A dry and hacking cough, especially during your sleep is something that can haunt you for days. Thankfully, Robitussin (on sale here) a drug made by Pfizer is cough syrup that helps alleviate both a cough and the resultant phlegm that comes with it.

1. Allfen
2. Altarussin
3. Amibid LA
4. Balminyl
5. Resyl
6. Mucinex

How Robitussin Works

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. Robitussin 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.

Robitussin Side Effects

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

– Dizziness

The recommended dose is 600mg for adults. Do not take Robitussin if you’re pregnant before speaking to your doctor.
