4 CLINICAL PARTICULARS
4.1 Therapeutic indications

Children: Contraindicated below the age of 16 years.
4.3 Contraindications
Hypersensitivity to any of the constituents.
Not to be used in children and adolescents under the age of 16. This is because there is a possible association between salicylates and Reye’s Syndrome when given to children. Reye’s Syndrome is a very rare disease which affects the brain and liver and can be fatal.

4.5 Interaction with other medicinal products and other forms of interaction
None known.
4.6 Pregnancy and lactation
Animal studies are insufficient with respect to effects on pregnancy and-or embryonal/foetal development. The potential risk for humans is unknown. Caution should be exercised when prescribing to pregnant women.
Anthranoid glycosides derived from rhubarb may be excreted in breast milk. However, at therapeutic doses of PYRALVEX, it is not known whether these, or salicylic acid are excreted in breast milk. A decision on whether to continue breastfeeding or to continue therapy with PYRALVEX should be made taking into account the benefit of breast-feeding to the child and benefit of PYRALVEX therapy to the woman.

Overdose associated with local application is unlikely, although the extent of systemic absorption of salicylic acid and anthranoid derivatives is not known. Systemic overdose following ingestion might lead to abdominal cramping, diarrhoea and possibly salicylism (presenting as hyperventilation, tinnitus, deafness, vasodilation, sweating).
Salicylate toxicity can result if stated frequency of application is exceeded. Do not exceed the stated frequency of application.
