ROBITUSSIN Cough Relief – Dosage & Side Effects



A dry and hacking cough, especially during your sleep is something that can haunt you for days. Robitussin, a drug made by Pfizer is a cough relief product (syrup, tablets, gel caps) for adults and children, that includes a narcotic and an expectorant. It helps alleviate both a cough and the phlegm that comes with it.


Along with this chesty cough comes the production of thick mucous by the lungs as they attempt to clear the cold by producing biomaterial which attacks the virus by way of phagocytosis and cell apoptosis. While this is a great way of protecting the body, this phlegmy mucous can cause distress to the sick person. This cough relief product goes to work by thinning this mucous so it’s easily eliminated by way of coughing or spitting. At the same time, it soothes the irritated lining of the respiratory tract, helping you get some much needed rest and a good night’s sleep.


Some of the side effects you can expect from this expectorant include:

  • Dizziness
  • Drowsiness (Robitussin makes you sleepy)
  • Rash
  • Diarrhea
  • Dry mouth
  • Nausea
  • Upset stomach
  • Headaches


The recommended dose is 600mg for adults (original version). Do not take Robitussin if you’re pregnant before speaking to your doctor. This cough medicine also comes in tablets; swallow it whole with water since crushing it into a fine powder may reduce its efficacy. Store your medication in a cool, dry place, and speak to your doctor should your cough not abate after 7 days.
