Cataflam (Generic Diclofenac) Overview
Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) commonly sold under the brand name Cataflam. It belongs to the class of medications designed to reduce pain, inflammation, and fever by blocking enzymes that produce inflammatory substances in the body. The generic version of diclofenac works exactly like the brand-name drug but is significantly more affordable, making it an excellent cost-effective alternative to brand-name drugs for many patients.
Diclofenac is prescribed for various conditions including arthritis, menstrual cramps, dental pain, headaches, and post-surgical pain. It's available in multiple forms: tablets, immediate-release formulations, and extended-release versions. The medication works by inhibiting cyclooxygenase (COX) enzymes, which are responsible for producing prostaglandins—hormone-like substances that cause inflammation and pain. Understanding generic vs brand-name drugs can help you make informed choices about your pain management options.
Generic diclofenac is regulated by the FDA to ensure it has the same active ingredient, strength, dosage form, and route of administration as the brand-name version. This means you're getting the same therapeutic benefit at a fraction of the cost. Many people choose generic versions specifically because of this equivalence combined with significant savings on medication expenses.
Side Effects
Diclofenac is generally well tolerated by most people, but like all medications, it can cause side effects. Understanding what to expect helps you use this medication safely and know when to contact your healthcare provider.
Common Side Effects
Stomach upset and indigestion – Nausea, abdominal discomfort, or heartburn may occur, especially if taken without food. Taking diclofenac with food or milk can help minimize these symptoms.
Dizziness or lightheadedness – Some people experience mild dizziness, particularly when standing up quickly. This usually subsides as your body adjusts to the medication.
Headache – Tension headaches can develop in some patients, though this typically resolves with continued use.
Rash or itching – Mild skin reactions may appear on the skin surface and often disappear without treatment.
Fluid retention – Mild swelling in the legs, ankles, or feet can occur as diclofenac may affect how your body handles sodium and water.
Serious Side Effects
Gastrointestinal bleeding – This is one of the most serious risks of NSAIDs. Signs include vomiting blood, black or tarry stools, and severe abdominal pain. Seek immediate medical attention if you experience these symptoms.
Kidney problems – Diclofenac can affect kidney function, particularly in people with pre-existing kidney disease, dehydration, or those taking certain other medications. Symptoms may include decreased urination or swelling.
Cardiovascular events – NSAIDs like diclofenac may increase the risk of heart attack or stroke, especially with long-term use or in people with existing heart disease.
Severe allergic reactions – Though rare, anaphylaxis can occur, presenting as difficulty breathing, facial swelling, or severe rash. This requires emergency medical care.
Liver problems – Elevated liver enzymes or hepatotoxicity can develop with prolonged use, potentially causing jaundice or dark urine.
When to Seek Medical Attention
Contact your healthcare provider immediately if you experience severe abdominal pain, vomiting blood, black stools, chest pain, shortness of breath, or signs of an allergic reaction. Don't wait to see if symptoms resolve on their own—these could indicate serious complications requiring prompt medical evaluation.
If you notice persistent nausea, unusual bruising, decreased urination, or swelling that worsens despite taking the medication as directed, call your doctor as soon as possible. Your clinician can assess whether diclofenac is still appropriate for you or if an alternative treatment might be safer.

Drug Interactions
Diclofenac can interact with numerous medications and substances, potentially reducing its effectiveness or increasing the risk of side effects. Always inform your healthcare provider about all medications, supplements, and over-the-counter products you're taking before starting diclofenac.
Blood Thinners (Warfarin, Aspirin, Clopidogrel)
Combining diclofenac with blood thinners significantly increases the risk of bleeding, including gastrointestinal bleeding and hemorrhagic stroke. Using these medications together requires careful monitoring and may not be recommended.
ACE Inhibitors and ARBs (Lisinopril, Losartan)
Diclofenac can reduce the effectiveness of these blood pressure medications and increase the risk of kidney damage. Your doctor may need to adjust dosages or choose alternative pain relief options.
Methotrexate
NSAIDs like diclofenac can reduce the clearance of methotrexate, leading to toxic buildup in your body. This combination requires close medical supervision and regular blood tests to monitor toxicity.
Lithium
Diclofenac may increase lithium levels in your blood, potentially causing lithium toxicity with symptoms like tremors, confusion, and kidney problems. Your doctor may need to monitor lithium levels more frequently.
Diuretics (Furosemide, Hydrochlorothiazide)
NSAIDs can reduce the effectiveness of diuretics and increase your risk of kidney problems and electrolyte imbalances. Combined use should be monitored carefully by your healthcare provider.
Other NSAIDs (Ibuprofen, Naproxen)
Taking diclofenac with other NSAIDs dramatically increases the risk of gastrointestinal bleeding and kidney damage. Never combine multiple NSAIDs unless explicitly directed by your doctor.

Frequently Asked Questions
Get answers to common questions about Cataflam (Generic Diclofenac).
Yes, generic diclofenac is therapeutically equivalent to brand-name Cataflam. The FDA requires generic medications to contain the same active ingredient in the same strength and dosage form. Generic vs brand-name drugs provide identical clinical benefits at a lower cost, making generic diclofenac an excellent choice for affordable pain management.
Yes, and you should! Taking diclofenac with food, milk, or antacids can help reduce stomach upset and gastrointestinal irritation. However, food may slightly slow absorption, so if you need faster pain relief, take it on an empty stomach and monitor for stomach discomfort. Your pharmacist can provide specific guidance based on your individual situation and tolerance.
Use diclofenac for the shortest duration possible at the lowest effective dose. For acute pain, most people take it for a few days to two weeks. Long-term use increases risks of gastrointestinal bleeding, cardiovascular events, and kidney problems. If you need pain relief for more than two weeks, discuss ongoing management with your healthcare provider.
If you miss a dose, take it as soon as you remember, unless it's almost time for your next scheduled dose. In that case, skip the missed dose and resume your regular dosing schedule. Never double your dose to make up for a missed one, as this increases the risk of side effects and overdose.
Yes, diclofenac can interact with many OTC products, particularly other pain relievers and anti-inflammatory medications. Never combine diclofenac with ibuprofen, naproxen, or aspirin without medical approval. Always inform your doctor or pharmacist about all OTC medications, supplements, and herbal products you're taking before starting diclofenac.
