Dr. Chrysoula I. Liakou MD, PhD
- Treated online: Yes, usually. OCD is assessed by video with structured questions; first-line treatment is CBT with exposure and response prevention (ERP), with an SSRI added after full assessment when needed. Controlled medicines are never prescribed online.
- What it is: unwanted intrusive thoughts, images or urges (obsessions) that cause distress, and repeated actions or mental rituals (compulsions) done to relieve it; it affects about 1 to 2% of people and usually starts in the teens or early adulthood.
- Intrusive thoughts: symptoms, not intentions; they stick precisely because they attack what you care about most, and the distress they cause is evidence against intent, not for it.
- When to get help: when obsessions or compulsions take up more than an hour a day, or interfere with work, relationships or daily life.
- Treatment timelines: ERP therapy usually runs 12 to 20 sessions; an SSRI for OCD builds benefit over 8 to 12 weeks, often at a higher dose than for depression, and continues for at least a year before a planned, gradual stop.
- Emergency: call 112 if you are having thoughts of ending your life, or if OCD sits alongside deep depression and you might act on such thoughts.
Intrusive thoughts in OCD are symptoms, not intentions, and they do not make you dangerous. But if you are having thoughts of ending your life, or OCD sits alongside deep depression and you might act on those thoughts, use the crisis information in the red box lower on this page instead of waiting for any appointment.
Can an online doctor treat OCD?
Often, yes. A video consultation can often provide enough information to assess obsessive-compulsive disorder: the doctor uses structured questions about obsessions, compulsions and the time they consume, then arranges the two evidence-based treatments, CBT with exposure and response prevention, and SSRI medication where appropriate.[1] Severe or housebound OCD needs specialist services.
How an online consultation helps with OCD
- A structured assessment, without the waiting list: The doctor maps your obsessions and compulsions with the same kind of questions used in specialist clinics, grades severity by the hours lost and the distress caused, and tells you what the picture means.
- A route into ERP therapy: Exposure and response prevention is the psychological treatment with the strongest evidence for OCD.[1] The doctor explains it properly and refers you, rather than leaving you to search alone.
- Straight answers on medication: What SSRIs realistically do for OCD, why doses are often higher and timelines longer than for depression, and what the first weeks feel like, all before anything is prescribed.
- Privacy that lowers the barrier: Many people have never said their obsessions out loud. Saying them from your own home, to a doctor who has heard the themes many times, is often the step that unlocks everything else.
What are the symptoms of OCD?
Obsessive-compulsive disorder has two linked parts: obsessions, which are unwanted intrusive thoughts, images or urges that cause real distress, and compulsions, which are the rituals, mental or physical, performed to neutralise that distress.[2] The relief is brief, the loop strengthens, and rituals gradually consume more time and territory.
- Fear of contamination, with washing or cleaning rituals
- Doubt about locks, appliances or harm, with repeated checking
- Intrusive violent, sexual or blasphemous images that horrify you
- Fear of harming someone by accident or carelessness
- A need for symmetry, order or things feeling “just right”
- Counting, repeating words or actions, or mental reviewing
- Repeatedly seeking reassurance from people close to you
- Avoiding places, objects or people that trigger the thoughts
Intrusive thoughts do not mean you are dangerous
This is the fact that keeps most people from seeking help, so it is worth stating plainly: almost everyone has occasional intrusive thoughts, including violent and taboo ones. In OCD the thoughts stick precisely because they attack what you care about most. A gentle person gets images of harming someone; a devoted parent gets unbearable doubts about their child’s safety; a religious person gets blasphemous intrusions. The horror you feel is evidence of your values, not your intentions, and clinicians treating OCD understand this distinction well.[2] You will not shock the doctor, and you do not have to describe every thought in detail for the assessment to work; naming the theme is enough.
Compulsions you cannot see
Not all rituals are visible. Mental compulsions, such as reviewing conversations for proof you did nothing wrong, silently repeating phrases, or scanning your own reactions for evidence about what kind of person you are, count just as much as washing and checking. So does reassurance-seeking, including hours of internet searching. People with mostly mental rituals often go years believing they “just worry a lot”, while the disorder quietly takes over. If your mind runs neutralising routines, tell the doctor; it changes nothing about your suitability for treatment and everything about how well the plan fits.
When should I see a doctor about OCD?
See a doctor when obsessions or compulsions take up more than an hour a day, cause real distress, or interfere with work, relationships or daily routines.[1] Many people live with OCD for years before asking for help, often out of shame about the thoughts, and the condition rarely fades on its own once the loop is established.
Earlier is genuinely easier: the less territory the rituals hold, the less there is to win back. And if your family has been drawn into the rituals, answering the same question nightly, or waiting while checks are completed, that is a common sign the OCD is running the household schedule, not a reason for anyone to feel blamed.
Which OCD treatment might the doctor recommend?
Treatment follows how much of your day the disorder occupies and how deep the distress runs. This is the decision framework the doctors use, aligned with European and UK guidance:[1]

| Presentation | Likely first step | Suitable for online care? | When referral or in-person care is needed |
|---|---|---|---|
| Obsessions and rituals under an hour a day, life mostly on track | Guided self-help based on CBT principles, with a booked review | Usually yes | If rituals expand, or self-help stalls after a fair trial |
| OCD taking more than an hour a day, or driving avoidance and reassurance loops | Referral for CBT with ERP; an SSRI after full assessment when appropriate | Usually yes | Little response after adequate courses of therapy and medication: psychiatry review |
| Severe OCD: hours lost daily, housebound, or work and care breaking down | Specialist assessment, usually combining intensive ERP and medication | Assessment and referral | Specialist or intensive services are the standard pathway[1] |
| OCD alongside significant depression | Both assessed together; safety first, then a combined plan | Often yes | Deep depression or any safety concern moves care in person |
| Thoughts of ending your life, or beliefs held with total conviction | Crisis support or psychiatric assessment today | No: urgent care comes first | Call 112 in an emergency, or find your national crisis helpline at findahelpline.com |

See available times →How does ERP therapy work?
Exposure and response prevention works by breaking the link between the intrusive thought and the ritual. With a therapist, you deliberately approach a feared trigger, touching a door handle, leaving the house without re-checking the stove, and then resist the compulsion that usually follows. Anxiety rises, peaks and falls on its own, and your brain gradually learns the catastrophe does not arrive.[2]
Done properly, ERP is graded and collaborative: you build a ladder from mildly uncomfortable steps to harder ones, and nothing is sprung on you. It is the psychological treatment with the strongest evidence for OCD, recommended as first-line in European and UK guidance,[1][5] and it also treats the invisible forms: for mental rituals and reassurance loops, the “response” being prevented is the mental review or the asking, not a wash or a check. Therapy is typically weekly for a set number of sessions, increasingly available by video in many countries, and hard work in the way physiotherapy is hard work: uncomfortable, structured and effective. The consultation’s job is to get you into it with a clear referral and a doctor keeping oversight, rather than leaving the search to you.
What the doctor checks in an online OCD consultation
You do not need a rehearsed speech. “I check things for hours and I am tired of it” or “I have thoughts I hate” is a fine opening. Behind the conversation, the assessment is structured. The doctor will typically check:
- Obsessions and their themes: contamination, harm, doubt, symmetry, unwanted sexual or religious intrusions, named at whatever level of detail you are comfortable with.
- Compulsions, visible and mental: washing, checking, ordering, counting, mental reviewing and reassurance-seeking, and how firmly each is wired to a fear.
- Time and territory: hours per day, what is being avoided, how work, study and family life are holding up, and who else has been recruited into rituals.
- Insight: whether you recognise the thoughts as products of OCD; beliefs held with complete conviction change the referral pathway.
- Mood and safety: depression commonly travels with OCD, so mood, sleep and any thoughts of self-harm are asked about plainly.
- Lookalikes and history: conditions that can be confused with OCD, including body-focused repetitive behaviours, health anxiety, tic disorders and autistic routines, plus previous treatment, medicines, pregnancy and breastfeeding.
By the end, the doctor has graded severity, distinguished OCD from its lookalikes as far as video allows, and agreed the next step with you. The limits are stated just as plainly: diagnostic uncertainty, very severe illness and absent insight are referred onward rather than stretched into an online plan.
Treatment options for obsessive-compulsive disorder
What you can do yourself
Self-help has a real place early on, provided it points the right way. Reading solid material on how OCD works often brings the first relief, because the disorder feels much less monstrous once named. Practising “delay and shrink”, postponing a ritual by five minutes and doing it once rather than five times, builds the same muscle ERP trains. Telling one trusted person reduces the isolation that OCD feeds on. Two things reliably make OCD worse: reassurance-seeking, because every answer feeds the doubt that demanded it, and avoidance, because it confirms the danger. Alcohol quietly amplifies both anxiety and low mood, and if stress is stoking the loops, it is worth addressing in its own right; the page on stress and health covers practical tools. Self-help alone suits milder OCD; when rituals hold more than an hour a day, treatment works better than willpower.
Prescription treatment
A prescription is never issued without a consultation. When medication is right, the usual choice is an SSRI such as sertraline, fluoxetine or escitalopram, and OCD has its own honest arithmetic: effective doses are often higher than those used for depression, benefit builds slowly over 8–12 weeks rather than arriving in a fortnight, and treatment that works is usually continued for at least a year before any planned, gradual stop.[1][3][4] The first one to two weeks can bring nausea, jitteriness or disturbed sleep before benefit appears, which is why an early review is booked rather than hoped for. SSRIs are not addictive, and combining medication with ERP generally beats either alone for moderate and severe OCD.[1] If an adequate trial brings little change, the doctor adjusts the dose, switches, or refers to psychiatry, where options such as clomipramine are managed with closer monitoring. Controlled medicines are not prescribed online, and no sedative treats OCD anyway. If you are pregnant, breastfeeding or planning pregnancy, say so: treatment continues to be possible, chosen case by case.
When OCD is treated online, and when you need in-person care
Treated online: assessment and diagnosis of suspected OCD; mild to moderate OCD, with guided self-help or referral into CBT with ERP; SSRI starts with early booked reviews, dose adjustments and planned, gradual stopping; OCD tangled with anxiety, low mood or broken sleep, managed in one plan; and restarts of treatment that worked before.
In-person care: severe or housebound OCD goes to specialist or intensive services, with the referral written for you rather than left as advice; OCD with absent insight, suspected psychosis or significant safety concerns goes to psychiatry or urgent care; children and teenagers need local child and adolescent services; and hoarding, body dysmorphic concerns and tic disorders are signposted to the right specialist pathway when they emerge from the assessment, because they respond to differently targeted treatment.[1] After any referral, the doctor remains available to review medication and keep the plan moving while you wait for therapy to begin. OCD also keeps close company with anxiety disorders and depression, and treating those alongside is part of the work, not a distraction from it.
When to get in-person care
Get urgent, in-person help today if depression alongside OCD has deepened to thoughts of ending your life, if you have harmed yourself, if you have stopped eating or drinking, or if beliefs have crossed from doubt into fixed conviction that others insist is not real. If you have seriously harmed yourself or taken an overdose, call 112 now.
If you are having thoughts of harming yourself, call 112 in an emergency. You can also find your national crisis helpline at findahelpline.com. You do not have to wait for an appointment.

Frequently asked questions about obsessive-compulsive disorder
What is OCD?
Obsessive-compulsive disorder (OCD) is a mental health condition with two parts: obsessions, which are unwanted, intrusive thoughts, images or urges that cause intense anxiety or disgust, and compulsions, which are repeated actions or mental rituals done to neutralise the distress. Common themes are contamination, harm, checking, symmetry and unwanted sexual or religious thoughts. OCD affects about 1 to 2% of people and is treatable.
What are the symptoms of OCD?
OCD symptoms include intrusive thoughts that return however hard you push them away, intense anxiety or a sense that something is wrong until a ritual is done, repeated washing, checking, counting, ordering or asking for reassurance, mental rituals such as reviewing or praying, avoidance of triggers, and hours lost each day. Most people with OCD know the thoughts are irrational, which makes them no less distressing.
What causes OCD, and is it genetic?
OCD has no single cause. It runs in families, so genes contribute, and differences in the brain circuits that handle doubt and threat play a part. Stressful or traumatic events, perfectionism, a tendency to feel overly responsible, and in some children a streptococcal infection can trigger or worsen it. OCD is not caused by weakness or by the content of the thoughts.
Is OCD just being tidy or liking things organised?
No. Liking order is a preference; OCD is unwanted thoughts and rituals that consume time, cause real distress and interfere with life. Many people with OCD are not tidy at all, and the popular use of the word hides how disabling and how treatable the condition is.
Are intrusive thoughts a sign that I am dangerous?
No. Intrusive thoughts are near-universal, and in OCD they stick precisely because they clash with your values; the distress they cause is evidence against intent, not for it. OCD is not a risk of acting on the thoughts. Thoughts of harming yourself are different and need urgent help: call 112 if you might act on them.
Do I have to describe my intrusive thoughts in detail?
No. Naming the theme of your OCD, such as contamination, harm or unwanted images, is enough for assessment. Doctors who assess OCD have heard every theme many times and will not judge you. Detail can wait until therapy, where it is shared at a pace you control, because the content matters less than the pattern.
What is ERP therapy, and does it work?
Exposure and response prevention (ERP) is a form of CBT for OCD in which you gradually face triggers while resisting the ritual, so the brain relearns that the feared outcome does not arrive and the anxiety falls on its own. It is the psychological treatment with the strongest evidence for OCD: most people who complete a course of 12 to 20 sessions improve substantially.
Can an online doctor prescribe OCD medication in Europe?
Where clinically appropriate, yes. After a full video assessment of your OCD, the doctor may prescribe an SSRI and will book early reviews, because OCD often needs higher doses and longer timelines than depression. Controlled medicines are not prescribed online, and medication works best combined with ERP.
How long do SSRIs take to work for OCD?
Longer than most people expect: benefit in OCD typically builds over 8 to 12 weeks, doses often end up higher than those used for depression, and treatment that works is usually continued for at least a year before a planned, gradual stop. Early side effects such as nausea or restlessness usually settle within the first two weeks.
Can OCD be cured, and how long does it last?
Untreated OCD tends to be long-term, waxing and waning with stress. With ERP, medication or both, most people reduce their OCD symptoms substantially and many reach a point where it no longer limits their life; some become symptom-free. Relapses can happen under stress and respond to a return to the ERP techniques, which is why therapy ends with a relapse plan.
What can I do myself to manage OCD?
Self-help for OCD means practising the ERP principle: notice the urge, delay or shrink the ritual, and let the anxiety fall without neutralising it; stop asking others for reassurance, which feeds the loop; treat intrusive thoughts as noise rather than messages; and keep sleep, exercise and alcohol in order, because exhaustion and hangovers make OCD louder. Guided self-help books based on CBT help with mild OCD alongside treatment.
Is OCD different in pregnancy or after birth?
Yes. OCD often starts or worsens in pregnancy and the months after birth, typically with intrusive thoughts of harm coming to the baby; these thoughts are symptoms, not intentions, and they are common and treatable. Treatment is ERP first, with any medication chosen with pregnancy or breastfeeding in mind, and the doctor coordinates with your maternity services.
How do I stop OCD coming back after treatment?
Keep using the ERP skills after therapy ends, expect a few intrusive thoughts during stress and treat them as expected noise rather than a relapse, avoid slipping back into reassurance-seeking, and if you take an SSRI for OCD, stop it only gradually and with your doctor. Booster therapy sessions at the first sign of rituals creeping back usually prevent a full return.
