For years, the drug phenylephrine has been a preferred selection for relieving nasal congestion, nonetheless, the US Food and Drug Administration (FDA) Considering removal. Oral phenylephrine medications from pharmacy shelves. Recent FDA findings Suggest that it lacks effectiveness.
Phenylephrine became widely used as a safer alternative to pseudoephedrine in cold and flu products. Although pseudoephedrine is effective, there are some risks of abuse – its use with criminals to make methamphetamine. However, recent studies query whether phenylephrine is effective when taken orally.
It is now being debated within the UK and other countries. Ethics Continue to sell it. So should Britain take motion?
There are pros and cons to removing phenylephrine from UK shelves. On the one hand, continuing to sell potentially ineffective products can undermine public confidence in over-the-counter (OTC) medications. Consumers expect these products to be secure and effective — not only secure — so evidence against phenylephrine can undermine that trust.
As studies proceed to query the effectiveness of oral phenylephrine, some experts imagine it could be time to reconsider its place within the UK. Fortunately, there are alternatives. As mentioned, pseudoephedrine is effective as a nasal decongestant, however it comes with purchasing restrictions. Phenylephrine nasal sprays may additionally provide more direct relief.
Phenylephrine and pseudoephedrine each relieve nasal congestion by constricting the blood vessels within the nasal passages, which reduces swelling and makes respiration easier. However, their effectiveness is determined by how well the drug reaches these goal tissues.
Pseudoephedrine is usually considered a more practical option, entering the bloodstream and reaching the nasal tissues, acting directly on the blood vessels to scale back congestion. Phenylephrine is less effective when taken orally, nonetheless, since it is broken down considerably before reaching the nasal tissues in sufficient amounts.
When swallowed, phenylephrine is rapidly broken down by the liver and intestines, a process often known as “first-pass metabolism,” which significantly reduces the quantity reaching the blood and nasal tissues. .
Because little phenylephrine escapes this process, it doesn't effectively reduce swelling within the nasal blood vessels, providing limited relief of congestion. Research from Several studies Little evidence shows that oral phenylephrine effectively relieves nasal congestion. The results suggest that it could not work higher than a placebo.

Phenylephrine works best as a nasal spray, acting totally on the liner of the nose with minimal absorption into the bloodstream. But long-term use of decongestant sprays can result in “rebound congestion,” a condition where the nasal passages change into more congested because the spray wears off, often with worsening symptoms over time.
Medicines cause the blood vessels within the nasal passages to change into less responsive over time. This can create a cycle of dependency and congestion. To avoid this, these sprays are really useful for short-term use only.
Although some products recommend limiting use to seven days, many health experts recommend keeping it to a few days to scale back the chance of rebound congestion.
Still available within the UK – for now
In the UK, the Medicines and Healthcare Products Regulatory Agency (MHRA) What is the statement? that no latest safety concerns have been identified with phenylephrine. However, the agency continues to watch its safety and effectiveness.
Although it's unclear whether the MHRA will undertake a proper review, such a move can be in step with evidence-based standards and help protect consumer confidence.
With the effectiveness of phenylephrine now in query, users will want to consider other options. For short-term use, alternatives akin to pseudoephedrine and nasal sprays can provide reliable relief.
