Does Naproxen Interact with other Drugs or Food?

• Furosemide (Lasix)
• Lithium
• Methotrexate
• Warfarin (coumadin)

Are There Other Risks?
Naproxen can cause stomach ulcers that bleed. The chance of
this serious problem increases the longer you take naproxen and
with higher doses of naproxen. Stomach bleeding can also
happen suddenly while you take naproxen. Stop taking naproxen
and call your healthcare provider right away if you get:
• A burning stomach pain
• Black bowel movements that look like tar
• Vomit that looks like blood or coffee grounds

Allergic reactions: Naproxen can cause serious allergic
reactions, including asthma-like symptoms (problems breathing,
swallowing, and wheezing) and rash.
Liver damage: Stop taking naproxen and tell your doctor right
away if you have nausea, vomiting, tiredness, loss of appetite,
itching, yellow coloring of skin or eyes, flu-like symptoms, and
dark urine.
Kidney problems: Naproxen can cause serious kidney problems,
including sudden kidney failure or worsening of kidney problems
that you already have.
Fluid retention: Naproxen can cause fluid retention (holding of
water in your body) and swelling. Fluid retention can be a serious
problem if you have high blood pressure or heart failure.
Pregnancy: Do not take naproxen during your last 3 months of
pregnancy because it may cause problems in the unborn child or
complications during delivery. Tell your doctor if you are
pregnant or planning to become pregnant
Breast-feeding: Tell your doctor if you are breast-feeding.

How Do I Take Naproxen?
When taking an over-the-counter naproxen product, 1 tablet (220
mg) should be taken every 8 to 12 hours while symptoms last.
You may take 2 tablets within the first hour of symptoms for the
first dose. However, you should not exceed 2 tablets (440 mg) in
any 8 to 12 hour period or 3 tablets (660 mg) in a 24-hour period.
If your healthcare provider has prescribed naproxen to you, you
should take it according to their directions.
