Generic Name: chlorpheniramine/guaifenesin/pseudoephedrine (klor-fen-EER-a-meen/gwye-FEN-e-sin/sue-do-eh-FED-rin)
Brand Name: Lemohist Plus
Lemohist Plus is used for:
Relieving symptoms of sinus congestion, runny nose, sneezing, and throat and airway irritation due to colds, upper respiratory infections, and allergies. It may also be used for other conditions as determined by your doctor.
Lemohist Plus is a decongestant, antihistamine, and expectorant combination. It works by constricting blood vessels and reducing swelling in the nasal passages, making it easier to breathe. The antihistamine works by blocking the action of histamine, which helps reduce symptoms, such as watery eyes and sneezing, while the expectorant loosens mucus and lung secretions in the chest and makes coughs more productive.

- you are allergic to any ingredient in Lemohist Plus

- you are unable to urinate or are having an asthma attack
- you take sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days
