Orphenadrine and Aspirin (Systemic)
In the U.S.-
Orphenadrine and aspirin ( or-FEN-a-dreen and AS-pir-in) combination is used to help relax certain muscles in your body and relieve the pain and discomfort caused by strains, sprains, or other injury to your muscles. However, this medicine does not take the place of rest, exercise, or other treatment that your doctor may recommend for your medical problem.
Orphenadrine acts in the central nervous system (CNS) to produce its muscle relaxant effects. Actions in the CNS may also be responsible for some of its side effects. Orphenadrine also has other actions (antimuscarinic) that may be responsible for some of its side effects.
This combination medicine also contains caffeine ( kaf-EEN) .
In the U.S., this combination medicine is available only with your doctor's prescription. In Canada, it is available without a prescription.

Before Using This Medicine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For orphenadrine and aspirin combination, the following should be considered:
Allergies- Tell your doctor if you have ever had any unusual or allergic reaction to orphenadrine, caffeine, aspirin or other salicylates including methyl salicylate (oil of wintergreen), or to any of the following medicines:
Also tell your health care professional if you are allergic to any other substances, such as foods, preservatives, or dyes.
Breast-feeding- This medicine has not been shown to cause problems in nursing babies. However, aspirin passes into the breast milk. Also, caffeine passes into the breast milk in small amounts. It is not known whether orphenadrine passes into the breast milk.
Children- Do not give a medicine containing aspirin to a child or a teenager with a fever or other symptoms of a virus infection, especially flu or chickenpox, without first discussing its use with your child's doctor . This is very important because aspirin may cause a serious illness called Reye's syndrome in children with fever caused by a virus infection, especially flu or chickenpox. Children who do not have a virus infection may also be more sensitive to the effects of aspirin, especially if they have a fever or have lost large amounts of body fluid because of vomiting, diarrhea, or sweating. This may increase the chance of side effects during treatment.
There is no specific information about the use of orphenadrine in children.
Older adults- Elderly people are especially sensitive to the effects of aspirin. This may increase the chance of side effects during treatment.
There is no specific information about the use of orphenadrine in the elderly.

In these cases, your doctor may want to change the dose, or other precautions may be necessary.
