Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to medicines in this group or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Very young children are usually more sensitive to the effects of this medicine. Increases in blood pressure, nightmares, unusual excitement, nervousness, restlessness, or irritability may be more likely to occur in children. Also, mental changes may be more likely to occur in young children taking these combination medicines.

Do not give any over-the-counter (OTC) cough and cold medicine to a baby or child under 4 years of age. Using these medicines in very young children might cause serious or possibly life-threatening side effects .

Before giving any of these combination medicines to a child, check the package label very carefully. Some of these medicines are too strong for use in children. If you are not certain whether a specific product can be given to a child, or if you have any questions about the amount to give, check with your health care professional.

Do not give aspirin or other salicylates to a child or teenager with a fever or other symptoms of a virus infection, especially flu or chickenpox, without first discussing their use with your child's doctor. This is very important because salicylates may cause a serious illness called Reye's syndrome in children and teenagers with fever caused by a virus infection, especially flu or chickenpox. Also, children may be more sensitive to the aspirin or other salicylates contained in some of these medicines, especially if they have a fever or have lost large amounts of body fluid because of vomiting, diarrhea, or sweating.

Geriatric

The elderly are usually more sensitive to the effects of this medicine. Confusion, difficult or painful urination, dizziness, drowsiness, feeling faint, or dryness of mouth, nose, or throat may be more likely to occur in elderly patients. Also, nightmares or unusual excitement, nervousness, restlessness, or irritability may be more likely to occur in the elderly.

Pregnancy

The occasional use of antihistamine, decongestant, and analgesic combinations is not likely to cause problems in the fetus or in the newborn baby. However, when these medicines are used at higher doses and/or for a long time, the chance that problems might occur may increase. For the individual ingredients of these combinations, the following apply:

  • Acetaminophen—Acetaminophen has not been shown to cause birth defects or other problems in humans. However, studies on birth defects have not been done in humans.
  • Alcohol—Some of these combination medicines contain large amounts of alcohol. Too much use of alcohol during pregnancy may cause birth defects.
  • Antihistamines—Antihistamines have not been shown to cause problems in humans.
  • Caffeine—Studies in humans have not shown that caffeine causes birth defects. However, studies in animals have shown that caffeine causes birth defects when given in very large doses (amounts equal to the amount of caffeine contained in 12 to 24 cups of coffee a day).
  • Phenylephrine—Studies on birth defects have not been done in either humans or animals with phenylephrine.
  • Pseudoephedrine—Studies on birth defects with pseudoephedrine have not been done in humans. In animal studies pseudoephedrine did not cause birth defects but did cause a decrease in average weight, length, and rate of bone formation in the animal fetus when administered in high doses.
  • Salicylates (e.g., aspirin)—Salicylates have not been shown to cause birth defects in humans. Studies on birth defects in humans have been done with aspirin. However, salicylates have been shown to cause birth defects in animals.

Regular use of salicylates late in pregnancy may cause unwanted effects on the heart or blood flow in the fetus or newborn baby. Use of salicylates during the last 2 weeks of pregnancy may cause bleeding problems in the fetus before or during delivery, or in the newborn baby. Also, too much use of salicylates 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.

Breastfeeding

If you are breast-feeding the chance that problems might occur depends on the ingredients of the combination. For the individual ingredients of these combinations, the following apply:

  • Acetaminophen—Acetaminophen passes into the breast milk. However, it has not been shown to cause problems in nursing babies.
  • Alcohol—Alcohol passes into the breast milk. However, the amount of alcohol in recommended doses of this medicine does not usually cause problems in nursing babies.
  • Antihistamines—Use is not recommended since the chances are greater for this medicine to cause side effects, such as unusual excitement or irritability, in the nursing baby. Also, since antihistamines tend to decrease the secretions of the body, it is possible that the flow of breast milk may be reduced in some women.
  • Caffeine—Small amounts of caffeine pass into the breast milk and may build up in the nursing baby. However, the amount of caffeine in recommended doses of this medicine does not usually cause problems in nursing babies.
  • Decongestants (e.g., phenylephrine, pseudoephedrine)—Decongestants may pass into the breast milk and may cause unwanted effects in nursing babies of mothers taking this medicine.
  • Salicylates (e.g., aspirin)—Salicylates pass into the breast milk. Although salicylates have not been reported to cause problems in nursing babies, it is possible that problems may occur if large amounts are taken regularly.<
