Lemsip flu 12hr

How does it work?

Lemsip flu 12hr capsules contain two active ingredients, ibuprofen (300mg) and pseudoephedrine hydrochloride (45mg).

Ibuprofen is a type of medicine called a non-steroidal anti-inflammatory drug (NSAID). It is a simple painkilling medicine used to relieve mild to moderate pain, inflammation and fever.

Ibuprofen works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced in response to injury and certain diseases and conditions, and cause pain, swelling and inflammation. NSAIDs block the production of these prostaglandins and are therefore effective at reducing inflammation and pain.

Ibuprofen also reduces fever by reducing the production of prostaglandins. Fever is associated with an increase in prostaglandins in the brain, and these prostaglandins cause the body temperature to increase. By reducing prostaglandins in the brain, ibuprofen lowers body temperature and hence reduces fever.

Pseudoephedrine is a type of medicine called a decongestant. It works by acting on alpha receptors that are found in the walls of blood vessels in the linings of the nasal passages and sinuses. It causes these blood vessels to contract and narrow, thereby decreasing blood flow into the linings of the nose and sinuses. This reduces the feeling of congestion and also reduces the production of mucus, helping to relieve a blocked nose.

The combination of active ingredients in Lemsip flu 12hr capsules helps to relieve the symptoms of colds and flu, such as headache, aches and pains, fever, runny nose and nasal or sinus congestion and pain. The capsules are modified release capsules designed to be taken twice a day. For adults and children over 12 years of age, two capsules should be taken, followed by another two capsules after 12 hours if necessary. No more than four capsules should be taken in 24 hours.

What is it used for?

Relieving symptoms of colds and flu, such as headache, sore throat, aches and pains, fever and nasal or sinus congestion.

Warning!

Lemsip flu 12hr capsules should be swallowed whole and not broken, crushed or chewed, as this would damage the modified release action of the medicine.

Do not exceed the recommended dose of this medicine. This medicine is for short-term use only. If symptoms persist despite treatment, seek medical advice from your doctor or pharmacist.

Ibuprofen is generally well-tolerated and most people do not experience any side effects. The most common side effects are related to stomach irritation and include abdominal pain, indigestion and nausea. These can mainly be avoided by taking the ibuprofen with food. Rarely, serious side effects such as ulceration or bleeding of the stomach or intestines may occur. These are more likely with high doses and in elderly people. If any signs of bleeding from the stomach or bowels are experienced, such as vomiting blood and/or passing black/tarry/bloodstained stools, you should consult your doctor immediately.

This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy. If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.

Pregnancy and Breastfeeding

Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.

This medicine is not recommended for use during pregnancy, unless considered essential by your doctor. In particular, it should not be taken in the third trimester, as ibuprofen may delay labour, increase the length of labour and cause complications in the newborn baby. The safety of pseudoephedrine during pregnancy has not been established. Some evidence suggests that NSAIDs should also be avoided by women attempting to conceive, as they may temporarily reduce female fertility during treatment and may also increase the risk of miscarriage or malformations. Seek medical advice from your doctor.

Small amounts of ibuprofen and pseudoephedrine may pass into breast milk, but this is not expected to be harmful to a nursing infant. However, as with all medicines, you should seek medical advice from your doctor or pharmacist before taking this medicine if you are breastfeeding.
