When You Take Too Much Sudafed, This Is What Happens

Sudafed is a common over-the-counter decongestant many of us turn to when we need to relieve sinus or nasal congestion. The medication can be bought without a prescription, but you likely won't find it on store shelves due to federal regulations. According to Sudafed, the medication is not sold at the pharmacy or service counter due to the main ingredient of pseudoephedrine, a decongestant known for shrinking blood vessels in the nasal cavity. Pseudoephedrine can be used to make methamphetamine, which is why federal regulations were put in place to keep it behind pharmacy counters.

Blood vessels in the nasal cavity swell when you experience nasal or sinus congestion. Sudafed works to shrink those blood vessels, and in turn, opens the nasal passages, allowing your sinuses to drain. While you may temporarily need more tissues, clearing out the nasal passages should help you breathe better.

According to Healthline, how much Sudafed you take is going to depend on the form of the medication and your age. Sudafed is available in many different forms, including tablets and liquids, and dosage will vary per person. For Sudafed Congestion, adults and children over the age of 12 can take 2 Sudafed tablets every 4-6 hours. For children ages 6 to 11, only 1 tablet is needed every 4-6 hours, while children under the age of 6 should not use Sudafed. Remember: it's always best to check with your doctor first before trying a new medication.
