If you are using the suspension (liquid), shake the bottle well before each dose. Use a medication-measuring device or spoon to carefully measure the dose. Do not use a household spoon because you may not get the correct dose.

Swallow the sustained-release tablets/capsules whole with a glass of water. Do not crush, chew, or split them. Doing so can destroy the long action of the drug and may increase side effects.

There are many brands and forms of pseudoephedrine available. Read the dosing instructions carefully for each product because the amount of pseudoephedrine may be different between products. Do not take more pseudoephedrine than recommended.

Caffeine can increase the side effects of this medication. Avoid drinking large amounts of beverages containing caffeine (coffee, tea, colas), eating large amounts of chocolate, or taking nonprescription products that contain caffeine.

If your symptoms do not improve after 7 days, if they worsen or return, if you develop fever, rash, or a persistent headache, or if you think you may have a serious medical problem, seek immediate medical attention.
