  • Orally Ingested Tablets

Decongestants are commonly recommended for people affected by hay fever and other seasonal allergies. They are available in any pharmacy without a prescription.

What Causes Congestion?

The cause of nasal congestion is the expansion of blood vessels in the nose due to inflammation. Decongestants treat these blood vessels by shrinking them back to their normal size, enabling you to breathe properly.

Decongestants come into contact with the adrenergic receptor. Stimulating these receptors changes the flow of blood from the expanded blood vessels. These changes in blood flow shrink the vessels back to their original position.


Decongestants are good treatments for viruses, minor congestion, allergies, and common cold problems. Many types can start taking effect within 10 minutes, but others can take up to an hour to kick in.

Interference With Other Medications

If you are taking other medicines for treating cold and flu, it is strongly advised to stop taking a decongestant. There are similar active ingredients in these medicines; consumption of more than one such ingredient at a time will exceed the required dosage and can result in negative side effects.

People who SHOULD NOT Take Decongestants:

  • People suffering from high blood pressure
  • Women who breastfeed their newborn
  • People with heart disease
  • Men with prostate problems
  • Pregnant women or those who are trying to get pregnant
  • People who have diabetes
  • People with kidney problems

Because decongestants work by affecting blood flow, many people have conditions in which taking a decongestant could have an adverse effect.

These components can interact negatively with your normal bodily functions. If the wrong mediciation is taken, it can result in severe reactions.
