Flu cases have surged across Ireland this winter, with hospitals experiencing a rise in admissions due to the seasonal illness. However, for many, battling a cold or flu is typically done at home, and there are some crucial pieces of information you should know before treating it with medication.
A pharmacist has issued an important warning about the use of paracetamol, as there are some easy-to-overlook facts about the common medication that many may not be aware of. While it’s popularly used to alleviate fevers and reduce pain, there are certain circumstances where you should avoid taking it.
A medical expert, known as Pharmacist Anum, has shared the key health information on social media. This comes after people were told to stay at home if they’re displaying certain flu-like symptoms.
In a video, the pharmacist said: “If you’re buying over-the-counter cold and flu remedies at your pharmacy, you need to watch this video. These are the things that you don’t want to mix with popular cold and flu remedies.
“So think things like Lemsip, Day Nurse, Benylin, anything like this, you do not want to be taking alongside paracetamol or any other paracetamol-containing medication. The reason being is that they already contain paracetamol. So, if you’re taking paracetamol in addition, you’re running the risk of overdosing. You also want to be careful with nighttime-specific remedies.”
She continued: “Things like Night Nurse, Benylin Night, cough syrup, to name a few. These often contain sedating antihistamines, so please do not take any antihistamines on top of this.
“What are antihistamines? Things like cetirizine, loratadine, fexofenadine. All that will happen is that it will make you so much more drowsy and increase the risk of side effects. If you’re ever unsure, speak with your pharmacist.” In essence, that’s everything you need to know to navigate the winter months safely.

Whilst paracetamol can help ease flu symptoms, it’s crucial to avoid taking too much, as numerous cold and flu treatments already include paracetamol. The important thing is to always examine the label of any multi-symptom medication.
Never combine paracetamol with other products containing paracetamol to prevent overdose, and always consult a pharmacist if you’re uncertain. The HSE also has guidance surrounding the use of paracetamol and combating flu.
A section of the HSE website reads: “A pharmacist can give you treatment advice and recommend flu remedies. Avoid flu remedies that contain paracetamol if you’re already taking paracetamol. Check this with your pharmacist. Phone a pharmacy or contact them online before going in person. You can get medicines delivered or ask someone to collect them.
It also highlighted that flu typically resolves itself over time; however, it can cause severe illness in some individuals. This underscores the importance of receiving the flu vaccine if recommended.
