Drug Interactions between phenelzine and Simuc-HD
This report displays the potential drug interactions for the following 2 drugs:
- phenelzine
- Simuc-HD (guaifenesin/hydrocodone/phenylephrine)
Interactions between your drugs
phenylephrine phenelzine
Applies to: Simuc-HD (guaifenesin / hydrocodone / phenylephrine) and phenelzine
Using phenelzine together with phenylephrine is not recommended. Combining these medications can cause dangerously high blood pressure and even death. You may use phenylephrine only after you have been off phenelzine for at least 14 days. You should seek immediate medical attention if you experience sudden and severe headache, blurred vision, confusion, seizures, chest pain, nausea or vomiting, sudden numbness or weakness (especially on one side of the body), speech difficulties, fever, sweating, lightheadedness, and/or fainting during treatment with phenelzine, as these may be signs and symptoms of excessively high blood pressure. 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.
phenelzine HYDROcodone
Applies to: phenelzine and Simuc-HD (guaifenesin / hydrocodone / phenylephrine)
Using HYDROcodone together with phenelzine may rarely increase the risk of serious side effects such as respiratory depression, low blood pressure, fainting, coma, and even death. In general, it is best to wait at least 14 days after stopping phenelzine before you start treatment with HYDROcodone. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. You should avoid the use of alcohol while being treated with these medications. Also avoid driving or operating hazardous machinery until you know how your medications affect you, and do not exceed the dosage or frequency of use prescribed by your doctor. 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
phenelzine food
Applies to: phenelzine
During and within two weeks after treatment with phenelzine, 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 phenelzine, 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.
HYDROcodone food
Applies to: Simuc-HD (guaifenesin / hydrocodone / phenylephrine)
Do not use alcohol or medications that contain alcohol while you are receiving treatment with HYDROcodone. This may increase nervous system side effects such as drowsiness, dizziness, lightheadedness, difficulty concentrating, and impairment in thinking and judgment. In severe cases, low blood pressure, respiratory distress, fainting, coma, or even death may occur. If you are taking certain long-acting formulations of hydrocodone, consumption of alcohol may also cause rapid release of the drug, resulting in high blood levels that may be potentially lethal. Likewise, you should avoid consuming grapefruit and grapefruit juice, as this may increase the blood levels and effects of hydrocodone. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed. Do not use more than the recommended dose of HYDROcodone, and avoid activities requiring mental alertness such as driving or operating hazardous machinery until you know how the medication affects you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medication without first talking to your doctor.
phenylephrine food
Applies to: Simuc-HD (guaifenesin / hydrocodone / 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.
