Both can help. These medications are in 2 different classes. Naproxen is an NSAID and hydrocodone is an opioid and probably also has tylenol. If you don't have major kidney disease or stomach ulcers, Naproxen should be the safer of the 2. If inadequate, hydrocodone can be added until no longer needed. Use all meds as directed and carefully note all sources of acetaminophen/tylenol-3000mg/day max!
Naproxen. The best medication for pain relief after a car accident is naproxen. Hydrocodone is a narcotic. It may give temporary relief but it is not a long term answer for this type of pain. It can cause dependence and long-term studies do not show any long-term benefit to the use of hydrocodone. When weighing the risks, Naproxen is a better choice.
