Diclofenac potassium is an NSAID (non-steroidal anti-inflammatory drug) used to relieve pain and reduce inflammation. It’s the potassium salt form of diclofenac and is absorbed more quickly than the diclofenac sodium form, which can lead to a faster onset of relief in some people.
Key points
- Common uses: short-term relief of mild to moderate pain due to headaches, dental pain, menstrual cramps, muscle or joint injuries, and inflammatory conditions.
- How to take: follow the product label. Typical adult dosing is around 50 mg every 6–8 hours as needed, with a maximum of about 150 mg per day. Some forms (like effervescent tablets) may have different instructions. Take with food or milk to help with stomach upset.
- Side effects: common are GI upset (stomach pain, nausea, heartburn), dizziness, or headaches. Serious but less common: GI bleeding/ulcers, kidney or liver problems, high blood pressure or heart-related issues, allergic reactions. Seek medical attention if you notice black/tarry stools, vomiting blood, chest pain, severe rash, or swelling.
- Precautions: use the lowest effective dose for the shortest time. Not suitable for people with active GI ulcers or bleeding, severe kidney or liver disease, uncontrolled heart failure, or known NSAID allergies. Use in pregnancy is generally avoided, especially in the later trimesters; discuss with a clinician if you are breastfeeding. Elderly or those with kidney disease, high blood pressure, or taking other NSAIDs or anticoagulants should use with caution and under medical advice.
- Interactions: may interact with anticoagulants/antiplatelets (e.g., warfarin, aspirin), other NSAIDs, certain antidepressants, blood pressure meds (ACE inhibitors/ARBs), diuretics, and methotrexate or lithium. Your clinician or pharmacist can check for interactions with your meds.
- Availability: in some countries diclofenac potassium tablets are prescription-only; in others there are OTC forms or different formulations. Check local labeling and talk to a pharmacist if you’re unsure.
