BBC News reports that in the matter of Nurofen Plus recall of stock, sabotage is suspected in some packets. "Four packs were found to contain Seroquel XL 50mg. The packs were bought in Victoria, Bromley and Beckenham in south London. Another tampered pack, containing a prescription medicine for epilepsy, was uncovered in Northern Ireland." Seroquel is an antipsychotic drug. "Most people who take one Seroquel will just experience sleepiness, but those on sedatives could feel stronger effects."
So there are dangers, hopefully small, if anyone mistakenly takes Seroquel or possibly an anti-epilepsy drug, and this prudent, well-publicised product recall will minimise those dangers. - But I would like to point out that Nurofen Plus is itself a dangerous drug, despite being an OTC (over-the-counter) medication. - It is a highly addictive painkiller, which should not be taken for more than 3 days because of this highly addictive quality. In overdose, it can also cause serious liver damage and death. It is a mistake to assume that painkillers are harmless drugs. They are not.
