guaifenesin ER

If you have a cough that's caused by cigarette smoke, a cough that's linked to a breathing problem (e.g., asthma, emphysema), or a cough with a lot of mucus, let your primary care provider or pulmonologist know before taking guaifenesin ER. You might need more medical attention.

Please talk with your primary care provider if your cough gets worse, comes back after clearing up, or lasts more than a week. Also, let them know if you also have a rash, fever, or headache. These might be signs of a more serious medical condition that can't be treated with guaifenesin ER.

Keep in mind that many over-the-counter cough, cold, and flu medications contain similar ingredients, and it's best to avoid taking medications with overlapping ingredients. Always check with your care team before taking multiple over-the-counter cough, cold, and flu medications to make sure they're safe for you to take together.

Swallow guaifenesin ER tablets whole with a full glass of water. This will help to break up the mucus in your lungs. Don't crush, break, or chew the tablets since it can change how guaifenesin ER works.

Store guaifenesin ER up and away and out of children's reach and sight. Always put medication away every time you use it. This prevents them from accidentally swallowing any medication that was left out. If you think that your child might’ve accidentally swallowed guaifenesin ER, call a Poison Center at 1-800-222-1222 right away even if you aren't completely sure.

Don't give guaifenesin ER to a child under 12 years old. Check in with their pediatrician if guaifenesin IR is a good option for your child. Your child's healthcare team might also recommend home remedies, such as using a clean humidifier or cool mist vaporizer at home.
