If you have missed applying your selegiline patch, the correct action depends on timing. Apply a new patch as soon as you remember, unless it is almost time for your next scheduled dose. If that is the case, you should skip the missed dose entirely and apply your next patch at the regular time. Never apply two patches at once to make up for a missed dose.
The primary goal when managing a missed selegiline patch is to safely return to your regular 24-hour schedule. This means prioritizing a consistent medication level and strictly avoiding the dangerous practice of doubling the dose to "catch up."

The Core Principle: Maintaining a Steady State
Why Consistency Is Key
The selegiline transdermal patch is designed to deliver a specific, controlled amount of medication through your skin over a 24-hour period.
This steady delivery maintains a stable therapeutic level of the drug in your bloodstream. Consistency is crucial for the medication to work effectively while minimizing the risk of side effects.
The "As Soon As Possible" Rule
Applying a new patch as soon as you remember is the standard recommendation because it minimizes the duration your body goes without the intended dose.
This action helps re-establish the therapeutic level of medication and gets you back on your treatment plan with the least possible disruption.
The "Skip the Dose" Exception
The crucial exception to this rule is when it's already close to the time for your next scheduled patch.
Applying a patch very late and then putting on the next one on schedule just a few hours later would create a significant overlap. This can cause a sudden, unsafe spike in the medication level in your system. In this situation, forgoing the missed dose is the safest way to return to your normal schedule.
Understanding the Risks: Why You Should Never Double Up
The Danger of Overdose
Applying an extra patch to make up for a missed one is equivalent to taking a double dose of a potent medication. This fundamentally overrides the controlled-release mechanism of the patch.
Selegiline is a Monoamine Oxidase Inhibitor (MAOI). Exposing your system to an excessive amount can lead to serious adverse effects.
Risk of Hypertensive Crisis
One of the most significant risks of too much selegiline is a hypertensive crisis—a sudden, dangerously high spike in blood pressure.
While the patch formulation is designed to reduce this risk compared to oral MAOIs, an overdose from using two patches at once dramatically increases this potential danger.
The Importance of the 24-Hour Cycle
Each patch is carefully calibrated to last for 24 hours. Attempting to compensate for a missed dose by using two patches disrupts this entire system. The safest and most effective path is always to return to the prescribed one-patch-per-day schedule as smoothly as possible.
A Simple Action Plan for a Missed Dose
Here is a clear guide to follow based on your situation.
- If you remembered a few hours late: Remove the old patch (if you forgot) and apply a new one immediately. Plan to apply your next patch at its usual, regularly scheduled time the following day.
- If it's nearly time for your next scheduled dose: Do not apply a late patch. Skip the missed dose completely, remove the old patch, and simply apply your next patch at the normal time.
- If you are ever unsure what to do: Do not guess. The safest course of action is to contact your prescribing doctor or pharmacist for guidance specific to your health profile.
Following these rules ensures you can safely manage your treatment and maintain the consistency required for it to be effective.
Summary Table:
| Situation | Action | Key Reason |
|---|---|---|
| Remembered a few hours late | Apply a new patch immediately. Next dose at regular time. | Minimizes time without medication; re-establishes steady levels. |
| Almost time for next dose | Skip the missed dose. Apply next patch at the normal time. | Prevents dangerous medication overlap and overdose risk. |
| Never | Apply two patches at once. | Avoids a dangerous spike in medication levels (hypertensive crisis risk). |
