If you are taking Naprosyn on a regular basis, you should take it at the same time(s) every day.
Common side effects of Naprosyn include stomach pain, heartburn, nausea, and gas. Naprosyn can aslo cause dizziness or drowsiness. Do not drive or operate heavy machinery until you know how this medication will affect you.

Appropriate studies have not been performed on the relationship of age to the effects of naproxen controlled-release tablets in the pediatric population. Safety and efficacy have not been established.
Appropriate studies have not been performed on the relationship of age to the effects of naproxen delayed release tablets, suspension, and tablets in children younger than 2 years of age. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of naproxen in the elderly. However, elderly patients may be more sensitive to the effects of naproxen than younger adults, and are more likely to have age-related kidney or stomach problems, which may require caution and an adjustment in the dose for patients receiving naproxen.

What is the most important information I should know about medicines called Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?
NSAID medicines may increase the chance of a heart attack or stroke that can lead to death. This chance increases:
- with longer use of NSAID medicines
- in people who have heart disease
NSAID medicines should never be used right before or after a heart surgery called a “coronary artery bypass graft (CABG).”
NSAID medicines can cause ulcers and bleeding in the stomach and intestines at any time during treatment. Ulcers and bleeding:
- can happen without warning symptoms
- may cause death
The chance of a person getting an ulcer or bleeding increases with:
- taking medicines called “corticosteroids” and “anticoagulants”
- longer use
- drinking alcohol
- older age
- having poor health
NSAID medicines should only be used:
- exactly as prescribed
- at the lowest dose possible for your treatment
- for the shortest time needed
What are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)?
NSAID medicines are used to treat pain and redness, swelling, and heat (inflammation) from medical conditions such as:
- different types of arthritis

Who should not take a Non-Steroidal Anti-Inflammatory Drug (NSAID)?
Do not take an NSAID medicine:
- if you had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID medicine
- for pain right before or after heart bypass surgery
Tell your healthcare provider:
- about all of your medical conditions.
- about all of the medicines you take. NSAIDs and some other medicines can interact with each other and cause serious side effects. Keep a list of your medicines to show to your healthcare provider and pharmacist.
- if you are pregnant. NSAID medicines should not be used by pregnant women late in their pregnancy.
- if you are breastfeeding. Talk to your doctor.

What happens if I miss a dose?
Since Naprosyn is sometimes used only when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What should I avoid while taking Naprosyn?
Avoid drinking alcohol. It may increase your risk of stomach bleeding.
Avoid taking aspirin while you are taking Naprosyn.
Ask your doctor before taking any other medication for pain, arthritis, fever, or swelling. Many medicines available over the counter contain aspirin, salicylates, or other medicines similar to naproxen (such as ibuprofen or ketoprofen). Taking certain products together can cause you to get too much of this type of medication.
Ask your doctor before using an antacid, and use only the type your doctor recommends. Some antacids can make it harder for your body to absorb naproxen.
