Asked by Samantha Gray, Oklahoma
I am a 26-year-old female. I have a diagnosis of bipolar disorder, PTSD, and anxiety. The doctor gave me samples of a transdermal patch called Emsam. What can you tell me about the medicine and possible side effects?

I am glad you asked this question, not just because people don't know much about Emsam, but also because Emsam is a member of a larger class of antidepressants called monoamine oxidase inhibitors, or MAOIs, which aren't used much anymore, but can be lifesaving for people who have failed to respond to other types of antidepressants.
Older antidepressants tend to have more bothersome side effects than the newer ones, which is mostly why the new ones were developed in the first place. MAOIs were especially challenging for patients, because in addition to causing "regular" side effects like insomnia, nausea and dry mouth, they also interacted with certain foods and medications in ways that can be lethal.
Because Emsam is a patch that delivers the MAOI selegiline through the skin, it avoids the medication passing through the stomach -- which was the danger area for problematic interactions with foods that contain a chemical called tyramine. This is Emsam's great advantage. At the lowest dose of 6 mg a day, people do not have to be careful about what they eat, which makes the drug much safer and easier to use. However, this is an important point: At higher doses of 9 or 12 mg a day, Emsam may interact dangerously with foods and so what one eats must be monitored.
Given all these troubles, it's reasonable to ask why anyone would bother using an MAOI nowadays, when there are so many newer and safer antidepressants available. Of course, the most straightforward reason is that some people don't respond to these newer medications and thus must turn to older antidepressants as the only available options. But anyone like me who has treated patients since the "old days" before Prozac could tell you plenty of stories of people who've had miraculous responses to an MAOI after failing with everything else. For this reason alone, a medication like Emsam is a welcome option.
MAOIs work especially well in people who have a lot of anxiety and who eat too much and sleep too much when they get depressed (as opposed to having insomnia and losing appetite). Given your combination of diagnoses, an MAOI is a very logical option for you.
A final point: Even though older medications like MAOIs and tricyclic antidepressants have more side effects than newer agents in general, people are really unique in their responses to these agents, for good or bad. I've treated plenty of patients who couldn't tolerate newer antidepressants but had no side effects whatsoever from one of the older antidepressants. This highlights how important it is not to give up on treating your depression, even when it comes time to reach for second-line options like MAOIs.
