Side effects are all of a drug’s effects besides its main effect. In most cases, drug manufacturers are aware of a drug’s side effects before it is released to the public. This information is included in pharmacies’ drug information handouts, and should be included with your prescription. Side effects are different from risk factors, in that risk factors are typically more rare and serious, and they often appear with extended use of a drug.

Allergic Reaction to Vioxx

Vioxx contains sulfur, a common allergen. Although Vioxx is not technically considered a sulfonamide drug, those with an allergy to sulfa drugs should not take any medication containing sulfur, due to the risk of allergic reaction. This drug may also cause an allergic reaction in patients with a sensitivity to codeine, hydrocodone, dihydrocodeine, or oxycodone.

Symptoms of an allergic reaction include:

• rash
• hives
• trouble breathing
• swelling of the throat, mouth, and/or tongue
