Medically reviewed by A Ras MD.
What is Emsam?
Emsam is a prescription medicine used to treat a certain type of depression called Major Depressive Disorder (MDD). Emsam belongs to the class of medicines known as monoamine oxidase inhibitors (MAOI). Emsam is a transdermal system (patch) you apply to your skin.
It is important to talk with your healthcare provider about the risks of treating depression and also the risk of not treating it. You should discuss all treatment choices with your healthcare provider.
Talk to your healthcare provider if you do not think that your condition is getting better with Emsam treatment.
Description
EMSAM® contains selegiline, a MAOI antidepressant. When applied to intact skin, EMSAM is designed to transdermally deliver selegiline over a 24-hour period.
Selegiline base is a colorless to yellow liquid, chemically described as (-)-(N)-Methyl-N-[(1R)-1-methyl-2-phenylethyl]prop-2-yn-1-amine. It has a molecular formula of C13H17N and a molecular weight of 187.30. The structural formula is:
EMSAM transdermal systems are available in three strengths that deliver approximately 6 mg, 9 mg, or 12 mg of selegiline over 24 hours. Each corresponding system has an active surface area of 20 cm2, 30 cm2, or 40 cm2 containing 20, 30, or 40 mg of selegiline, respectively. The composition of the systems per unit area is identical.
EMSAM is a matrix-type transdermal system composed of three layers as illustrated in Figure 1 below. Layer 1 is the Backing Film that provides occlusivity, physical integrity and protects the adhesive/drug layer. Layer 2 is the Adhesive/Drug Layer. Layer 3 consists of side-by-side release liners that are peeled off and discarded by the patient prior to applying EMSAM. The inactive ingredients are acrylic adhesive, ethylene vinyl acetate/polyethylene, polyester, polyurethane, and silicone coated polyester.

Mechanism of Action
The mechanism of action of selegiline (the drug substance of EMSAM) as an antidepressant is not fully understood, but is presumed to be linked to potentiation of monoamine neurotransmitter activity in the central nervous system (CNS) resulting from its irreversible inhibition of the enzyme monoamine oxidase (MAO).
What is the most important information I should know about Emsam?
1. Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, and young adults within the first few months of treatment.
2. Depression and other serious mental illnesses are the most important causes of suicidal thoughts and actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have or have a family history of bipolar illness (also called manic-depressive illness) or suicidal thoughts or actions. How can I watch for and try to prevent suicidal thoughts and actions?
- 1. Pay close attention to any changes, especially sudden changes in mood, behavior, thoughts, or feelings. This is very important when an antidepressant medicine is started or when the dose is changed.
- 2. Call the healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
- 3. Keep all follow-up visits with your healthcare provider as scheduled. Call the healthcare provider between visits as needed, especially if you have concerns about symptoms.
Call a healthcare provider right away if you have any of the following symptoms, especially if they are new, worse, or worry you:
- thoughts about suicide or dying
- attempts to commit suicide
- new or worse depression
- new or worse anxiety
- feeling agitated, restless, angry or irritable
- panic attacks
- trouble sleeping
- new or worse irritability
- acting aggressive, being angry or violent
- acting on dangerous impulses
- an extreme increase in activity or talking (mania)
- other unusual changes in behavior or mood
3. Emsam is not for children less than 12 years of age. Emsam may cause a severe increase in blood pressure in children less than 12 years of age.
Who should not use Emsam?

- selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine, sertraline, or paroxetine
- serotonin and norepinephrine reuptake inhibitors (SNRI) such as venlafaxine or duloxetine

Instructions for use
Step 1. Where to apply Emsam
- Place your Emsam transdermal system (patch) on one of the following areas (sites) on your body. See Figure A.
Figure A
- Emsam should be applied to dry, intact skin on the upper torso (below the neck and above the waist), upper thigh or the outer surface of the upper arm. Clothing and movement may make your patch rub off.
- Choose a new site each time you change your patch. Do not use the same site 2 days in a row.
Step 2. Before you apply Emsam
- Make sure the area on your skin where you apply your patch:
- is freshly washed with soap and warm water, then dried with a towel
- does not have any powder, oil or lotion
- does not have any cuts or irritation, including rashes, swelling, redness, or other skin problems
- is not hairy, scarred or calloused
Step 3. How to apply Emsam
- Remove Emsam from its sealed pouch by tearing at the notches (do not use scissors). Pull the pouch open. See Figure B.
Figure B
- Look at the patch to make sure it is not damaged. The patch should separate easily from the release liner. Throw away the patch if the release liner is hard to remove.
- Do not keep or store your Emsam outside of the sealed pouch. Do not cut your Emsam into smaller pieces.
- The Emsam patch has three layers. See Figures C and D.
Layers:- Release liner: The release liner is the layer that you remove before you put the patch on. See Figure C.
- Adhesive with medicine: The adhesive with medicine is the layer that sticks to your skin. See Figure C.
- Outside backing: The outside backing is the layer you see after you put the patch on your skin. See Figure D.
Figure C Figure D
- Apply the patch right away after you remove the patch from its sealed pouch.
- Hold the patch with the release liner facing you.
- Gently peel half of the release liner off the patch and throw it away. See Figure E.
Figure E
- Avoid touching the sticky side of the patch with your fingers. If you accidently touch the sticky side of the patch, wash your hands right away so the medicine does not go into the skin on your hands.
- Using the other half of the release liner as a handle, apply the sticky side of the patch to your selected area. See Figure F.
Figure F
- Hold an edge of the remaining half of the release liner and slowly peel it off. See Figure G.
Figure G
- After the release liner is removed, there should not be any adhesive sticking to the liner.
- Using your fingers and palm of your hand, press the entire patch firmly into place against your skin. See Figure H.
Figure H
- Make sure the patch firmly sticks to your skin.
- Gently rub the edges of your patch with your fingers to make sure the patch sticks to your skin.
- Wash your hands well with soap and water after you apply your patch to remove any medicine. Do not touch your eyes until after you have washed your hands.
- If the patch becomes loose, press it back in place. If your Emsam patch falls off, apply a new Emsam patch to a new site and follow your normal schedule for changing patches.
- If you forget to change your patch after 24 hours, remove the old patch. Put on a new patch in a different area and continue to follow your normal schedule for changing patches.
Step 4. Removing and disposing of your patch
- After 24 hours, remove your patch slowly and carefully to avoid damaging your skin.
- If the patch is too sticky on your skin and you need something to help you remove it:
- Gently wash the area with warm water and mild soap.
- A small amount of oil-based product (petroleum jelly, olive oil, or mineral oil) may be needed to help remove the patch. Gently apply and spread the oil underneath the patch edges.
- Apply an oil-based product or lotion to your skin if any adhesive (glue) remains after you remove your patch. This will gently loosen and remove any adhesive that is left over.
- If you still cannot easily remove the patch, ask your doctor or pharmacist about what to do for this problem.
- Fold the used Emsam patch in half and press it together firmly so that the sticky side sticks to itself.
- Safely throw away the folded patch in a container with a lid right away so that children and pets cannot reach it.
- Safely throw away any unused Emsam patches that are left over from the prescription as soon as they are no longer needed.
- To safely throw away the patches:
- Remove the leftover patches from their protective pouches and remove the release liners.
- Fold the patches in half with the sticky sides together and throw the patches away in a container with a lid.
- Wash your hands with soap and water.
