GUAIFENESIN/PHENYLEPHRINE - ORAL

PHONETIC PRONUNCIATION: (gweye-FEN-eh-sin/fen-ill-EFF-rin)

COMMON BRAND NAME(S): Endal, Numonyl, Sinupan

GENERIC NAME(S): guaifenesin/phenylephrine HCl

Uses

USES: This combination medication is used to temporarily treat cough and runny/stuffy nose (nasal congestion) caused by infections (such as the common cold), allergies (such as hay fever), and other breathing illnesses. This product is usually not used for ongoing cough from smoking or long-term breathing problems (such as chronic bronchitis, emphysema) unless directed by your doctor. Guaifenesin is an expectorant. It works by thinning and loosening mucus in the airways, clearing congestion, and making breathing easier. Phenylephrine is a decongestant (sympathomimetic). It reduces nasal congestion by narrowing the blood vessels in the nose. If you are self-treating with this medication, it is important to read the package instructions carefully before you start using this product to be sure it is right for you. (See also Precautions section.) Cough-and-cold products have not been shown to be safe or effective in children younger than 6 years. Therefore, do not use this product to treat cold symptoms in children younger than 6 years unless specifically directed by the doctor. Some products (such as long-acting tablets/capsules) are not recommended for use in children younger than 12 years. Ask your doctor or pharmacist for more details about using your product safely. These products do not cure or shorten the length of the common cold and may cause serious side effects. To decrease the risk for serious side effects, carefully follow all dosage directions. Do not give other cough-and-cold medication that might contain the same or similar ingredients (see also Drug Interactions section). Ask the doctor or pharmacist about other ways to relieve cough and cold symptoms (such as drinking enough fluids, using a humidifier or saline nose drops/spray).


How to use GUAIFENESIN/PHENYLEPHRINE - ORAL

HOW TO USE: Take this medication by mouth with or without food, as directed by your doctor. If you are self-treating, follow all directions on the product package. To prevent trouble sleeping, do not take this medication close to bedtime. If you are uncertain about any of the information, ask your doctor or pharmacist. Dosage is based on your age, medical condition, and response to treatment. Do not increase your dose or take this drug more often than directed. Guaifenesin may have a bitter taste. Swallow capsules and tablets whole. Scored tablets may be split for lower doses. Chewable tablets may be swallowed whole or chewed. Drink plenty of fluids while taking this medication. Fluids will help to break up mucus and clear congestion. If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose. If your liquid form is a suspension, shake the bottle well before each dose. Tell your doctor if your condition is accompanied by fever, severe sore throat, rash, persistent headache, or if it persists, returns, or worsens after 7 days. These may be signs of a serious medical problem. Seek immediate medical attention if you think you may have a serious medical problem.

Side Effects

SIDE EFFECTS: Nausea or headache may occur. If either of these effects persist or worsen, tell your doctor or pharmacist promptly.

Tell your doctor right away if any of these unlikely but serious side effects occur: dizziness, fainting, shaking (tremor), fast/irregular/pounding heartbeat, difficult/painful urination, mental/mood changes (such as confusion, nervousness, irritability), trouble sleeping, seizures.

DRUG INTERACTIONS: The effects of some drugs can change if you take other drugs or herbal products at the same time. This can increase your risk for serious side effects or may cause your medications not to work correctly. These drug interactions are possible, but do not always occur.
