How to use EC-Naprosyn
Read the Medication Guide provided by your pharmacist before you start using naproxen and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually twice daily with or without food. Swallow this medication whole. Do not break, crush, or chew the tablets. Doing so can release the drug too quickly, increasing the risk of side effects. Take this medication with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this drug.
The dosage is based on your medical condition and response to treatment. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or take this drug more often than directed. For ongoing conditions such as arthritis, continue taking this medication as directed by your doctor.
For certain conditions (such as arthritis), it may take up to two weeks of taking this drug regularly until you get the full benefit.
Tell your doctor if your condition does not improve or if it worsens.

Upset stomach, nausea, heartburn, headache, drowsiness, or dizziness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
This medication may raise your blood pressure. Check your blood pressure regularly and tell your doctor if the results are high.
Tell your doctor right away if you have any serious side effects, including: easy bruising/bleeding, difficult/painful swallowing, hearing changes (such as ringing in the ears), mental/mood changes, signs of kidney problems (such as change in the amount of urine), unexplained stiff neck, vision changes, symptoms of heart failure (such as swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).
Before taking naproxen, tell your doctor or pharmacist if you are allergic to it; or to aspirin or other NSAIDs (such as ibuprofen, celecoxib); or if you have any other allergies.

Kidney problems can sometimes occur with the use of NSAID medications, including naproxen. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have a change in the amount of urine.
