A.A.S. 100 mg is indicated to prevent the formation of blood clots and reduce the risk of blockage of your arteries, as:

• you have previously experienced a heart attack or angina pectoris.
• you have experienced a transient or permanent ischemic stroke.
• you have undergone a surgical intervention, such as coronary angioplasty or coronary bypass surgery.

Do not take A.A.S. 100 mg:

• If you are allergic to acetylsalicylic acid or any of the other components of this medication (listed in section 6).
• If you have had mastocytosis (usually characterized by urticaria) as severe hypersensitivity reactions (exaggerated and severe allergic reactions with flushing, hypotension, tachycardia, and vomiting) may occur.
• If you have or have had gastric ulcers, duodenal ulcers, or repeated gastric discomfort.
• If you have had allergic reactions of the asthmatic type (difficulty breathing, choking, bronchospasm, and in some cases coughing or wheezing) when taking medications to reduce inflammation, acetylsalicylic acid, other analgesics, as well as when taking tartrazine dye.
• If you have or have had asthma or nasal polyps associated with asthma that are produced or increased by acetylsalicylic acid, rhinitis, or urticaria.
• If you have hemophilia or other bleeding disorders that predispose you to internal bleeding, have any other bleeding disease or risk of bleeding.
• If you are being treated with medications to promote blood circulation (oral anticoagulants) (see “Taking A.A.S. 100 mg with other medications”).
• If you are being treated with methotrexate at doses above 20 mg/week (see “Taking A.A.S. 100 mg with other medications”).
• If you have severe liver failure.
• If you have severe kidney failure.
• If you have severe and uncontrolled heart failure.
• If you are under 16 years old, unless a doctor's explicit indication, as the use of acetylsalicylic acid has been associated with Reye's syndrome, a rare but potentially fatal disease.
• If you are in your third trimester of pregnancy (more than 24 weeks of gestation), at doses above 100 mg/day (see “Pregnancy, breastfeeding, and fertility”).

Warnings and precautions

Consult your doctor or pharmacist before starting to take A.A.S. 100 mg if you are in any of the following cases:

• You have any kidney, heart, or liver disease.
• You have mild or moderate liver failure (in case of severe liver failure, it is contraindicated, see “Do not take A.A.S. 100 mg”).
• You have alterations in blood coagulation or are being treated with anticoagulants.
• You have gout. Acetylsalicylic acid modifies serum uric acid at analgesic doses.
• You have uterine bleeding outside of menstruation or metrorrhagia or menorragia (prolonged and increased menstrual bleeding).
• You are to undergo surgical intervention, including dental surgery. In that case, you should inform your doctor or dentist.
• If you have recently been vaccinated.
• If you have rhinitis and/or urticaria.
• At high doses (anti-inflammatory doses), consult your doctor if you experience buzzing or noise in your ears, reduced hearing, or dizziness.
• If you have a deficiency of glucose-6-phosphate dehydrogenase due to the risk of hemolysis (see “Possible adverse effects”).
• Avoid concurrent treatment with levotiroxine (for hypothyroidism) and salicylates (see “Taking A.A.S. 100 mg with other medications”).
• If you are taking anti-inflammatory medications or other types of medications, as certain medications may interact with A.A.S. 100 mg and produce unwanted effects (see “Taking A.A.S. 100 mg with other medications”).
• You have hypertension.
• In treatments with doses ≥ 500 mg/day, female fertility may be altered due to an effect on ovulation, which is reversible upon withdrawal of treatment.
• Do not take alcohol as it increases the gastrointestinal adverse effects of acetylsalicylic acid, and is a trigger for chronic irritation caused by acetylsalicylic acid (see “Taking A.A.S. 100 mg with food, beverages, and alcohol”).
• In patients being treated with nicorandil and acetylsalicylic acid, there is a higher risk of severe complications such as gastrointestinal ulcers, perforation, and bleeding (see “Taking A.A.S. 100 mg with other medications”).
• History of gastric ulcers, gastrointestinal bleeding, or gastritis. Avoid taking it together with other medications that may increase the risk of bleeding. Consult your doctor.
• Patients with asthma: the appearance of asthma attacks may be related to an allergy to non-steroidal anti-inflammatory drugs or acetylsalicylic acid. In this case, this medication is contraindicated.

• Reye's syndrome, a rare but potentially fatal disease, has been observed in children and adolescents with viral infections (especially varicella and influenza) and who are taking acetylsalicylic acid. Therefore, acetylsalicylic acid should only be administered to these children and adolescents under medical recommendation, when other measures have failed. In case of persistent vomiting, loss of consciousness, or abnormal behavior, treatment with acetylsalicylic acid should be interrupted.
• This medication contains acetylsalicylic acid. Other medications also contain it, do not take them together to avoid exceeding the recommended daily dose.
• The regular use of analgesics, especially when combined with analgesics, can cause persistent renal damage with a risk of renal failure.
• This medication is not recommended for use during breastfeeding (see “Pregnancy, breastfeeding, and fertility”).

Consult your doctor, even if any of the circumstances mentioned above have occurred at any time.

Taking A.A.S. 100 mg with other medications
