Answer:
Oral nasal descongestant for cold symptoms can temporarily relieve nasal congestion, but also slightly raise blood pressure during their usage.
Explanation:
The spikes in blood preasure are especially caused by decongestants containing the ingredient pseudoephedrine. This happens because they're more readily absorbed into the bloodstream. If you suffer from hypertension you should ask to your doctor. They may recommend that you take a regular (short-acting) form of pseudoephedrine rather than extended-release products. Check always the ingredients from descongestant products.
