1. What is Aspirin and what is it used for

The active ingredient of this medication, acetylsalicylic acid, belongs to a group of medications known as non-steroidal anti-inflammatory drugs (NSAIDs). It relieves pain and reduces fever.

This medication is used for the symptomatic relief of occasional mild or moderate pain, such as headaches, dental pain, menstrual pain, muscle pain (cramps) or back pain (lumbago) and febrile states in adults and adolescents over 16 years of age.

You should consult a doctor if your symptoms worsen or do not improve after 5 days for pain or 3 days for fever.

2. What you need to know before taking Aspirin

• you are allergic or have had an allergic reaction to acetylsalicylic acid or any other component of this medication (listed in section 6),
• you have stomach ulcers, intestinal ulcers, or recurring gastric discomfort,
• you have had allergic reactions of an asthmatic type (difficulty breathing, shortness of breath, bronchospasm, and in some cases coughing or wheezing when breathing) when taking anti-inflammatory medications, acetylsalicylic acid, other analgesics, as well as the tartrazine dye,
• you have asthma,
• you have nasal polyps associated with asthma that are produced or increased by acetylsalicylic acid,
• you have hemophilia or other blood coagulation problems,
• you are being treated with oral anticoagulant medications,
• you have kidney and/or liver disease (renal and/or hepatic insufficiency),

• you are in your third trimester of pregnancy.

Be careful with Aspirin

• if you have high blood pressure, or have reduced kidney, heart, or liver function, or have blood coagulation disorders,
• if you have had stomach or intestinal ulcers,
• if you are being treated with anticoagulants, you should consult your doctor before taking this medication,
• if you are taking anti-inflammatory medications or other types of medications, as certain medications can interact with Aspirin 500 mg effervescent tablets and produce undesirable effects (see "Use of other medications"),
• if you are allergic to other anti-inflammatory or anti-rheumatic medications,
• if you have a glucose-6-phosphate dehydrogenase deficiency,
• if you have or have had rhinitis or urticaria,

• if you have recently undergone or are scheduled to undergo surgery in the next 7 days, including dental surgery,

Other medications and Aspirin

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

This is especially important in the case of:

• other analgesics or non-steroidal anti-inflammatory medications (medications used to treat pain and/or muscle inflammation),

• oral antidiabetics (medications to lower blood sugar levels),
• barbiturates (medications used to treat seizures),
• beta blockers (medications to control high blood pressure),
• cimetidine and ranitidine (used for stomach acidity),
• medications used to prevent transplant rejection (cyclosporine and tacrolimus),
• corticosteroids, as they may increase the risk of gastrointestinal bleeding,
• digoxin (medication for the heart),
• high blood pressure (diuretics and ACE inhibitors),
• phenytoin and valproic acid (antiepileptics),
• interferon alpha (used to treat certain viral and tumor infections),
• lithium (used in certain psychiatric illnesses),
• cancer or rheumatoid arthritis (methotrexate),
• medications used to treat gout (probenecid),
• vancomycin (antibiotic used for infections),
