Pregnancy, breast-feeding and fertility

Do not take this medicine if you are in the last 3 months of pregnancy. You should not use (this medicine) during the first 6 months of pregnancy unless clearly necessary and advised by your doctor. If treatment is needed during this period, the lowest effective dose for the shortest time possible should be used.

Flurbiprofen belongs to a group of medicines which may impair fertility in women. This effect is reversible on stopping the medicine. It is unlikely that the lozenges, used occasionally, will affect your chances of becoming pregnant; however, tell your doctor before taking this medicine if you have problems becoming pregnant.

Infections

Non-steroidal anti-inflammatory drugs (NSAIDs) may hide signs of infections such as fever and pain. This may delay appropriate treatment of infection, which may lead to an increased risk of complications. If you take this medicine while you have an infection and your symptoms of the infection persist or worsen, consult a doctor or pharmacist without delay.

Driving and using machines

No studies on the effects on the ability to drive and use of machines have been performed. However, dizziness and visual disturbances are possible side effects after taking NSAIDs. If affected, do not drive or operate machinery.

3. HOW TO TAKE THIS MEDICINE

Always use this medicine exactly as described in this leaflet or as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Adults, the elderly and children aged 12 years and older:

Do not give to children under 12 years.

These lozenges are for short-term use only. The lowest effective dose should be used for the shortest duration necessary to relieve symptoms. If you have an infection, consult a doctor or pharmacist without delay if symptoms (such as fever and pain) persist or worsen (see section 2). If mouth irritation occurs, flurbiprofen treatment should be withdrawn.

Do not take for longer than 3 days unless your doctor tells you to. If symptoms persist or the pain worsens, or if any new symptoms occur, consult your doctor or pharmacist.
