sign of severe allergy (see section "Possible side effects").
Inform your doctor if you have a planned surgical intervention (even a minor one, such as a tooth extraction), as acetylsalicylic acid is an anticoagulant, there may be an increased risk of bleeding.
You should be careful not to become dehydrated (you may feel thirsty and have a dry mouth) as the use of acetylsalicylic acid at the same time may cause deterioration of kidney function.
This medicine is not suitable as an anti-inflammatory, to relieve pain, or reduce fever.
If you are in any of the above cases, or if you are not sure, consult your doctor or pharmacist.
Children and adolescents
Acetylsalicylic acid may cause Reye's syndrome when administered to children. Reye's syndrome is a very rare disease that affects the brain and liver and can be life-threatening. For this reason, this medicine should not be given to children under 16 years of age, unless indicated by a doctor.
Other medicines andAcetylsalicylic Acid Viatris
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
The effect of treatment may be influenced if acetylsalicylic acid is taken at the same time as other medicines that are used to:
Metamizol (a substance to reduce pain and fever) may reduce the effect of acetylsalicylic acid on the reduction of platelet aggregation (blood cells that clump together and form a blockage), if administered together with acetylsalicylic acid. Therefore, this combination should be used with caution in patients who are taking it to protect the heart (cardioprotector).
TakingAcetylsalicylic Acid Viatriswithalcohol
Drinking alcohol may increase the risk of gastrointestinal bleeding and prolong bleeding time.

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
If you continue or start treatment with acetylsalicylic acid during pregnancy on the advice of your doctor, use acetylsalicylic acid according to your doctor's instructions and do not use a dose higher than recommended.
Pregnancy – last trimester
Do not take acetylsalicylic acid at doses above 100 mg per day if you are in the last 3 months of pregnancy, as it may harm the fetus or cause problems during delivery. It may cause kidney and heart problems in the fetus. It may affect your tendency to bleed and that of your baby and cause delivery to be delayed or prolonged more than expected.
If you take acetylsalicylic acid at low doses (up to 100 mg per day, inclusive), you will need strict obstetric monitoring as indicated by your doctor.
Pregnancy - first and second trimester
You should not take acetylsalicylic acid during the first 6 months of pregnancy unless it is absolutely necessary and your doctor advises you to do so. If you need treatment during this period, or while you are trying to become pregnant, you should use the lowest dose for the shortest possible time. If you take it for more than a few days from the 20th week of pregnancy, acetylsalicylic acid may cause kidney problems in the fetus that can 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 couple of days, your doctor may recommend additional monitoring.
