Flowtuss oral

This medication is used by adults to treat cough caused by the common cold. This product contains 2 medications: guaifenesin and hydrocodone. Guaifenesin is an expectorant. It works by thinning and loosening mucus in the airways. Hydrocodone is a narcotic cough suppressant (antitussive) that affects a certain part of the brain, reducing the urge to cough.

This product is not used for ongoing cough from smoking or long-term breathing problems (such as chronic bronchitis, emphysema, asthma) unless directed by your doctor.

How to use Flowtuss

Read the Medication Guide provided by your pharmacist before you start taking guaifenesin/hydrocodone and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food, as directed by your doctor, usually every 4 to 6 hours. Do not take more than 6 doses in a 24-hour period. If you have nausea, it may help to take this drug with food. Ask your doctor or pharmacist about other ways to decrease nausea (such as lying down for 1 to 2 hours with as little head movement as possible).

Carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.

Drink plenty of fluids while you are taking this medication unless otherwise directed by your doctor. The fluid will help loosen the mucus in your lungs.

Do not increase your dose or use this product more often or for longer than prescribed. Your condition will not improve any faster, and your risk of side effects will increase.

To prevent withdrawal reactions, your doctor may reduce your dose gradually. Consult your doctor or pharmacist for more details, and report any withdrawal reactions right away.

When this medication is used for a long time, it may not work as well. Talk with your doctor if this medication stops working well.
