Brief Answer:
mostly eliminated in 15 to 40 hours

Detailed Answer:
HI, thanks for using healthcare magic

Zephrex D contains pseudoephedrine , a decongestant, which can increase blood pressure.

The half life of a medication is the time it takes for the amount of drug in the body to decrease by half. It can take 3 to 5 half lives approximately for a medication to be mostly eliminated.

The half life of pseudoephedrine is 5 to 8 hours. This means that it would take 15 to 40 hours, for this medication to be mostly eliminated from the body.

During this time the levels would be steadily declining.

I hope this helps, feel free to ask any other questions
