From the Guidelines
For congestion from a viral illness, pseudoephedrine (Sudafed) is generally the most effective over-the-counter decongestant, as supported by the most recent and highest quality study 1.
Key Points to Consider
- Take 30-60mg every 4-6 hours as needed, not exceeding 240mg in 24 hours.
- The 12-hour extended-release formulation (120mg) can be taken twice daily.
- Pseudoephedrine works by constricting blood vessels in the nasal passages, reducing swelling and mucus production.
- For those who can't take pseudoephedrine due to high blood pressure or heart conditions, phenylephrine (like Sudafed PE) is an alternative, though it's less effective, as noted in 1 and 1.
Additional Relief Measures
- Nasal saline sprays and humidifiers can provide additional relief.
- Stay hydrated and consider taking acetaminophen or ibuprofen for associated symptoms like fever or pain.
- If you're taking other medications, check for interactions, and avoid pseudoephedrine if you have hypertension, heart disease, glaucoma, or hyperthyroidism, as cautioned in 1 and 1.
When to Consult a Healthcare Provider
- If symptoms persist beyond 7-10 days or worsen significantly, consult a healthcare provider.
- It's also important to note that while pseudoephedrine is effective, its use should be monitored, especially in patients with certain conditions, as discussed in 1 and 1.

From the Research
Decongestants for Viral Illness
- Decongestants are effective in reducing nasal congestion associated with viral illnesses, such as the common cold 3, 4.
- Phenylpropanolamine, pseudoephedrine, and phenylephrine are common decongestants, but their efficacy varies, with pseudoephedrine being a widely used and effective option 3, 4.
- Pseudoephedrine has been shown to be safe and effective in treating nasal congestion associated with upper respiratory tract infections (URTI) 4.
Combination Therapies
- Combination therapies, such as desloratadine and pseudoephedrine, can provide comprehensive treatment for allergic rhinitis and nasal congestion 5.
- These combinations can improve symptoms of nasal congestion and quality of life, with significant improvements observed by day 2 of treatment 5.
Safety and Regulations
- Ephedrine and pseudoephedrine should not be used in patients under the age of 15 due to potential severe cardiovascular and neurological adverse events 6.
- Distribution of these medications should be regulated, and over-the-counter sales banned, to minimize risks 6.
- Fixed-dose combinations, such as paracetamol, chlorphenamine, and phenylephrine, can be safe and effective in treating symptoms of the common cold, but their use should be carefully evaluated 7.
