Aspirin starts to relieve pain within 20 minutes to 30 minutes of taking it.
The exact time that it takes for the aspirin to work to relieve pain also depends on the form of aspirin and how it's taken.
Powder and Effervescent tablet aspirin are the fastest acting forms of aspirin and the dissolvable powder packs of aspirin can start showing and providing you noticeable pain relief in around 10 minutes to 20 minutes.
Standard swallowable aspirin tablets or pills often take 20 to 30 minutes to kick in and start relieving pain.
Standard swallowable aspirin tablets or pills often reach their peak pain relieving effects within 1 hour to 2 hours.
Chewable aspirin tablets, which are non coated speeds up the absorption of the aspirin and allows the aspirin medication to enter your bloodstream much faster than swallowing it whole.
And for enteric coated aspirin tablets, these types of aspirin tablets have a special coating that is designed to protect your stomach.
So the enteric coated aspirin tablets dissolve much slower, which means that they will take a significantly longer time to relieve any acute pain.
Aspirin requires time to work as aspirin works by blocking your body's production of prostaglandins, which are the chemicals that trigger, pain, fever and inflammation in the body.
To treat pain or fever with aspirin, adults often take a higher dose of 300 mg to 1,000 mg of aspirin every 4 hours to 6 hours.
