Drituss G (Oral)

Guaifenesin helps clear mucus or phlegm (pronounced flem) from the chest when you have congestion due to a cold or flu. It works by thinning the mucus or phlegm in the lungs.

This medicine is available both over-the-counter (OTC) and with your doctor's prescription.

Do not give any over-the-counter (OTC) cough and cold medicine to a baby or child under 4 years of age. Using these medicines in very young children might cause serious or possibly life-threatening side effects.

If your cough has not gotten better after 7 days or if you have a fever, skin rash, ongoing headache, or sore throat along with the cough, talk to your doctor. These symptoms could indicate other medical issues.

In deciding to use a medicine, you and your doctor need to think about the risks of taking the medicine compared to the benefits it may provide. For this medicine, consider the following:

Allergies

Inform your doctor if you have ever had any unusual or allergic reactions to this medicine or any other medicines. Also, let your healthcare professional know about any other types of allergies, like to foods, dyes, preservatives, or animals. For non-prescription products, carefully read the label or package ingredients.

Pediatric

There is no specific information comparing the use of guaifenesin in children to other age groups, but it is not expected to cause different side effects or problems in children than in adults. However, check with your doctor before using this medicine in children who have a chronic cough, like with asthma, or who have an unusually large amount of mucus or phlegm with their cough. Children with these conditions may need a different kind of medicine. Additionally, guaifenesin should not be given to children and infants younger than 2 years of age unless your doctor instructs you to do so.

Do not give any over-the-counter (OTC) cough and cold medicine to a baby or child under 4 years of age. Using these medicines in very young children could cause serious or possibly life-threatening side effects.

Geriatric

Many medicines have not been specifically studied in older individuals. Therefore, it may not be clear whether they work the same way in older people as they do in younger adults. Although there is no specific information comparing the use of guaifenesin in the elderly to other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.

Breast Feeding

There are no adequate studies in women to determine the risk to infants when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with Medicines

While some medicines should not be used together at all, in other cases, two different medicines may be used together even if an interaction might happen. In these situations, your doctor may want to adjust the dose, or other precautions may be necessary. Inform your healthcare professional if you are taking any other prescription or nonprescription (over-the-counter [OTC]) medicine.

Interactions with Food/Tobacco/Alcohol

Certain medicines should not be used around the time of eating food or certain types of food because interactions may occur. Using alcohol or tobacco with certain medicines may also lead to interactions. Discuss with your healthcare professional the use of your medicine with food, alcohol, or tobacco.
