Why see a psychiatrist?

Deciding to address mental health difficulties is a brave and important step, and for some, medication will play a key role in this journey. If you’re currently taking medication, have in the past, or are considering it as an option, scheduling a consultation with one of our experienced psychiatrists can be a valuable starting point.


Our psychiatrists are not just skilled, but also both expert in many specialist areas. They are knowledgeable about a variety of medications that can aid individuals dealing with a range of different mental health issues, from anxiety, panic attacks and depression to more complex conditions like bipolar disorder, obsessive compulsive disorder (OCD), post traumatic stress disorder (PTSD),  ADHD, personality disorders, among others.


After an initial and thorough assessment, if medication is part of your tailored plan, it can be provided drectly by our team or, if it suits you better, arranged through your GP to ensure ease and comfort. Every aspect of our process is centred around your convenience and wellbeing.

What does a psychiatrist do?

Psychiatrists play a pivotal role in mental health care, blending medical knowledge with a deep understanding of the mind. 


With a background in medical science, psychiatrists understand the intricate relationship between the body and mind. They undergo additional training specifically in mental health, enabling them to diagnose, treat and support those experiencing complex mental health issues.


What makes psychiatrists stand out is their ability to prescribe medication, thanks to their medical background. This capability allows them to offer a rounded approach to treatment, which may include both medication and other therapies tailored to each individual’s needs.


At The Chelsea Psychology Clinic, our psychiatrists are not only highly qualified clinicians but also compassionate and approachable. They are dedicated to creating a space where you feel heard, understood and supported. Each treatment plan is as unique as the person receiving it, ensuring that every client experiences a treatment journey that respects their own personal story, pace and needs.

First psychiatrist appointment - what to expect

In your initial consultation, your psychiatrist will aim to get an understanding of your past experiences, difficulties and the unique journey that has brought you here.


Following your assessment, the psychiatrist will formulate a bespoke treatment plan tailored to address your individual needs. It may involve a balanced combination of medication, administered under the care of your psychiatrist, and therapy, facilitated by your psychologist, ensuring a holistic and evidence-based approach to your treatment plan.


With your consent, the psychiatrist will also liaise with your GP to ensure that your mental health treatment is aligned with any ongoing physical health care. This ensures that every aspect of your wellbeing is supported.

Follow up psychiatrist sessions

Starting medication can be a significant first step, and we understand the importance of personalised care during this phase.


After beginning your medication, scheduling a follow-up session is essential. This allows your psychiatrist to understand how you’re feeling, and address any side effects you may be experiencing. 


Each individual is unique and will respond differently to different medications. It’s common to undergo a period of monitoring and dose adjustments, as many psychiatric medications take time to reach their full effects. During this phase, your feedback is invaluable so that we can tailor the medication to your specific needs.


If we find that a particular medication isn’t the right fit for you, we may explore alternatives. We’re committed to helping you find the medication – and treatment – that best aligns with your body and mental health goals.


You’re not alone. We’re here to support, listen and guide you, ensuring that your treatment is as effective and comfortable as possible.

Frequently asked questions

Psychiatrists and psychologists have distinct roles. Both are essential, yet they cater to different aspects of mental health care.


The main factor that distinguishes the two is the approach to treatment. If there’s a possibility that you may benefit from medication, having an initial consultation with a psychiatrist is advisable. Psychiatrists are medical doctors who specialise in mental health which means they can prescribe and manage medications tailored to your needs.


In many instances, a holistic approach that combines medication with talking therapy is the most effective. For this reason, you may see both a psychiatrist and a psychologist. Psychologists specialise in exploring the emotional, psychological and behavioural aspects of mental health. Through talking therapy, they can help you unravel any underlying issues that might be holding you back and equip you with healthier coping strategies.

Simply put, choosing between a psychiatrist and a psychologist is less about either/or but more about an integrated approach to mental wellness. We focus on offering a tailored journey that brings together the expertise of both professionals to ensure that your path to better mental wellbeing is both holistic and highly personalised.

A clear indicator of successful psychiatric treatment is reduced or absent symptoms, and enhanced wellbeing, and in some cases, reaching a point where medication may no longer be necessary.


Ultimately, each journey to mental wellness is deeply personal. Our dedicated team of psychiatrists are committed to walking this path with you, adapting and responding to your evolving needs to ensure that your treatment is as effective as possible.

If you have received a diagnosis that doesn’t feel right to you, it is always possible to get a second opinion. Our psychiatrists are not only well-versed in diagnosing but also in formulating personalised medication plans, and they are able to carry out a comprehensive review of your current diagnosis and treatment plan. Our team will offer insights, clarity and modifications if needed.

Yes, absolutely. We recognise that integrating diverse perspectives and expertise can be instrumental in enhancing the quality and effectiveness of treatment. Our psychiatrists are well-equipped to work alongside clinicians from outside the clinic to provide a comprehensive and unified approach to your treatment.

Absolutely. Initiating this process will begin with a comprehensive psychiatrist consultation. In this session, you’ll have the opportunity to discuss your history, current medication, and the reasons behind your desire for change. We believe in a collaborative approach; your insights, experiences and preferences are central to crafting a plan that is both effective and tailored to you. 


Your psychiatrists will explore the different options available and consider the potential impacts of any adjustments to your medication. We are committed to ensuring that any modification to your treatment prioritises your safety, comfort and overall wellbeing.
