NSAID Painkiller with Local Anaesthetic
Last reviewed July 2026
Who is this for?
This is an injectable combination of diclofenac (a strong painkiller and anti-inflammatory drug) and lidocaine (a numbing agent that reduces the pain of the injection itself). Diclofenac works by blocking chemicals in your body that cause pain, swelling, and inflammation, while lidocaine numbs the injection site so it hurts less going in.
Inhibits COX-1 and COX-2 enzymes, reducing prostaglandin synthesis to decrease pain and inflammation, whilst lidocaine blocks sodium channels in nerve membranes to provide local anaesthetic effect and enhance pain relief.

Since this injection is given by a healthcare professional, missed doses are unlikely. If you were scheduled for a dose and missed your appointment, go as soon as you can or contact your doctor for advice on when to take the next dose.
Always get this injection from a qualified nurse or doctor at a hospital or registered clinic, never from unqualified persons or roadside medicine vendors. Do not use this injection for more than 2 days; prolonged use increases the risk of serious side effects. The brand Olfen 75 Injection is available in Nigeria, so make sure you buy from a reputable pharmacy to avoid counterfeit products.
Avoid taking with other painkillers like ibuprofen or aspirin as this increases the risk of stomach bleeding. If you are on blood pressure medication (like lisinopril or amlodipine), diclofenac can reduce their effectiveness. Avoid alcohol as it increases the risk of stomach bleeding and liver damage.
