Interactions between your drugs
dextromethorphan linezolid
Applies to: Dynatuss EX (dextromethorphan / guaifenesin / phenylephrine) and linezolid
Using dextromethorphan together with linezolid can increase the risk of a rare but serious condition called the serotonin syndrome, which may include symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, blurred vision, muscle spasm or stiffness, tremor, incoordination, stomach cramp, nausea, vomiting, and diarrhea. Severe cases may result in coma and even death. You should seek immediate medical attention if you experience these symptoms during treatment. Talk to your doctor if you have any questions or concerns. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Do not take any over-the-counter cough and cold medicine without consulting with a healthcare professional or checking the label first, as these products may contain dextromethorphan and may interact similarly with linezolid. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
phenylephrine linezolid
Applies to: Dynatuss EX (dextromethorphan / guaifenesin / phenylephrine) and linezolid
Using phenylephrine together with linezolid can increase your blood pressure. Contact your doctor if you experience increased side effects or if your condition changes. You may need a dose adjustment or need your blood pressure and heart rate checked more often if you use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Drug and food interactions
linezolid food
Applies to: linezolid
During and within two weeks after treatment with linezolid, you must not consume any foods or beverages that are high in tyramine content. Doing so can raise your blood pressure to dangerous levels, a condition known as hypertensive crisis. The condition is potentially fatal and may cause symptoms such as severe headache, confusion, blurred vision, problems with speech or balance, nausea, vomiting, chest pain, convulsions, and sudden numbness or weakness (especially on one side of the body). You should seek immediate medical attention if you have any of these symptoms. Foods that are high in tyramine include, but are not limited to, air dried meats; aged or fermented meats; sausage or salami; pickled herring; anchovies; liver; red wine; beer; aged cheeses, including blue, brick, brie, cheddar, parmesan, romano, and swiss; sour cream; sauerkraut; canned figs; raisins; bananas or avocados (particularly if overripe); soy beans; soy sauce; tofu; miso soup; bean curd; fava beans; or yeast extracts (such as Marmite). You should avoid the use of alcohol while being treated with linezolid, as alcohol may increase some of the nervous system side effects such as dizziness, drowsiness, and difficulty concentrating. Also avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
dextromethorphan food
Applies to: Dynatuss EX (dextromethorphan / guaifenesin / phenylephrine)
Alcohol can increase the nervous system side effects of dextromethorphan such as dizziness, drowsiness, and difficulty concentrating. Some people may also experience impairment in thinking and judgment. You should avoid or limit the use of alcohol while being treated with dextromethorphan. Do not use more than the recommended dose of dextromethorphan, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. Talk to your doctor or pharmacist if you have any questions or concerns.
phenylephrine food
Applies to: Dynatuss EX (dextromethorphan / guaifenesin / phenylephrine)
Both phenylephrine and caffeine can increase blood pressure and heart rate, and combining them may enhance these effects. Talk to your doctor before using these medications, especially if you have a history of high blood pressure or heart disease. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
