Do oral decongestants have side effects?

Oral decongestants can help relieve environmental allergies, but like all drugs, they can have side effects. Oral decongestants can make you lightheaded, irritable, or anxious, increase your heart rate or cause it to beat irregularly, and give you headaches, insomnia, tremors, or increased blood pressure. If you have certain conditions or take certain medications, you could suffer serious side effects if you take oral decongestants. Check with your doctor to see if these medications are right for you.
