How should I take pseudoephedrine?

Do not take pseudoephedrine for longer than 7 days in a row. Talk with your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache, cough, or skin rash.
If you need surgery, tell the surgeon ahead of time that you are using pseudoephedrine. You may need to stop using the medicine for a short time.
