My antidepressants aren’t working – what are my options?

You’ve taken the tablets. You’ve waited the weeks they told you to wait. You’ve gone back to your GP, tried a higher dose, maybe even switched to a different one entirely. And still something feels wrong. You’re not better. You might not even feel like yourself.

If this sounds familiar, you are not alone, and you are not imagining it. For a significant number of people in the UK, antidepressants don’t provide the relief they’re supposed to. That’s not a personal failing. It’s a clinical reality, and it’s why it helps to know about the alternatives to antidepressants available today.

This article explains what to do if antidepressants don’t work for you, why it happens, what the research actually shows, and what treatment options exist right now that you may not have been told about.

Antidepressants not working? Why it happens

Antidepressants are the most commonly prescribed treatment for depression in the UK. For many people, they are genuinely helpful. But they are not a universal solution.

One of the largest real-world antidepressant studies ever conducted, known as STAR*D, found that only around 28–33% of patients reached remission on their first antidepressant. That means roughly two thirds of people did not fully recover on their first prescription. When people who didn’t respond tried a second or third medication, the chances of remission fell with each step.

This pattern is common enough to have its own clinical name: treatment-resistant depression. It is usually defined as depression that has not responded adequately to at least two antidepressants at a therapeutic dose, taken for long enough. Estimates suggest around a third of people with depression do not respond adequately to standard treatments.

There are several reasons why antidepressants may not work for a given person.

Brain chemistry is individual

Antidepressants work by altering the balance of neurotransmitters like serotonin, noradrenaline and dopamine. But depression is not a single, uniform condition. Different people have different underlying profiles, and a medication that targets one pathway may not address what’s happening for you.

Side effects make continuation difficult

Weight gain, emotional blunting, sexual dysfunction, fatigue and nausea are among the most commonly reported antidepressant side effects. For many patients, the side effects become intolerable before the medication has had the chance to work, or the medication takes the edge off symptoms but leaves the person feeling less like themselves.

Reduced response over time

Some people find that antidepressants work initially but gradually become less effective. This is sometimes called antidepressant tachyphylaxis, or informally, “poop-out”. Increasing the dose or switching to a new medication can only go so far.

Medication may not reach the underlying problem

In many people with depression, brain imaging shows reduced activity in regions involved in mood regulation. For some, this pattern may not respond fully to medication alone, which is why approaches that work in a different way can help.

“Just surviving, not living”

Many of the patients who come to Tranquil TMS describe a feeling that will resonate with anyone who has been through this: the sense of just surviving rather than truly living. The medication may have taken the worst edges off the lows, but it hasn’t brought anything back: no joy, no energy, no sense of being present in your own life.

Others describe feeling emotionally numb. The depression itself is blunted, but so is everything else. There’s nothing to look forward to. Relationships feel distant. Work is something to get through.

This is not what recovery is supposed to look like. If this is where you are, it is worth knowing that there are evidence-based alternatives, not as a last resort, but as a medically recognised next step.

What are the alternatives to antidepressants?

There are several routes worth exploring, depending on your situation. They are not mutually exclusive, and in many cases they work best in combination. The right option should always be discussed with your doctor or a psychiatrist.

• Repetitive transcranial magnetic stimulation (rTMS). A non-invasive, medication-free treatment that works directly on the brain regions involved in mood regulation. It has been covered by NICE guidance (IPG542) for depression since 2015 and was endorsed by the Royal College of Psychiatrists in 2017. It avoids the body-wide side effects of medication, needs no anaesthetic, and you can drive yourself to and from each session. Read our guide to rTMS.
• Psychological treatments. Cognitive behavioural therapy (CBT) and other structured psychological approaches have a strong evidence base for depression. If you haven’t yet had access to a good course of CBT, this remains a valuable option. Like antidepressants, though, psychological approaches don’t work for everyone, particularly when depression is severe or longstanding.
• Lifestyle and supportive approaches. Exercise, sleep management and dietary changes can support recovery. These are valuable, but for people with moderate to severe depression they are rarely enough on their own.
• Mood stabilisers and augmentation strategies. Your psychiatrist may recommend adding lithium, an atypical antipsychotic or another medicine to your existing antidepressant. These approaches can be effective for some people but have their own side effects and require careful monitoring.
• Electroconvulsive therapy (ECT). ECT has a significant evidence base for severe, treatment-resistant depression. However, it requires a general anaesthetic and can cause memory side effects.

What is rTMS and how does it work?

rTMS (repetitive transcranial magnetic stimulation) uses carefully targeted magnetic pulses to stimulate specific areas of the brain. In depression, a region called the dorsolateral prefrontal cortex (DLPFC) is often underactive. rTMS delivers repeated pulses to this area, encouraging the nerve cells there to become more active and better connected.

Unlike antidepressants, which work throughout the body and brain, rTMS targets the neural circuits involved in mood. Because it works from a different angle, it can help some people whose depression has not responded to medication.

A standard course of rTMS involves sessions of around 20–30 minutes, five days a week, over four to six weeks. Accelerated protocols, such as theta burst stimulation, can be delivered over one to two weeks. You remain fully awake throughout. There is no sedation, no recovery period, and no impact on your ability to go about your normal day. You can read what TMS actually feels like in our patient guide.

You usually do not need to stop your current medication to begin rTMS; the two can normally be given alongside each other. Never stop or change medication without medical advice.

What does the evidence show?

Among the alternatives to antidepressants, rTMS has a substantial and growing evidence base for depression, including depression that has not responded to medication.

In our own published research, conducted across our patient cohort and published in the Journal of Psychiatry Depression & Anxiety in 2020, we recorded a response rate of 66.66% and a remission rate of 37.03%. Our more recent clinical audits show 66–76% of patients responding to a full course.

66.66% response rate (published study, 2018–19)

37.03% remission rate (published study, 2018–19)

Response usually means symptoms have reduced by at least half; remission means symptoms have reduced to a minimal level. These figures come from routine clinical practice rather than a controlled trial, and results vary from person to person.

Research elsewhere points the same way. A 2014 multisite study by Dunner and colleagues found that, for many patients who responded to TMS, the benefit was maintained over a 12-month follow-up. A 2023 study by Hutton, Aaronson and colleagues reported marked improvements in both depression and anxiety for patients with anxious depression treated with TMS in routine clinical settings.

Is rTMS right for me?

If you’re looking at alternatives to antidepressants, rTMS may be worth considering if one or more of the following applies to you:

• You would prefer a non-medication approach to treatment
• You have tried two or more antidepressants at therapeutic doses without adequate improvement
• You have had side effects from medication that stopped you continuing or reaching an effective dose
• You are currently on medication but feel it is not providing enough relief
• You have tried psychological treatments and found them helpful but not sufficient on their own

It is not suitable for everyone. People with certain metallic implants near the head, active seizure disorders or certain implanted devices may not be eligible. A full clinical assessment is completed before any treatment begins to make sure it is appropriate for you.

What to do if antidepressants don’t work

Antidepressants not working doesn’t mean you’ve run out of options. rTMS is a clinically recognised next step, covered by NICE guidance, that is available privately; in some cases NHS funding can be explored.
