Plavix should be cleared from your system in about 33 hours.
After a single, oral dose of 75 mg, Plavix (clopidogrel) has a half-life of approximately 6 hours. It takes 5.5 x half-life of a medicine for it to be out of one's system, therefore Plavix should be eliminated from your system in 5.5 x 6 = 33 hours.
However other factors to consider include:
1. How much and how often you have taken the drug.
2. Your metabolic rate – a slower metabolism will increase the time a drug remains in your system.
3. Your age and health – older age and poor health will generally increase the time the drug stays in your system.
4. Body mass – generally the bigger you are the longer a drug will remain in your system.
The recommended daily dose of Plavix is 75 milligrams once a day. To give people with unstable angina an extra boost, their first dose is usually increased to 300 milligrams. Anything more than this is too much.
