We spend loads on over-the-counter chilly and flu treatments — greater than £250 million a yr within the UK alone — to deal with the distress of blocked noses, tickly coughs and sore throats.
However may we be losing our cash?
A ruling earlier this month by a panel of particular advisers to the Meals and Drug Administration (FDA) — which oversees using medicines within the U.S. — has despatched shockwaves by means of the multi-million-pound chilly and flu product trade on each side of the Atlantic.
After reviewing years of knowledge on the effectiveness of well-liked manufacturers, the 16-strong panel dominated that phenylephrine — a key ingredient in most sorts of oral decongestants bought over-the-counter within the UK — is not any higher than a placebo on the subject of clearing stuffy noses and bettering respiratory.
They concluded that taking the drug orally, which is the commonest strategy, means not sufficient reaches the nostril to have a significant impact, as a lot of it will get ‘misplaced’ on the journey from the abdomen to the nostril.

In nasal spray kind, the reviewers mentioned that phenylephrine does appear to work, as virtually all of the lively drugs lands the place it’s wanted.
Phenylephrine eases nasal congestion by briefly shrinking the tiny blood vessels that sit contained in the nostrils, making extra space for air to go by means of.
However as one member of the panel instructed reporters, the proof was ‘fairly compelling that this remedy shouldn’t be efficient’ when taken orally.
In the meanwhile phenylephrine is designated by the FDA to be ‘efficient’, however this may occasionally now must be revoked. If the FDA agrees with the advisory panel’s ruling (its determination is predicted inside months), it could ban its use in tablets and capsules, probably forcing producers to tug their merchandise from pharmacy cabinets.
Following the FDA panel’s announcement, the UK medicine watchdog, the Medicines and Healthcare merchandise Regulatory Authority (MHRA), mentioned customers can ‘proceed to make use of merchandise made with phenylephrine as directed’.
However some specialists are predicting {that a} ban within the U.S. will result in grocery store cabinets right here additionally being stripped of oral medicines that comprise phenylephrine (in addition to chilly and flu treatments, it’s present in some tablets for sinusitis and allergy- associated stuffiness).
‘Nearly all oral decongestant merchandise on sale right here comprise phenylephrine,’ says Professor Ron Eccles, who ran the Widespread Chilly Centre at Cardiff College earlier than retiring from the college in 2017. ‘If the FDA ban it — and I feel it would — it may have an enormous impact on the UK, the place gross sales of those merchandise are price tons of of thousands and thousands of kilos.’
However producers are usually not simply having to contemplate reformulating or eradicating their merchandise; some are actually dealing with attainable authorized motion within the U.S. on the premise of the advisory panel ruling.
A category-action lawsuit claims the businesses knew their decongestant merchandise didn’t work as marketed and induced customers to waste cash on ineffective merchandise — and, given the shortage of profit, unnecessarily uncovered them to the potential side-effects of the drug, which may embody complications, insomnia and (at excessive doses) hypertension.
Adam Levitt, one of many U.S. legal professionals dealing with the case, instructed reporters earlier this month: ‘There’s a significant issue when a decongestant does not ‘decongest’.
In nasal spray kind, the reviewers mentioned that phenylephrine does appear to work, as virtually all of the lively drugs lands the place it’s wanted (file picture)
‘It is a prime instance of how the pharmaceutical trade makes billions by knowingly promoting questionable merchandise to customers who’re affected by particular illnesses.’
Professor Eccles says producers of chilly and flu treatments made with phenylephrine are actually frantically on the lookout for different substances in anticipation of future UK restrictions on its use in oral formulations.
‘A few of them have been asking me what they will use as a alternative and I am having to inform them there is not something appropriate, now or within the analysis pipeline,’ he says.
Phenylephrine was developed practically a century in the past and has develop into the mainstay of top-selling oral manufacturers similar to Lemsip, Boots Max Power Sinus Strain & Ache Reduction Capsules and Superdrug Max Congestion Reduction Capsules.
Its use boomed after merchandise made with a simpler rival ingredient — pseudoephedrine — had been faraway from cabinets within the UK in 2008 to forestall criminals turning it into the unlawful drug crystal meth.
Phenylephrine can’t be became crystal meth.
As soon as pseudoephedrine medicines had been made pharmacy-only (the place it’s important to ask the pharmacist for it earlier than you should purchase it), use of phenylephrine in over-the-counter manufacturers soared. But when phenylephrine is ineffective taken orally, how did it come to be licensed for one of these use?
Among the specialists who’ve lobbied the FDA to tug it from the market had gone by means of the info used for the drug’s approval within the Seventies and located a number of the info submitted had not been peer-reviewed (the place specialists within the area scrutinise it first).
Moreover, when the info was run by means of fashionable software program to analyse its accuracy, the outcomes urged phenylephrine was no higher than a placebo.
Considerations concerning the drug had been first put to the U.S. drug authorities 30 years in the past. However when the FDA reviewed the proof in 2005, it judged the drug to be ‘weakly lively’ and, due to this fact, nonetheless worthy of approval.
This is not the primary time questions have been raised about over-the-counter cough and chilly treatments. In 2014, a significant assessment by the extremely revered Cochrane organisation — a UK physique which scrutinises the proof for the effectiveness of medicines — discovered there was ‘no good proof for or towards’ using over-the-counter cough medicines bought right here.
HOW EXPERTS TREAT THEMSELVES
Professor Ron Eccles, former director of the Widespread Chilly Analysis Centre at Cardiff College, says: ‘I exploit a nasal decongestant spray containing xylometazoline or oxymetazoline, as they work inside minutes and the results final for as much as ten hours.’
Professor Penny Ward, a visiting professor in pharmaceutical drugs at King’s Faculty London, says: ‘I often wrestle by means of with out taking something, as remedy solely treats the signs, not the virus itself. However I’d typically take a Lemsip at night time to alleviate the signs and for consolation so I can sleep.’
Professor Andrew Easton, a virologist on the College of Warwick, says: ‘I take over-the-counter merchandise similar to Beechams powders or comparable if my signs are fairly unhealthy.’
After trawling by means of information from 29 trials, it concluded: ‘This lack of proof of effectiveness brings into query how these merchandise can proceed to be promoted utilizing language that means that their effectiveness shouldn’t be doubtful.’ However as this analysis was merely including to the proof for and towards cough drugs’s use, somewhat than a regulatory investigation, no motion was taken.
A separate assessment in 2017 by the American Chemical Society reached an identical conclusion — discovering that almost all cough syrups had been no higher than a placebo.
If some treatments are ineffective, shopper selection has been additional restricted by security issues regarding merchandise containing pholcodine.
This March, the MHRA ordered that round 20 over-the-counter cough medicines — together with Day and Night time Nurse and Boots Day Chilly And Flu Reduction — must be withdrawn from the market following an investigation that exposed pholcodine (an opioid-based ingredient that suppresses coughs by interrupting the nerve alerts that set off coughing) elevated the danger of getting a life-threatening allergic response to a basic anaesthetic.
Anybody who had taken cough syrup made with pholcodine within the 12 months earlier than an operation was in danger, the MHRA warned.
And although it pressured that such reactions had been extremely uncommon (affecting solely round one in 10,000 procedures), the merchandise have now been withdrawn from the market within the UK and Europe.
Ointment-based treatments might also not be as efficient as customers consider. Analysis taking a look at merchandise made with plant-based substances similar to menthol, eucalyptus oil and camphor reveals blended outcomes.
So whereas Vicks VapoRub comprises each eucalyptus and camphor (the UK web site says: ‘When you have got a chilly, flip to Vicks VapoRub ointment to alleviate your blocked nostril, sore throat and cough attributable to colds’), the proof means that though such substances might make folks really feel higher, they don’t have any measurable profit on nasal congestion.
A 2022 examine by Cardiff College, revealed within the journal Medication in Context, pooled outcomes from dozens of earlier investigations and located the rub-on treatments ‘didn’t enhance nasal airway measures’, although they did assist folks sleep, which made them really feel a bit higher.
The Proprietary Affiliation of Nice Britain, which represents firms making over-the-counter medicines, insists sufferers shouldn’t be involved by the current report on decongestants.
Michelle Riddalls, its chief govt, mentioned in an announcement: ‘This isn’t a security situation, and the merchandise available on the market within the UK containing phenylephrine are mixed with different lively substances to present the very best symptom reduction.’ Most Excessive Road merchandise do certainly combine decongestants with a spread of different substances, similar to paracetamol or ibuprofen, to carry down temperature and banish aches and pains; or caffeine to fight drowsiness.
The attraction is that they supply all-in-one symptom reduction in a single product. However leaving apart whether or not they really work when it comes to clearing the airways, is a mixture tablet the most secure technique to take them?
‘Very often with nasal congestion, folks additionally get painful blocked sinuses and complications,’ says Professor Peter Openshaw, an knowledgeable in respiratory viral infections primarily based at Imperial Faculty London.
‘Paracetamol is an acceptable therapy for that, as is ibuprofen, which may additionally carry your fever down. However I’d at all times advocate taking these individually — somewhat than in a mixture therapy — to make sure you might be sticking to dosing pointers.’
Beneath NHS pointers an grownup ought to take not more than eight 500mg paracetamol tablets in 24 hours (a complete of 4,000mg).
A 20ml serving of Lemsip Max All in One Liquid, by comparability, comprises 1,000mg of paracetamol.
A 2022 examine by Cardiff College, revealed within the journal Medication in Context, pooled outcomes from dozens of earlier investigations and located the rub-on treatments ‘didn’t enhance nasal airway measures’, although they did assist folks sleep, which made them really feel a bit higher (file picture)
As it may be taken as much as 4 occasions a day, this provides a complete paracetamol consumption of 4,000mg — i.e. the utmost secure each day allowance. The concern is that some sufferers may not realise how a lot of the painkiller is in these merchandise and will take further paracetamol tablets in between doses, says Professor Openshaw.
‘With these mixed therapies, it is easy to lose monitor of precisely how a lot you take, and meaning there may be the potential to overdose on paracetamol, for instance, which may result in liver harm. It is a lot safer if you realize precisely how a lot you take.’
Research present there are as much as 90,000 instances of paracetamol overdose within the UK every year — with 150 to 250 deaths.
The British Liver Belief web site says: ‘Numerous chilly and flu treatments you should purchase from a pharmacy comprise paracetamol. So it’s attainable to by accident take an excessive amount of by taking completely different medicines collectively.’
With regards to nasal congestion, Professor Openshaw recommends over-the-counter sprays. These won’t essentially comprise phenylephrine: some are made with different lively medicine, similar to xylometazoline (used, for instance, in Sudafed blocked nostril spray) or oxymetazoline (present in Vicks Sinex Soother Nasal Spray).
Nonetheless, utilizing them for too lengthy could make congestion worse by triggering rhinitis medicamentosa — a blocked nostril (usually referred to as a rebound impact) attributable to the medication itself.
‘Though the sprays do shrink blood vessels within the lining of the nostril and aid you breathe extra simply, the liner rapidly turns into extra reactive and virtually hooked on the remedy — it’s important to use extra of it to suppress the irritation,’ explains Professor Openshaw. ‘Personally, I’d not use a decongestant spray for greater than three days in a row to cut back the danger of this occurring.
‘One helpful suggestion I’ve seen elsewhere is to restrict publicity to the spray by squirting it up one nostril at a time, because it’s attainable to breathe comfortably by means of one. So possibly squirt it into the left nostril someday and the correct one the subsequent to cut back probabilities of this rebound impact.’
In the meantime, scientists proceed to analyze different approaches for tackling colds and flu.
Remarkably, given its prevalence, the widespread chilly is without doubt one of the few illnesses the place there aren’t any licensed medicines to deal with the virus itself — solely the signs.
A part of the rationale for that’s that there are greater than 200 viruses that may trigger a chilly.
Numerous promising candidates have fallen by the wayside.
SynGEM, a chilly vaccine within the type of a nasal spray developed by scientists at Imperial Faculty London in 2016, generated enormous pleasure when it first emerged however has since been deserted because it failed to draw the funding wanted to take it to main scientific trials.
At the moment probably the most promising therapies is a drug referred to as nitazoxanide, which has been discovered to destroy quite a few viruses — together with people who trigger colds — when taken as a pill. It really works by blocking a protein referred to as hemagglutinin, which rhinovirus (one of many principal cold-causing viruses) wants to duplicate.
It is at present in section 3 trials (the place the drug is examined on bigger teams of individuals) within the U.S., the place volunteers contaminated with a chilly virus are being given a 300mg dose twice a day for 5 days to see if it shortens the length of an infection. The outcomes are anticipated later this yr.
However do not count on a radical breakthrough any day quickly, warns Professor Eccles. ‘The viruses that trigger colds are at all times quickly evolving and stay one step forward of the anti-viral medicines we make — so a treatment appears a good distance off,’ he says. ‘In comparison with the widespread chilly, smallpox was comparatively straightforward to defeat.’
Gadgets and medicines that really work
For years, our go-to decongestant has been capsules containing the lively ingredient phenylephrine — however a panel of specialists has suggested the U.S. Meals and Drug Administration medicines regulator that it isn’t efficient on this kind (see principal piece). We requested specialists to evaluate the helpful options.

‘As with all tablets, a number of the dose will likely be misplaced because it passes by means of the intestine, however the formulation of pseudoephedrine is such that sufficient will attain the nasal passages to be efficient on congestion.

‘We advocate utilizing nasal rinsing for rhinitis and continual sinusitis, and a variety of our sufferers discover these irrigation kits helpful.

‘There are usually not many research, however people who exist recommend a tool like this will enhance respiratory if we now have a blocked nostril — though they will not scale back the viral load.
‘In clinic, we regularly prescribe steroid nasal sprays [to reduce inflammation] with a tool like this for extreme rhinitis. I’ve an identical machine which I exploit if I really feel a little bit of a chilly beginning.’
However notice, whereas it’d loosen mucus, the inhaler will not pace up restoration: a 2017 Cochrane Overview concluded that ‘there may be laboratory proof that the chilly virus could also be delicate to warmth however no large-scale scientific trials have examined its [i.e. steam] effectiveness’.
