What is a common reason why decongestants should be used with caution?

Using decongestants with caution is important primarily because they can potentially exacerbate hypertension. Decongestants work by narrowing blood vessels to reduce swelling and congestion in the nasal passages. However, this vasoconstrictive effect can also increase blood pressure. For individuals who already have high blood pressure or underlying cardiovascular issues, using these medications without proper caution can lead to significant health risks.

This concern is particularly relevant for those who are older or have a history of heart disease. Monitoring blood pressure and consulting with a healthcare provider before using decongestants is crucial to ensure safety. While interactions with antidepressants, sedation, and liver damage are important considerations for other medications, they do not represent the primary concern associated with decongestant use, especially regarding their common application in treating congestion.
