Severe cutaneous adverse reactions (SCARs)
Severe cutaneous adverse reactions (SCARs), including exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome (SJS), Toxic Epidermal Necrolysis (TEN), Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS syndrome), and acute generalized exanthematous pustulosis (AGEP), which can be life-threatening or fatal, have been reported in association with the use of ibuprofen (see section 4.8). Most of these reactions occurred within the first month.
If signs and symptoms suggestive of these reactions appear ibuprofen should be withdrawn immediately and an alternative treatment considered (as appropriate).
Not recommended for children under 12 years.
Oral NSAIDs, including ibuprofen, can sometimes be associated with renal impairment, aggravation of active peptic ulcers, and can induce allergic bronchial reactions in susceptible asthmatic patients. Although the systemic absorption of topically applied ibuprofen is less than for oral dosage forms, these complications can occur in rare cases. For these reasons, patients with an active peptic ulcer, a history of kidney problems or asthma should seek medical advice before using Ibuprofen gel as should patients already taking other painkillers.
Patients should seek medical advice if symptoms worsen or persist.
Patients should be advised against excessive exposure to sunlight of area treated in order to avoid possibility of photosensitivity.
Instruct patients not to smoke or go near naked flames - risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.
This medicine contains 1.25 mg benzyl alcohol in each 125mg, which is equivalent to 0.01mg/mg. Benzyl alcohol may cause allergic reactions and mild local irritation.
This medicine contains less than 1 mmol sodium (23 mg) per 125mg, that is to say essentially 'sodium-free'.
4.5. Interaction with other medicinal products and other forms of interaction
Non-steroidal anti-inflammatory drugs may interact with blood pressure lowering drugs, and may possibly enhance the effects of anticoagulants, although the chance of either of these occurring with a topically administered preparation is extremely remote. Concurrent aspirin or other NSAIDS may result in an increased incidence of adverse reactions.
4.6. Fertility, pregnancy and lactation
Not to be used during pregnancy or breast-feeding.
Pregnancy:
Although no teratogenic effects have been demonstrated, ibuprofen should be avoided during pregnancy. The onset of labour may be delayed and the duration of labour increased.
There are no clinical data from the use of topical forms of Fenbid Forte Gel during pregnancy. Even if systemic exposure is lower compared with oral administration, it is not known if the systemic Fenbid Forte Gel exposure reached after topical administration can be harmful to an embryo/fetus. During the first and second trimester of pregnancy, Fenbid Forte Gel should not be used unless clearly necessary. If used, the dose should be kept as low and duration of treatment as short as possible.
During the third trimester of pregnancy, systemic use of prostaglandin synthetase inhibitors including Fenbid Forte Gel may induce cardiopulmonary and renal toxicity in the fetus. At the end of the pregnancy prolonged bleeding time in both mother and child may occur, and labour can be delayed. Therefore, Fenbid Forte Gel is contraindicated during the last trimester of pregnancy (see Section 4.3)
Breast-feeding:
Ibuprofen appears in breast milk in very low concentrations but is unlikely to affect breast fed infants adversely.
Fertility:
No data available
4.7. Effects on ability to drive and use machines
Not relevant.

The following adverse reactions are classified by system organ class and ranked under heading of frequency using the following convention:
Uncommon (≥1/1,000 to <1/100)

2Renal impairment can occur in patients with a history of kidney problems.
