Monoamine Oxidase Inhibitors (MAOI) do an excellent job at preventing the oxidase from destroying the neurotransmitters, but it can create some potentially dangerous side effects as well. You can't take this drug with some over the counter cold medicines or with certain foods.
Here is a small list of monoamine oxidase inhibitors names and the type of medication it's commonly found in. Amphetamine and dextroamphetamine used to treat ADHD. Eye drops with decongestants, Isometheptene found in Migranal, Meperidine found in Demerol, Methylphenidate which is Ritalin, Naphazoline and Oxymetazoline found in nasal sprays, phenylephrine is a decongestant found in cold products and Pseudoephedrine which is a nasal decongestant.
If you or someone you know is taking an MAOI as an antidepressant or for any other reason, please read the labels before taking any other medications as it could be fatal to combine two or more of these inhibitors at the same time.
