Diclofenac
Diclofenac is a common, low strength pain killer. Brand names include; Dicloflex, Diclomax, Econac, Motifene and Voltarol.
This drug should be avoided, where possible, by those with asthma as there is a risk of an asthmas attack, urticaria (hives), angioedema (swelling) or rhinitis (inflammation inside the nose).1
You must not combine diclofenac with other NSAIDs such as aspirin, ibuprofen or naproxin.
You can combine this with co-codamol and could combine it with codeine, fentanyl or morphine but the either of these would likely be a replacement.
