Allergic Rhinitis and Decongestants
Read more about Decongestants.
Decongestants come in the form of pills or nasal sprays. Their job is to decrease congestion by constricting blood vessels.
Side Effects and Warnings
Possible side effects of decongestants include:
- Over-stimulation, such as nervousness and insomnia
- Raised blood pressure
- Rebound congestion—If these drugs are used for long periods of time, membranes get used to the effects, so that stopping the medication produces the swelling and congestion that was originally being treated. This is a common problem with nose drops and sprays.
