Starting an antidepressant takes patience, and the waiting is hard when you already feel worn down. Some people quietly wonder if the medication is helping at all but do not want to seem impatient or ungrateful. That question is fair and worth asking out loud. Knowing what a working medication should feel like, and by when, makes it easier to have a useful conversation with your prescriber.
First, give it a fair trial
Antidepressants such as SSRIs and SNRIs do not work like a painkiller. They usually take four to eight weeks at an adequate dose to show their full effect. Early on, you might notice sleep or appetite shift before your mood does. Some side effects that show up in the first week or two, like mild nausea or restlessness, often settle down. So a couple of tough days does not mean the medication has failed. A fair trial means an adequate dose taken consistently for roughly six to eight weeks.
Signs it may not be working well enough
After you have given it that fair trial, these are common signs the current plan is not enough:
- Your core symptoms - low mood, loss of interest, heavy fatigue, hopelessness - are basically unchanged from before you started.
- You feel slightly better but still cannot function the way you need to at work, at home, or in relationships.
- You had some improvement that faded and has not come back after several weeks.
- Side effects are strong enough that you are tempted to stop taking it.
- Your sleep, appetite, or concentration are still clearly disrupted.
None of these mean you did anything wrong. They are simply information your prescriber needs.
What the next step usually looks like
If the first medication has not helped enough, a clinician has several well-established moves. Often they will adjust the dose, switch to a different antidepressant, or add a second medication that works alongside the first. It is completely normal to try more than one before finding a good fit. This is trial and adjustment, not failure.
There is also a specific term for what you may be experiencing. When depression has not improved enough after adequate trials of two or more antidepressants, clinicians call it treatment-resistant depression. Roughly a third of people with depression fall into this group at some point. It is common, it is not a character flaw, and importantly it points toward a different kind of treatment rather than simply another pill.
When to ask about advanced options
If you have honestly worked through therapy and more than one antidepressant without lasting relief, it is reasonable to ask your doctor directly about treatments designed for this situation. Two of the most established are TMS (transcranial magnetic stimulation), a non-invasive, FDA-cleared treatment that uses magnetic pulses to stimulate mood-related areas of the brain, and esketamine (Spravato), an FDA-approved nasal spray given under medical supervision in a certified clinic. Both work differently from standard pills, which is exactly why they can help some people who have not responded to those. Our guide comparing TMS and esketamine walks through how they differ.
How to raise it with your prescriber
You do not need perfect medical language. A few honest sentences do the job: how long you have taken the medication, at what dose, what has and has not changed, and what daily life still looks like. Then ask two direct questions: what would we try next, and at what point would you refer me to a specialist? A good clinician welcomes that conversation.

The honest bottom line
An antidepressant that is not working is not the end of the road. It is one data point that helps your care team find the next, better step. The most powerful thing you can do is name it clearly to a doctor you trust and keep moving toward the option that fits. A doctor's recommendation is what moves most people to finally act, so that one conversation matters more than it may feel like it does.
