Naprosyn or Naproxen

Other Names: Anaprox

Why is this drug prescribed?
Naproxen relieves the pain, redness, inflammation, swelling and stiffness caused by certain types of arthritis, including gout. It also is used to treat muscle aches, menstrual pain, headaches, and pain after surgery, dental work and childbirth.

When should it be used?
Naproxen usually is taken twice a day (morning and evening) for arthritis, every eight hours for gout attacks, and every six to eight hours for pain (including menstrual pain). Follow the instructions on your prescription label, and ask your pharmacist to explain any part that you do not understand. Although arthritis symptoms usually improve within two weeks, you may have to take this drug regularly for four weeks before feeling its full effect. Relief from gout attacks may occur in 24 to 48 hours.

How should it be used?
Naproxen comes in tablets. Your prescription label tells you how much to take at each dose. Ask your pharmacist any questions you have about refilling your prescription.

What special instructions should I follow while using this drug?
Naproxen can affect mental alertness and coordination. Do not drive a car or operate dangerous machinery until you know how it affects you. Take only the amount of medication prescribed. If you think you need more to relieve your symptoms, contact us. We may adjust your dose.

What should I do if I forget to take a dose?
Take the missed dose as soon as you remember it, but if you remember a missed dose near the time you are to take the next dose, take only the scheduled dose. Do not take a double dose.

What side effects can this drug cause? What can I do about them?

  • Constipation, abdominal pain, nausea, heartburn
    Take this medication with meals, milk, or a magnesium and aluminum hydroxide antacid (e.g., Maalox). Do not drink alcoholic beverages.
  • Skin rash or ringing in the ears
    Contact your doctor.
  • Drowsiness, dizziness or headache
    Contact your doctor if the effects persistent or are severe.

What other precautions should I follow while using this drug?
Before you take Naproxen, tell us what prescription and nonprescription drugs you are taking, especially anticoagulants ("blood thinners") such as Warfarin, aspirin, other arthritis medications, Probenecid, and diuretics ("water pills"). Tell us if you ever had gastritis or bleeding from the stomach or rectum, ulcers, diverticulitis, kidney disease, heart disease or high blood pressure. Women who are pregnant or breast-feeding should inform their doctors. If you ever had a bad reaction to aspirin or arthritis medications, tell us before taking Naproxen. Do not take aspirin while taking Naproxen unless directed to do so. Do not allow anyone else to take this medication.
