The mechanism of action
Naprosyn belongs to a class of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Other members of this class include ibuprofen (Motrin), indomethacin (Indocin), nabumetone (Relafen) and several others. These drugs are used to treat mild and moderate pain, fever and inflammation. They work by reducing levels of prostaglandins and chemicals, which are responsible for pain, fever and inflammation. Naproxen blocks the enzyme that is responsible for the formation of prostaglandins (COX), which leads to lower concentrations of prostaglandins. As a consequence, inflammation, pain and fever are reduced. Naproxen has been approved by the FDA in December 1991.
If you are taking Naprosyn on a regular basis, take the missed dose as soon as you remember. However, if it occurred during the next dose, skip the missed one and take only the next dose. Do not take a double dose. If you are taking Naprosyn as needed, take the missed dose if necessary, and then wait for recommended or prescribed amount of time before taking another dose.
Naprosyn suspension is kept at room temperature, without overheating, above 40 degrees C (104 ° F). Keep it in the light-resistant containers. Naprosyn tablets are kept at room temperature in a tightly closed container, in such case it is possible to manage without the light-resistant containers.
