Drug Overview

Alka-Seltzer PLUS® is a medication designed to provide fast relief from the symptoms of severe cold and flu. It comes in convenient mix-in packets with a pleasant honey lemon zest flavor. This product contains several active ingredients: acetaminophen, which helps reduce pain and fever; phenylephrine HCl, a nasal decongestant that alleviates nasal congestion; dextromethorphan HBr, a cough suppressant; and guaifenesin, which acts as an expectorant to help loosen mucus in the airways.

By temporarily relieving symptoms such as minor aches and pains, headaches, sore throats, coughs, and nasal and sinus congestion, Alka-Seltzer PLUS® helps you feel more comfortable when you're under the weather. It also aids in reducing fever and thinning bronchial secretions, making it easier to clear mucus from your chest.

Uses

This medication is designed to help you feel better when you're dealing with a cold or flu. It temporarily relieves symptoms such as minor aches and pains, headaches, sore throats, coughs, and both nasal and sinus congestion. If you're struggling with mucus in your bronchial passages, this medication can also help loosen phlegm (a type of thick mucus) and thin bronchial secretions, making it easier to clear out bothersome mucus.

Additionally, it can temporarily reduce fever, helping you feel more comfortable as you recover.

Dosage and Administration

When using this medication, it's important to stick to the recommended dose to ensure your safety. For adults and children aged 12 years and older, you should dissolve the contents of one packet in 8 ounces of hot water. Make sure to sip the drink while it's still hot and finish it within 10 to 15 minutes. You can take this medication every 4 hours, but remember not to exceed 6 packets in a 24-hour period unless directed otherwise by your doctor.
