- Carotid artery stenting

Frequently Asked Questions about Aspirin
What is aspirin?
Aspirin is a common over-the-counter medication that belongs to a class of drugs known as nonsteroidal anti-inflammatory drugs (NSAIDs). It is primarily used as a pain reliever and fever reducer.
How does aspirin work?
Aspirin works by inhibiting the production of certain chemicals in the body called prostaglandins. These chemicals are involved in pain, inflammation, and fever. By reducing prostaglandin production, aspirin helps alleviate these symptoms.
What are the common uses of aspirin?
Aspirin is commonly used for pain relief, reducing fever, and relieving minor aches and pains. It is also prescribed by doctors to prevent blood clots, heart attacks, and strokes in certain individuals.
Is aspirin safe for everyone?
No, aspirin is not safe for everyone. It is not recommended for individuals with certain medical conditions or allergies, especially those with bleeding disorders, stomach ulcers, or aspirin allergies. It can also interact with other medications, so it's important to consult a healthcare professional before using it.
Can aspirin be given to children?
Aspirin should generally be avoided in children and teenagers with viral infections like the flu or chickenpox due to the risk of Reye's syndrome, a rare but serious condition. Acetaminophen or ibuprofen are usually preferred for pain and fever in this age group.
What are the potential side effects of aspirin?
Common side effects of aspirin can include stomach irritation, indigestion, and heartburn. In some cases, it may lead to more serious side effects such as gastrointestinal bleeding or allergic reactions. It's crucial to use aspirin as directed and seek medical attention if you experience severe side effects.
Can aspirin be taken with other medications?
Aspirin can interact with various medications, including blood thinners, anti-inflammatory drugs, and certain supplements. Always consult your healthcare provider or pharmacist before taking aspirin alongside other medications to avoid potential complications.
Can aspirin be used during pregnancy or while breastfeeding?
Pregnant and breastfeeding individuals should consult their healthcare provider before using aspirin. In some cases, it may be recommended, but it should be used under medical supervision due to potential risks to the fetus or infant.
Can aspirin be addictive?
Aspirin is not considered addictive because it does not produce the same effects as drugs that are known to be addictive. However, it should be used responsibly and according to the recommended dosage instructions.
What should I do if I accidentally take too much aspirin?
If you suspect an overdose or experience symptoms like ringing in the ears, dizziness, nausea, vomiting, or difficulty breathing after taking aspirin, seek immediate medical attention. An overdose of aspirin can be serious and even life-threatening.
