Lidet contains naproxen as the active substance, which belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines are used to reduce inflammation and pain in the joints and muscles.

This medicine is indicated for the treatment of symptoms of rheumatoid arthritis, osteoarthritis, ankylosing spondylitis (inflammation that affects the joints of the spine), acute musculoskeletal disorders (such as sprains and strains) and dysmenorrhea (menstrual pain), in patients over 16 years of age.

2. What you need to know before you take Lidet

• If you are allergic to acetylsalicylic acid (aspirin), other NSAIDs (such as ibuprofen or diclofenac) or any other pain relief medicine, or if you have asthma, rhinitis, nasal polyps or urticaria.
• If you have or have had nasal polyps, sneeze or have a runny nose frequently, have a stuffy nose or feel itchy (rhinitis).
• If you have asthma or allergies (such as hay fever) or have ever had swelling of the face, lips, eyes or tongue.

Warnings and precautions

If you have heart problems, have had a stroke or think you may be at risk of these diseases (for example, if you have high blood pressure, diabetes or high cholesterol or smoke), you should consult your doctor or pharmacist before taking this medicine.

Consult your doctor or pharmacist before starting to take this medicine if any of the following apply to you:

• If you have asthma or allergic disorders (such as rhinitis or nasal polyps), or have had swelling of the face, lips, eyes or tongue in the past.
• If you have a feeling of weakness (perhaps due to an illness) or you are an elderly person.
• If you have nasal polyps or if you sneeze frequently or have a runny nose, or itchy or congested nose (rhinitis).

• If you have an autoimmune condition, such as systemic lupus erythematosus (SLE, which causes joint pain, skin rashes and fever) and ulcerative colitis or Crohn's disease (conditions that cause intestinal inflammation, abdominal pain, diarrhea, vomiting and weight loss).

Medicines like Lidet may be associated with a small increased risk of heart attack (myocardial infarction) or stroke. At higher doses and longer treatments, there is a greater risk of this happening. Do not exceed the recommended dose or treatment duration.

There have been reports of severe skin reactions, including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (Lyell's syndrome), and drug reaction with eosinophilia and systemic symptoms (DRESS), in association with naproxen. Stop taking naproxen and consult your doctor immediately if you notice any of the symptoms related to severe skin reactions described in section 4.

There have been reports of photosensitivity reactions (including cases where the skin resembles late cutaneous porphyria, "pseudoporphyria"). If skin fragility, blisters or other symptoms suggestive of pseudoporphyria occur, treatment should be discontinued and the patient monitored.

If you are in any of the above situations, or if you are not sure, consult your doctor or pharmacist before taking this medicine.

Pregnancy, breastfeeding and fertility

• Do not take naproxen if you are in the last 3 months of pregnancy, as it may harm the fetus or cause problems during delivery. It may cause kidney and heart problems in your fetus. It may affect your tendency and that of your baby to bleed and delay or prolong delivery more than expected.

• From the 20th week of pregnancy, Lidet may cause kidney problems in your fetus if taken for more than a few days, which can cause low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for more than a few days, your doctor may recommend additional checks.
• Do not take naproxen if you are breastfeeding (or plan to).
• If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
• Lidet may make it harder to become pregnant. You should tell your doctor if you are planning to become pregnant or if you are having trouble becoming pregnant.
