Pregnancy -

• For aspirin : Studies in humans have not shown that aspirin causes birth defects. However, aspirin has caused birth defects in animal studies.
  Some reports have suggested that too much use of aspirin late in pregnancy may cause a decrease in the newborn's weight and possible death of the fetus or newborn baby. However, the mothers in these reports had been taking much larger amounts of aspirin than are usually recommended. Studies of mothers taking aspirin in the doses that are usually recommended did not show these unwanted effects.
  Regular use of aspirin late in pregnancy may cause unwanted effects on the heart or blood flow in the fetus or in the newborn baby. Also, use of aspirin during the last 2 weeks of pregnancy may cause bleeding problems in the fetus before or during delivery or in the newborn baby. In addition, too much use of aspirin during the last 3 months of pregnancy may increase the length of pregnancy, prolong labor, cause other problems during delivery, or cause severe bleeding in the mother before, during, or after delivery. Do not take aspirin during the last 3 months of pregnancy unless it has been ordered by your doctor .
• For orphenadrine : Orphenadrine has not been reported to cause birth defects or other problems in humans.

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.

Other medicines - Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary.
