A dolor de garganta usually goes after a few days. Simple treatments that you can buy can ease symptoms until the sore throat goes. Usually, you would only need to see a doctor if your symptoms are severe, unusual, or do not ease within 3-4 days.

Flurbiprofen belongs to the group of medicines known as medicamentos antiinflamatorios no esteroides (AINEs). These medicines are used to relieve pain and swelling (inflammation). Flurbiprofen lozenges are used to ease the symptoms of a sore throat. You can buy them without a prescription at pharmacies.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using flurbiprofen lozenges it is important that your doctor or pharmacist knows:

  • Si tienes asma u otro trastorno alérgico.

  • Si alguna vez has tenido una úlcera gástrica o duodenal, o si tienes un trastorno inflamatorio intestinal como la enfermedad de Crohn o la colitis ulcerosa.

  • Si estás embarazada o amamantando.

  • If you are under 12 or over 65 years of age.

  • Si tienes problemas de hígado o riñón.

  • Si tienes una afección cardíaca, o un problema con tus vasos sanguíneos o circulación.

  • Si tienes presión arterial alta.

  • Si alguna vez has tenido problemas de coagulación sanguínea.

  • Si tienes una condición inflamatoria llamada lupus eritematoso sistémico (también conocido como lupus o LES).

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

  • Si alguna vez ha tenido una reacción alérgica a cualquier otro AINE (como aspirina, ibuprofeno, diclofenaco e indometacina), o a cualquier otro medicamento.

  • Before using these lozenges, read the manufacturer's printed information leaflet from inside the pack and take them exactly as directed.

  • You can suck one flurbiprofen lozenge every three to six hours if needed. Move the lozenge around in your mouth as you allow it to slowly dissolve. Do not use more than five lozenges in any 24-hour period.

  • You should not use flurbiprofen lozenges for more than three days unless you have been directed to do so by your doctor.

  • Have plenty to drink, even though it is tempting not to drink very much when it is painful to swallow. You may become mildly lacking in fluid in the body (dehydrated) if you don't drink much, particularly if you also have a high temperature (fever).

  • If your sore throat does not begin to feel better within three days, ask for further advice from your pharmacist or doctor.

  • If you buy any medicines, check with a pharmacist that they are safe to take alongside these lozenges. You should not take or use any other anti-inflammatory painkillers (such as aspirin, ibuprofen, diclofenac, and naproxen).
