What DEMAZIN COLD RELIEF is used for

DEMAZIN COLD RELIEF provides relief of upper respiratory congestion associated with common cold, nasal allergy, hayfever, and sinusitis.

DEMAZIN COLD RELIEF contains a combination of two medicines, an antihistamine and a decongestant.

Antihistamines help reduce allergic symptoms such as sneezing, runny or itchy nose, and burning or itchy eyes, by preventing the effects of a substance called histamine.

Histamine is produced by the body in response to foreign substances which the body is allergic to.

Decongestants produce narrowing of blood vessels. This leads to clearing of stuffy or blocked noses.

Your doctor or pharmacist, however, may have given you DEMAZIN COLD RELIEF for another purpose.

Ask your doctor or pharmacist if you have any questions about why this medicine has been given to you.

DEMAZIN COLD RELIEF can be used in adults and children.
