A.A.S. 100 mg TABLETS

2. What you need to know before you take A.A.S. 100 mg

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

• If you are allergic to acetylsalicylic acid or any of the other ingredients of this medicine (listed in section 6).
• If you have suffered from mastocytosis (usually characterized by hives) since severe hypersensitivity reactions (exaggerated and severe allergic reaction with flushing, hypotension, tachycardia, and vomiting) may occur.
• If you have or have had stomach ulcers, duodenal ulcers, or recurring stomach discomfort.
• If you have had allergic reactions of an asthmatic type (difficulty breathing, shortness of breath, bronchospasm, and in some cases cough or wheezing when breathing) when taking medications to reduce inflammation, acetylsalicylic acid, other pain relievers, 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 hives.
• If you have hemophilia or other blood coagulation problems that predispose you to internal bleeding, have any other bleeding disorder, 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 medicines").
• If you are being treated with methotrexate used at doses higher than 20 mg/week (see "Taking A.A.S. 100 mg with other medicines").
• If you have severe liver failure.
• If you have severe kidney failure.
• If you have severe uncontrolled heart failure.
• If you are under 16 years old, unless explicitly indicated by a doctor, since the use of acetylsalicylic acid has been related to Reye's syndrome, a rare but serious disease.
• If you are in your third trimester of pregnancy (more than 24 weeks of gestation), at doses higher than 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 these cases:

• You have kidney, heart, or liver disease (in case of severe kidney failure, it is contraindicated, see "Do not take A.A.S. 100 mg").
• 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 blood coagulation disorders or are being treated with anticoagulants.
• You have gout. Acetylsalicylic acid modifies serum uric acid at analgesic doses.
• You have uterine bleeding outside the menstrual period or metrorrhagia or menorrhagia (prolonged and increased menstrual bleeding).
• You need to undergo surgical intervention, including dental surgery. In that case, you should inform your doctor or dentist.
• If you have been recently vaccinated.
• If you have rhinitis and/or hives.
• At high doses (anti-inflammatory doses), consult your doctor if you experience ringing or noise in the ears, reduced hearing, or dizziness.
• If you have a glucose-6-phosphate dehydrogenase deficiency due to the risk of hemolysis (see "Possible side effects").
• Concomitant treatment with levotyroxine (for hypothyroidism) and salicylates should be avoided (see "Taking A.A.S. 100 mg with other medicines").
• If you are taking anti-inflammatory drugs or other types of medications, as certain medications can interact with A.A.S. 100 mg and produce unwanted effects (see "Taking A.A.S. 100 mg with other medicines").
• You have high blood pressure.
• In treatments with doses ≥ 500 mg/day, female fertility may be altered due to an effect on ovulation, being reversible with treatment withdrawal.
• You should not drink alcohol because it increases the risk of gastrointestinal damage when taken with acetylsalicylic acid, and it is a triggering factor for the chronic irritation produced by acetylsalicylic acid (see "Warnings and precautions").
• In patients treated with nicorandil and acetylsalicylic acid, there is a higher risk of serious complications such as gastrointestinal ulcers, perforation, and bleeding (see "Taking A.A.S. 100 mg with other medicines").
• History of gastroduodenal ulcers, gastrointestinal bleeding, or gastritis. Avoid taking concomitantly with other medications that may increase the risk of bleeding. Consult your doctor.
• Patient with asthma: the onset 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 very rare but potentially fatal disease, has been observed in children and adolescents with viral infections (especially chickenpox and flu) and who are taking acetylsalicylic acid. Consequently, acetylsalicylic acid should be administered to these children and adolescents only 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 discontinued.
• This medication contains acetylsalicylic acid. Other medications also contain it; do not take them at the same time to avoid exceeding the recommended daily dose.
• Regular use of pain relievers, especially when combining pain relievers, can cause persistent kidney damage with a risk of kidney failure.
• It is not recommended to use this medication during breastfeeding (see "Pregnancy, breastfeeding, and fertility").

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

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

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medications, including those obtained without a prescription, homeopathic, herbal, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of any of them.

• Anticoagulants (medications used to thin the blood and prevent the formation of clots), thrombolytics (to dissolve clots), antiplatelet agents, and other medications associated with a risk of bleeding.
• Medications that lower blood sugar levels (oral antidiabetics and insulin).
• Barbiturates (medications used to combat sleep disorders, such as sedatives and anticonvulsants).
• Corticosteroids (except hydrocortisone), as they may increase the risk of gastrointestinal bleeding.
• Cimetidine and ranitidine (used to reduce stomach acidity).
• Digoxin (medication used to treat heart conditions).
• Phenytoin and valproic acid (antiepileptic drugs).
• Lithium and serotonin receptor inhibitors (used in the treatment of depression).
