Pseudoephedrine is a non-prescription (over-the-counter) medication that helps treat a stuffy nose. It belongs to a category of medications known as nasal decongestants. It narrows the blood vessels in the nose that bring on congestion when symptoms develop.
This medicine is available in the form of tablets as well as extended release tablets. Standard tablets are taken 4-6 times daily as needed. Extended release tablets, on the other hand, are taken once or twice daily with a full glass of water.
Don’t chew, split, or break the extended release tablets. Make sure to swallow them whole.
Pseudoephedrine is also available as a solution (oral suspension) and chewable tablets for children’s dosage.
Pseudoephedrine can cause side effects like a pounding, fast heartbeat, ringing in ears, and dizziness. Don’t use heavy machines or drive until you understand how this medicine affects you.
Alongside its useful effects, Pseudoephedrine can cause various adverse effects. While not all of the effects below can occur, some of them may require medical attention.

Pseudoephedrine comes together with other medications or alone. Ask your pharmacist or doctor for advice about which medication is suitable for your symptoms.
