Is the Diclofenac a good pain killer?

Diclofenac is an excellent pain killer for general and musculoskeletal pain and reduces the signs of inflammation. However, for more severe types of pain, you may need to resort to more potent painkillers.

Which is more potent? Ibuprofen or Diclofenac?

Diclofenac is more potent than ibuprofen. That's why ibuprofen is safe for children and minor pain. However, if ibuprofen is not working, you may need to go for Diclofenac.

What if I feel no relief with Diclofenac?

If you have no relief, you may resort to more potent NSAIDs, steroids or even analgesics for pain treatment at the instruction of your doctor.

Is ibuprofen the same as Diclofenac?

No. Both are different drugs but belong to the same group. Ibuprofen is available over the counter, while Diclofenac is strictly available on prescription. Ibuprofen has more margin of safety and is safe for children too.

Is ibuprofen safe during pregnancy?

Diclofenac is a very potent NSAID and is not suitable for pregnant women, particularly in the first 20 weeks, unless prescribed by the doctor. Besides disturbing the pregnancy, it can cause kidney and Heart issues in the baby.

Can I use alcohol and coffee with Diclofenac?

Diclofenac can cause stomach upsets. To avoid these side effects, it is better to use them with food and avoid alcohol, coffee and spicy foods.
