Indications & Uses

Pharmacology

Diclofenac Sodium is a potent nonsteroidal anti-inflammatory drug (NSAID) with marked pain-relieving and fever-reducing properties, along with some uricosuric effect. Its action appears to be linked to the inhibition of prostaglandin synthesis: Diclofenac blocks cyclooxygenase, the enzyme responsible for converting arachidonic acid into prostaglandin precursors. After injection, peak plasma concentration is reached within half an hour.

Lidocaine Hydrochloride is the most widely used local anaesthetic. It works faster and is more stable than most other local anaesthetics, making it a very useful surface anaesthetic. Like other local anaesthetics, it impairs the generation and conduction of nerve impulses by slowing depolarization. Its onset of anaesthesia is rapid, with effects lasting 1 to 2 hours.

Dosage Reference

Reference Information Only

Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.

Adults:

Adults: One ampoule given once daily by intramuscular injection; in severe cases, this may be increased to twice daily. For renal colic, one ampoule is given once daily by intramuscular injection, with a second dose after 30 minutes if needed. Children: For juvenile chronic arthritis, 1 to 3 mg of Diclofenac Sodium per kg of body weight daily, given in divided doses. Elderly patients: Elderly or debilitated patients should generally be given the lowest effective dose, based on their age and physical condition, or as advised by the physician.

Side Effects

Side effects with Diclofenac Sodium and Lidocaine injection are usually mild and transient, but the injection should be stopped if a serious reaction develops. Patients may notice gastrointestinal discomfort, nausea, diarrhea and, occasionally, bleeding. Very rarely, disorders at the injection site can occur, and isolated cases of abscess and local tissue necrosis have been reported. Effects attributable to the Lidocaine component mainly involve the CNS; these are usually brief and dose related, and may show up as drowsiness, dizziness, disorientation, confusion, lightheadedness and similar CNS symptoms.

Cautions & Contraindications

Warnings & Precautions

Renal: Patients with severe liver, heart, or kidney impairment, as well as elderly patients, should be closely monitored, since NSAIDs like this one can worsen kidney function. The lowest effective dose should be used, and kidney function should be checked periodically. Hepatic: If liver function tests remain abnormal or worsen, if signs or symptoms of liver disease appear, or if other reactions such as eosinophilia or rash occur, Diclofenac should be stopped. All patients on long-term NSAID therapy should be monitored regularly as a precaution, including checks of kidney function, liver function, and blood counts.

Contraindications

Contraindicated in patients hypersensitive to Diclofenac. It should also not be used in those with active or suspected peptic ulcer, gastrointestinal bleeding, or a history of asthma attacks, urticaria, or acute rhinitis triggered by Aspirin or other NSAIDs with prostaglandin synthetase-inhibiting activity. Because it contains Lidocaine, this injection is likewise contraindicated in patients hypersensitive to amide-type local anaesthetics, though such reactions are very rare. It should not be given to patients with Adams-Stokes syndrome or severe SA, AV, or intraventricular heart block who do not have an artificial pacemaker in place, or to those hypersensitive to any excipient in the formulation (Sodium Metabisulphite, Disodium Edetate, Benzyl Alcohol, Sodium Hydroxide, Propylene Glycol).

Pregnancy & Breastfeeding

Pregnancy: This medicine should not be used during pregnancy unless the potential benefit clearly justifies the risk, and if it must be used, the lowest effective dose is advised. It is not recommended in the final trimester of pregnancy.

Breastfeeding: Only trace amounts of Diclofenac pass into breast milk, and at these levels the infant is not expected to experience any harmful effects.

⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
