How to use Flemnil Liquid

Use this medicine in the dose and duration as advised by your doctor. Check the label for directions before use. Flemnil Liquid may be taken with or without food.

How Flemnil Liquid works

Guaifenesin, phenylephrine and bromhexine which relieve cold symptoms. Guaifenesin is an expectorant which decreases the stickiness of mucus (phlegm) and helps in its removal from the airways. Phenylephrine is a decongestant which narrows the small blood vessels providing relief from congestion or stuffiness in the nose. Bromhexine is a mucolytic which thins and loosens mucus (phlegm), making it easier to cough out.

Quick tips

  • Flemnil Liquid is prescribed to get relief from cough with mucus.
  • Drink warm water to help loosen the congestion and lubricate your throat while you are taking this medication.
  • Take exactly as directed by your doctor or on the label. Do not increase the dosage or take for longer than is recommended.
  • In general, most coughs do not last more than 2 weeks. If your cough does last longer than this, it's better to see your doctor.
  • Inform your doctor if you have a history of stomach ulcers or asthma.
