Frequently Asked Questions about Diclofenac

1. Is diclofenac safe in pregnancy?

No. Diclofenac is strictly prohibited in the third trimester of pregnancy as it may cause serious heart and kidney damage to the growing fetus. It can also cause miscarriage, premature delivery, and bleeding in the fetus, and reduce the amniotic fluid in the womb causing fetal death. Diclofenac is also not recommended for breastfeeding mothers.

Always consult a physician about the dosage amount and instructions of proper intake.

3. How does diclofenac work?

Diclofenac works by inhibiting the hormones that cause pain and inflammatory reactions, like prostaglandins. It is highly soluble in lipids. Hence, it can pass the blood-brain barrier to decrease the synthesis of molecules that can cause pain. This makes it unique among other NSAIDs. It is effective for 11 hours for joint pain.

4. How long can you take diclofenac?

You should take diclofenac strictly as per the doctor's prescription. Minor sprains like back pain or toothache require 1?2 days to recover. For more chronic pain like arthritis, long-term use is needed. Your doctor would advise the lowest dose for the briefest time, sometimes combined with other medicines for minimal side effects.

Diclofenac is safe for moderate and mild problems. However, long-term usage has many side effects like ulcer formation, stomach disorder, dizziness, nausea, and temporary loss of cognitive abilities. The most serious cases can cause renal failure and heart attacks. So, check with your doctor if you feel sick after taking the medicine.

6. How to take diclofenac?

You should take diclofenac depending on the need and after proper medical consultation. Ingest the diclofenac tablets or capsules whole with water.

8. What does diclofenac do to the body?

Diclofenac blocks inflammatory chemicals like prostaglandins and leukotrienes (pro-inflammatory agents) in the body. It decreases pain by preventing the production of pain-causing agents, thus blocking the accumulation of inflammatory chemicals. It also prevents bacterial infection by disrupting bacterial DNA production. It blocks different ion channels on cell surfaces to prevent the passage of inflammatory chemicals into the bloodstream.

9. Do you need a prescription for diclofenac?

Yes. You need a prescription for diclofenac tablets, capsules, and suppositories as they are potentially dangerous. Diclofenac gels and patches (for external use only) are available without prescription for pain relief of joints like knees, ankles, elbows, wrists, arms, etc. A topical solution of diclofenac, Pennsaid, is prescribed only for severe osteoarthritis pain alleviation.
