Active Ingredient

The active ingredient in Sudafed Syrup is pseudoephedrine. Pseudoephedrine is a decongestant that alleviates swelling and congestion in the nasal passages, sinuses, and eustachian tubes, which are the tubes that drain fluid from the inner ears.


Sudafed Syrup is available in 150 ml bottles. Each 5 ml dose contains 30 mg of pseudoephedrine. The syrup also includes other ingredients such as sugar, methyl paraben, sodium benzoate, ponceau 4R, and raspberry essence.


Pseudoephedrine, the active ingredient, exhibits both direct and indirect sympathomimetic activity, making it an effective upper respiratory decongestant. Compared to ephedrine, it is less effective in raising systolic blood pressure and inducing tachycardia. Pseudoephedrine reaches its peak decongestant effect within 30 minutes and lasts for about 4 hours.


Sudafed Syrup is indicated for symptomatic relief in conditions such as allergic rhinitis, vasomotor rhinitis, colds, flu, and the common cold. It helps to open the nasal passages and reduce nasal discharge, providing relief from symptoms.


Sudafed Syrup is contraindicated in individuals with hypersensitivity to pseudoephedrine or any of the other components of the medication. It should not be used in patients with severe hypertension or severe coronary artery disease. Additionally, it is contraindicated for patients who have taken monoamine oxidase inhibitors (MAOIs) within the previous two weeks.

Side Effects

Sudafed Syrup can cause a range of side effects, which can be categorized into common and less common side effects.

Category Side Effect
Common Side Effects Insomnia, headache, nervousness, restlessness, excitability (especially in children), dizziness, nausea
Less Common Side Effects Fast or uneven heart rate, severe dizziness or anxiety, severe headache, mood changes, fever

Please note that this is not an exhaustive list of side effects. Always consult your healthcare provider for personalized medical advice.

Availability and Prescription Requirements

Sudafed Syrup is generally available as an over-the-counter (OTC) medication. However, it is typically kept behind the pharmacy counter, and a valid form of identification is required for purchase. There are also limits on how much can be bought each month without a prescription. In certain locations, such as Oregon and Mississippi, as well as some cities in Missouri and Tennessee, a prescription is required.

Use During Pregnancy and Breastfeeding


Sudafed Syrup contains pseudoephedrine, which is generally considered safe for use during pregnancy. However, some studies have shown a slightly higher risk of birth defects when used during the first trimester. Therefore, the American College of Obstetricians and Gynecologists (ACOG) recommends avoiding pseudoephedrine in the first trimester. If needed later in pregnancy, it is best to consult a healthcare provider.


Pseudoephedrine passes into breast milk. While the American Academy of Pediatrics considers it likely safe, there is a potential for reduced milk production. One study showed a 24% decrease in milk production over a 24-hour period. Therefore, breastfeeding mothers should monitor their milk supply and consult a healthcare provider before using Sudafed.

Use in Children

Sudafed Syrup is generally safe for children over the age of four years, helping to relieve nasal congestion from colds or allergies. However, it should not be used in children younger than four due to the risk of accidental overdose and serious side effects. Children with certain health conditions should avoid Sudafed.

Use in Older Adults

Older adults can use Sudafed Syrup but may be more sensitive to its side effects, which include dizziness, difficulty urinating, fast or irregular heartbeat, trouble sleeping, confusion, or mental/mood changes. They should consult a healthcare provider before starting any new medication.

Sudafed Syrup, containing pseudoephedrine, can interact with several other medications. Notable interactions include:

The truth is that when we’re sick, or worried about getting sick, the internet won’t help.

According to Wikipedia, cyberchondria is a mental disorder consisting in the desire to independently make a diagnosis based on the symptoms of diseases described on Internet sites.

Why you can't look for symptoms on the Internet

If diagnoses could be made simply from a textbook or an article on a website, we would all be doctors and treat ourselves. Nothing can replace the experience and knowledge of specially trained people. As in any field, in medicine there are unscrupulous specialists, differences of opinion, inaccurate diagnoses and incorrect test results.
