What is the most important information I should know about TREXIMET?

1. TREXIMET may increase your chance of a heart attack or stroke that can lead to death. TREXIMET contains 2 medicines: sumatriptan and naproxen sodium (a nonsteroidal anti-inflammatory drug [NSAID]).

Your chance of a heart attack or stroke increases:

with longer use of NSAID medicines
if you have heart disease.

2. TREXIMET should never be used right before or after a heart surgery called a coronary artery bypass graft (CABG).

3. TREXIMET can cause ulcers and bleeding in the stomach and intestines at any time during your treatment.

Ulcers and bleeding:

Risk factors for heart disease include:

high cholesterol levels
family history of heart disease
female who has gone through menopause
male over age 40.

5. “Serotonin syndrome” is a serious and life-threatening problem that may occur with TREXIMET, especially if used with antidepressant medicines called selective serotonin reuptake inhibitors (SSRIs) or selective norepinephrine reuptake inhibitors (SNRIs).

Commonly used SSRIs are:

CELEXA ® (citalopram HBr)
LEXAPRO ® (escitalopram oxalate)
PAXIL ® (paroxetine)
PROZAC ®/SARAFEM ® (fluoxetine)

ZOLOFT ® (sertraline)
LUVOX ® (fluvoxamine).

changes in blood pressure
high body temperature or sweating
tight muscles

6. TREXIMET should only be used:

exactly as prescribed
at the lowest dose possible for your treatment
for the shortest time needed.

7. TREXIMET already contains an NSAID (naproxen). Do not use TREXIMET with other medicines to lessen pain or fever without talking to your healthcare provider first, because they may contain an NSAID also.
