Known interactions between the following drugs: 4-Way Fast Acting, American Ginseng

Both American ginseng and phenylephrine, which may be included in non-prescription cold remedies, increase activity in the central nervous system (CNS). Stimulating the CNS may increase mental alertness and possibly physical performance, temporarily. However, too much CNS activity may increase the risk of unwanted effects, such as anger, confusion, insomnia, nausea, and restlessness. More serious results may include increased heart rate and high blood pressure. In general, American ginseng should not be taken at the same time as phenylephrine. Discuss this potential interaction with your healthcare provider at your next appointment, or sooner if you think you are having problems.
