How to use Pseudoephedrine ER
If you are taking the over-the-counter product to self-treat, read all directions on the product package before taking this medication. If you have any questions, ask your doctor or pharmacist. If your doctor has prescribed this medication, take it as directed.
Take this medication by mouth with or without food, usually every 12 or 24 hours, depending on the product or as directed by your doctor or the product package. Do not take more than 240 milligrams in a day. Dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this drug more often than directed. Do not take more of this medication than recommended for your age.
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.
Take the capsules or tablets with a glass of water. Swallow the capsules whole. Do not crush or chew the capsules or tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split the tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
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.
