What to Do If You Miss a Dose of Your Antidepressant

One missed antidepressant dose is usually not an emergency: take it when you remember the same day, or skip it if your next dose is near, and never double up. Check your label and ask your pharmacist.

The general rule for one missed dose

For most once-daily antidepressants, the usual approach is simple: if you remember within the same day, take the missed dose; if it is almost time for the next one, skip the missed dose and just take the next scheduled dose. The one thing to avoid is doubling up to make up for the gap, which can increase side effects without added benefit. Your specific medication's label is the final word, because timing varies by drug.

Why not to double up

Taking two doses close together raises the amount in your body at once and can worsen side effects such as nausea, jitteriness, or headache, without making the medication work better. Steady, even dosing is what keeps an antidepressant effective, so returning to your normal schedule after a single miss is almost always the right move.

What missing doses can feel like

Antidepressants are not addictive, but the body adjusts to a steady level, and stopping or repeatedly missing doses can cause discontinuation symptoms: dizziness, flu-like feelings, irritability, brief electric-shock sensations, or trouble sleeping. These are usually temporary and ease once the medication is resumed or, if you are stopping on purpose, tapered slowly with your prescriber. They are a reason to keep doses regular, not a sign of danger from one slip.

Building a routine that sticks

Most missed doses come down to memory, not motivation. Anchoring the dose to a daily habit, using a pill organizer, or setting a phone reminder helps. Steady routines and supportive people around you make consistency easier, the same stable, nurturing structure that supports well-being more broadly 1. If you find you are missing doses often, that is worth a candid conversation with your clinician rather than quiet frustration 2.

When a clinician helps

Your prescriber and pharmacist are the right people to give advice specific to your medication, since rules differ by drug and dose. A clinician can confirm what to do for repeated misses, rule out medical reasons you might be forgetting or feeling off, adjust the regimen to something easier to keep up with, and decide on a safe taper if you and they choose to stop. They can also pair medication with evidence-based therapy and check in on how you are doing overall. This kind of steady, relational follow-up is the backbone of good behavioral-health care 3. Never stop an antidepressant abruptly on your own; tapering is done with your prescriber.

Common questions

I missed last night's dose, what now?

If it's still the same day, take it when you remember. If your next dose is almost due, skip the missed one and continue normally. Don't take two at once. When unsure, check your label or ask your pharmacist.

Is one missed dose dangerous?

Usually not. A single miss rarely causes problems. Missing doses repeatedly can bring on temporary discontinuation symptoms, which is why a steady routine matters.

What if I keep forgetting?

Tell your clinician. They can simplify your regimen, suggest reminders or a pill organizer, and rule out other reasons. Frequent misses are a fixable problem worth raising.
