Frequently asked questions

What is Dilosyn Expectorant used for?

The Dilosyn Expectorant is a multi-symptom medicine used to provide relief from a productive cough (a "chesty" cough with mucus). It is commonly prescribed for coughs associated with the common cold, bronchitis, and other respiratory allergies.

Will Dilosyn Expectorant make me drowsy?

Yes. One of the main ingredients in Dilosyn Expectorant, methdilazine, is an antihistamine that is known to cause drowsiness and sleepiness. Because of this, it is best to avoid activities that require full mental alertness, like driving or operating heavy machinery, until you know how this medicine affects you.

Can I use Dilosyn Expectorant for a dry, hacking cough?

No. Dilosyn Expectorant is specifically formulated for a productive cough where there is mucus. The expectorant ingredients in the medicine, ammonium chloride and sodium citrate, help clear mucus from your lungs. For a dry cough without phlegm, a different type of cough medicine would be more appropriate.

I have been told to drink more water with my cough. Why is that important with Dilosyn Expectorant?

Drinking plenty of fluids, especially water, is very important when taking Dilosyn Expectorant. The extra fluid helps the expectorant ingredients work more effectively by thinning out the mucus even further, which makes it much easier for you to clear from your chest, and lubricates your throat.

How quickly will Dilosyn Expectorant start to work on my cough?

You should start to feel some relief from throat irritation and a reduction in your cough reflex within about 30 to 60 minutes of taking Dilosyn Expectorant. The full expectorant effect, which helps to loosen mucus, may take longer to become noticeable.
