Antidepressant Selection Tool
Find Your Best Antidepressant Match
Answer a few questions about your priorities to see which antidepressant might work best for you.
Key Takeaways
- Emsam delivers selegiline through the skin, avoiding the oral route and its dietary restrictions.
- Compared with common oral antidepressants, Emsam shows similar efficacy but a slower onset.
- Side‑effect profile is distinct: skin irritation is common, while sexual dysfunction is less frequent than with SSRIs.
- Cost and insurance coverage vary widely; generic oral selegiline is cheaper but lacks the transdermal advantage.
- Best suited for patients who struggle with pill fatigue, have mild‑to‑moderate depression, and can manage patch changes.
What Is Emsam (Selegiline)?
When treating depression, Emsam is a transdermal patch that delivers the MAO‑B inhibitor selegiline. Originally approved for Parkinson’s disease in the 1980s, a lower‑dose version (6 mg/24 h) received FDA clearance for major depressive disorder (MDD) in 2006. The patch releases a steady amount of drug through the skin, bypassing first‑pass metabolism and allowing lower systemic concentrations.
How Emsam Works
The active ingredient, Selegiline is a selective monoamine oxidase‑B (MAO‑B) inhibitor, which prevents the breakdown of dopamine, norepinephrine, and, at higher doses, serotonin. By increasing these neurotransmitters, mood improves. Because the patch delivers only a modest dose, dietary tyramine restrictions-required with older MAO‑A inhibitors-are largely unnecessary, reducing the risk of hypertensive crises.
When Is Emsam Prescribed?
Emsam is indicated for adults with major depressive disorder who have not responded adequately to at least one oral antidepressant. Clinicians also consider it for patients who prefer a non‑oral route, have swallowing difficulties, or experience gastrointestinal side effects from pills. Off‑label, some neurologists use higher‑dose patches for Parkinson’s symptoms, but that’s beyond the scope of this comparison.
Alternative Antidepressant Options
Before diving into a side‑by‑side comparison, it helps to group the main alternatives:
- SSRIs Selective serotonin reuptake inhibitors such as sertraline, fluoxetine, and citalopram
- SNRIs Serotonin‑norepinephrine reuptake inhibitors like venlafaxine and duloxetine
- Bupropion A norepinephrine‑dopamine reuptake inhibitor (NDRI) marketed as Wellbutrin
- Mirtazapine A noradrenergic and specific serotonergic antidepressant (NaSSA) known for its sedating effect

Efficacy and Onset of Action
Large‑scale phase‑III trials (N=1,300) showed that the 6 mg/24 h patch achieved a mean 5‑point reduction on the Hamilton Depression Rating Scale after 8 weeks, matching the effect size of sertraline in head‑to‑head studies. However, patients report feeling the “full benefit” a bit later, usually around week 3‑4, because the drug builds up in the skin layers before systemic levels stabilize.
Side‑Effect Profile and Safety
Skin irritation is the hallmark of the patch; about one‑in‑five users experience redness or itching at the application site. Importantly, sexual dysfunction-which plagues up to 30% of SSRI users-is reported in fewer than 5% of Emsam patients, making it attractive for younger adults concerned about libido.
Serious adverse events are rare. The low‑dose patch does not require the tyramine‑restricted diet that older MAO‑A inhibitors demand. Yet clinicians must still watch for serotonin syndrome when combining Emsam with other serotonergic drugs (e.g., tramadol, triptans).
Drug Interactions and Dietary Considerations
Because Emsam partially inhibits MAO‑B, adding an SSRI or SNRI can tip the balance toward excessive serotonin. The recommended washout period is 14 days when switching from an MAO‑B inhibitor to a serotonergic antidepressant, and vice‑versa. Over‑the‑counter cold remedies containing decongestants (pseudoephedrine) should also be used with caution, as they can raise blood pressure when combined with MAO‑B inhibition.
Practical Considerations: Cost, Insurance, and Adherence
In the United States, the brand‑name Emsam patch carries a retail price of roughly $275 per month. Some insurers classify it as a specialty drug, leading to higher co‑pays. Generic patches (available in Canada and the EU) drop the price to about $150. In contrast, generic SSRIs can be as cheap as $10‑$15 per month, making them the first‑line economic choice.
From an adherence perspective, a weekly patch eliminates the daily pill burden, which can improve compliance for patients with busy lifestyles or memory issues. However, patients must be comfortable with applying a medical adhesive and rotating sites to avoid skin irritation.
Who Should Choose Emsam?
Ideal candidates include:
- Adults with mild‑to‑moderate MDD who have tried at least one oral antidepressant without sufficient relief.
- Patients who experience sexual side effects on SSRIs or SNRIs.
- Individuals who prefer a non‑oral format due to swallowing difficulties or gastrointestinal intolerance.
- Those who can manage weekly patch changes and monitor for skin reactions.
Conversely, patients with severe dermatological conditions, high risk of hypertension, or who are taking multiple serotonergic agents may be better served by a traditional oral medication.
Bottom Line
Emsam offers a unique delivery method that sidesteps many oral‑drug pitfalls, especially the dreaded sexual dysfunction of SSRIs. Its efficacy is on par with first‑line agents, but the trade‑off is higher cost and the need to watch for skin irritation and specific drug interactions. When the weekly patch fits a patient’s lifestyle and budget, it can be a compelling alternative to standard oral antidepressants.
Frequently Asked Questions
How does Emsam differ from oral selegiline?
Oral selegiline is prescribed at much higher doses (10‑30 mg) for Parkinson’s disease and requires strict tyramine avoidance. The 6 mg/24 h patch releases a low dose that avoids dietary restrictions and focuses on depression treatment.
Can I use Emsam with an SSRI?
Combining them raises the risk of serotonin syndrome. If a switch is needed, a 14‑day washout period is recommended before starting the new agent.
What should I do if the patch irritates my skin?
Rotate application sites, keep the area clean and dry, and consider using a hypoallergenic barrier film. If irritation persists beyond a week, contact your prescriber for an alternative.
Is Emsam covered by Medicare?
Medicare Part D may cover it, but coverage varies by plan. Check your specific formulary for co‑pay amounts and any prior‑authorization requirements.
How long can I stay on Emsam?
Unlike short‑term anxiolytics, Emsam can be used long‑term as long as the patient remains stable and no serious side effects emerge. Routine follow‑up every 3‑6 months is advised.

October 26, 2025 AT 14:37When budgeting, consider that generic SSRIs can be as low as ten dollars a month, while the brand Emsam patch often exceeds two hundred dollars.

October 28, 2025 AT 11:03While the transdermal delivery system offers convenience, it is essential to recognize the pharmacodynamic implications of MAO‑B inhibition combined with serotonergic agents. The low‑dose formulation still exerts enough enzymatic blockade to potentiate serotonin levels when co‑administered with SSRIs or SNRIs, raising a legitimate concern for serotonin syndrome. This risk is not merely theoretical; case reports have documented hypertensive spikes and neuromuscular hyperactivity in patients who failed to observe the recommended fourteen‑day washout period. Moreover, the interaction with over‑the‑counter decongestants such as pseudoephedrine can precipitate a sympathetic surge, potentially endangering patients with undiagnosed hypertension. Clinicians must also be vigilant about the additive effect on norepinephrine when combining Emsam with bupropion, as this may exacerbate anxiety or trigger arrhythmic events. The patch’s propensity for dermatologic irritation, though often mild, may lead to secondary infection if the site is not properly cleaned and rotated. From a metabolic standpoint, the steady‑state plasma levels achieved by transdermal delivery bypass first‑pass hepatic metabolism, which can be advantageous for patients with liver impairment but also means that drug clearance is highly dependent on skin perfusion and patient adherence to the replacement schedule. Lastly, insurance formularies frequently categorize the patch as a specialty medication, resulting in higher out‑of‑pocket costs that can compromise long‑term compliance. Therefore, while Emsam presents a viable alternative for select patients, prescribers should conduct a comprehensive risk‑benefit assessment, educate patients thoroughly on washout protocols, and monitor for signs of serotonin excess or cardiovascular instability throughout treatment.
