What is Covonia Night Time Formula?

Covonia Night Time Formula is a form of treatment that works to reduce the symptoms of cough at night time, to help restore normal sleeping patterns. The active ingredients that help to relieve the effects of a cough are:

  • Diphenhydramine
  • Dextromethorphan

Diphenhydramine is an antihistamine that can treat the symptoms of an allergic reaction, as well as cold symptoms and also help with sleeping difficulties. Dextromethorphan is a cough suppressant that also helps to relieve irritation in the throat.


What are the symptoms of a cold?

When someone gets a cold, the effects don’t appear straight away and take some time before becoming their worst. The symptoms that are caused by a cold include:

  • Sneezing
  • Coughing

Many treatments will be able to work on relieving several symptoms. Also, not all symptoms will be visible when having a cold. Therefore, finding the right treatment for you is important or getting relief as soon as possible.
