Diclofenac is a potent nonsteroidal anti-inflammatory drug (NSAID) used to treat pain, inflammation, and stiffness associated with various musculoskeletal conditions. It is available in multiple forms, including tablets, gels, patches, and injections, offering flexibility for different treatment needs.
What Is Diclofenac Used For?
- Osteoarthritis and rheumatoid arthritis pain
- Acute musculoskeletal injuries such as sprains and strains
- Post-operative pain management
- Menstrual pain
- Migraine relief in some formulations
- Localized joint or muscle pain, often treated with topical gel forms
How Does Diclofenac Work?
Diclofenac inhibits cyclooxygenase (COX) enzymes, reducing the production of prostaglandins responsible for pain, inflammation, and fever. Topical formulations work locally at the site of application, providing relief with reduced systemic absorption compared to oral forms.
General Dosage Information
- Oral adult doses typically range from 50mg to 150mg daily, divided into two or three doses, as prescribed by a doctor.
- Topical gel is usually applied to the affected area two to four times daily, following product instructions.
- It is generally recommended to take oral diclofenac with food to reduce stomach irritation.
- Treatment duration should be as short as possible to control symptoms, especially for oral forms.
Side Effects of Diclofenac
- Stomach upset, heartburn, or indigestion
- Increased risk of stomach ulcers or gastrointestinal bleeding with oral use
- Headache or dizziness
- Fluid retention
- Increased cardiovascular risk with long-term or high-dose use
- Skin irritation with topical application
Who Should Be Cautious?
- People with a history of stomach ulcers or gastrointestinal bleeding
- Those with heart disease, high blood pressure, or history of stroke
- People with kidney impairment
- Pregnant women, particularly in the third trimester
Drug Interactions
- Blood thinners such as warfarin, increasing bleeding risk
- Other NSAIDs or aspirin, raising gastrointestinal and cardiovascular risks
- Blood pressure medications, potentially reducing their effectiveness
- Certain diuretics, with possible reduced effect and kidney strain when combined
Storage and Precautions
Store tablets and gels at room temperature away from moisture and heat. Avoid applying topical diclofenac to broken or irritated skin, and wash hands after application unless treating the hands themselves.
Frequently Asked Questions
Is topical diclofenac safer than oral tablets? Topical forms generally have fewer systemic side effects since less medicine enters the bloodstream, making them a reasonable option for localized pain in appropriate cases.
Can diclofenac be used for long-term arthritis management? It can be, but long-term use requires medical supervision due to gastrointestinal and cardiovascular risks.
Can I use diclofenac gel and oral tablets together? This should only be done under medical guidance, as combining forms can increase the total dose and side effect risk.
