Slight drowsiness/dizziness, nausea, or vomiting may occur. Rarely, some people may experience severe drowsiness/dizziness with normal doses. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Delsym is a very reliable brand. It is straight to the point about how long this medicine remains effective which is 12 hours a day. You only have to take this twice in 1 day unlike other cough medicines that make you take it every 4-6 hours. It relieves you from coughing and it tastes better then other cough syrup.

Most voted positive review A persistent cough cleared up almost immediately, and I have recommended it ever since. We have used it in my family, & I always buy it for my friends with coughs that just won't quit. I could not recommend Delsym any higher and am thankful for all of the sl...

Taking certain MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking isocarboxazid, metaxalone, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, or tranylcypromine during treatment with this medication.

Check the medication label if you have phenylketonuria (PKU). You should not use dextromethorphan if you are allergic to it. Dextromethorphan should not be given to a child younger than 12 years old. Ask a doctor before using this medicine if you are pregnant or breast-feeding.

Dextromethorphan can be found in many over-the-counter medications, so make sure you read package labels carefully. Don't use multiple products with dextromethorphan. Taking too much dextromethorphan can cause serious side effects, such as fast heartbeat, slow breathing, confusion, or seizures.

What medication should I take if I have a cough or experiencing congestion? Over-the-counter medication, such as guaifenesin (Mucinex), pseudoephedrine (Sudafed) and dextromethorphan (Robitussin and Delsym), can help alleviate these symptoms.

Talk to your provider first before using dextromethorphan (Delsym) if you're taking or have recently taken medications for Parkinson's disease or depression known as monoamine oxidase inhibitors (MAOIs). These medications can sometimes interact with dextromethorphan (Delsym) and cause dangerously high blood pressure.

It may increase your risk of liver damage. Ask a doctor or pharmacist before using any other medicine that may contain dextromethorphan or acetaminophen (sometimes abbreviated as APAP). Taking too much acetaminophen can lead to a fatal overdose.

A product that contains only an expectorant (like guaifenesin for chest congestion) and a cough suppressant (like dextromethorphan) may work best. You don't need a product containing acetaminophen, as it's typically used to treat pain, like a sore throat or headache, or to help lower a fever.
