Celexa(A complete guide)

In this blog, we will discuss celexa, its benefits, risks, withdrawal symptoms, intake guidance, recommended dosage and frequently asked questions about celexa.

What is celexa?

celexa is also known as citalopram (in the USA) or Cipramil (In the UK) is an antidepressant drug commonly used to treat anxiety, depression and panic disorders in adults.

Celexa is a mixture of two stereoisomers: R-celexa and S-celexa (unlike Escelexa which is only one enantiomer, s-celexa).

It is most commonly used to treat depression and has fewer side effects than older antidepressants.

It may improve your energy levels and your feeling of being well. 

Celexa has been available in the UK since 1995.

Celexa is available in tablet form but more commonly found as oil liquid drops and medicine in the USA.

You can put the oil drops into water when you want to consume it.

Celexa is licensed for use in the UK and EU for panic disorder with or without agoraphobia.

In the UK, a typical dose costs less than 20 GBP per month.

Celexa has been shown to be 85% effective in treating those with generalized anxiety disorder even when other antidepressants and SSRI’s have been unsuccessful.

In the United States, celexa carries a boxed warning stating it may increase suicidal thinking and behaviour in those under age 24 but these warnings are not present on the UK packaging.

Celexa can also and has also been used to treat:


Body dysmorphic disorder

Obsessive-compulsive disorder.


Premenstrual dysphoric disorder

You can read a brief guide the NHS has for celexa here.

Anxiety, depression and panic disorders are mental wellness problems that can affect anyone of us. In fact, 1 in 4 of us experiences mental wellness problems at some point or the other in our life.

Anxiety, depression or panic disorders could be caused by life events which occur such as bereavement, loss of a friend, an illness, loss of a job or other life events such as war, active combat experience etc

When we experience these traumatic events the brain cells in our brain called neurons release a number of chemicals which in turn go on to stimulate other neurons in our brain.

This neurons then lead to electrical impulses which result in many other parts of the brains being affected.

As you can see mental wellness issues such as anxiety, depression and panic disorders to have some scientific background and they aren’t simply emotional issues which can often be treated by “getting over things”.

One of the chemicals released in our brain is called Serotonin. Serotonin plays a major role here as you will see.

Once Serotonin is released it stimulates other neurons in the brain, it is then taken back up into the neuron cells and repeats the process again.

This will essentially leave you going through a trauma of emotions which result in anxiety, depression and panic disorders.

Celexa(A complete guide)

How does celexa work?

Celexa works by increasing the levels of a mood-enhancing chemical called serotonin in your brain.

Celexa is one of a number of selective serotonin reuptake inhibitor.

This means it increases the amount of circulating serotonin in your brain rather than allowing them to be taken up back into the neurons and release more chemicals which then repeat the process.

Celexa helps reduce the symptoms of depression, anxiety and panic disorders in some people but not everyone.

Should you take celexa?

Celexa isn’t for everyone. Celexa won’t work for everyone and hence certain people with certain medical conditions.

In either case, the use of celexa should be carefully managed.

Celexa should be prescribed to you by your doctor and you should always declare it as one of the medications you take to ensure any other future medication you are prescribed takes it into account.

You should not take celexa if

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you have recently taken any other antidepressants as some older antidepressants can still react with celexa even though you haven’t taken them for a few weeks. You should inform your doctor of any antidepressants you have used. Some antidepressants can interact with celexa and cause your blood pressure to rise very high.
  • If you are under 12 except if prescribed by your doctor
  • If you are going through any treatment involving electroconvulsive therapy (ECT).
  • If you have ever been allergic to any medicine.
  • If you have taken an antidepressant known as a monoamine-oxidase inhibitor (MAOI) within the last two weeks.
  • If you have high blood sugar levels (diabetes mellitus).
  • If you have increased presure in your eye(s) (also known as glaucoma).
  • If you have ever had a bleeding disorder.
  • If you have ever had abnormally ‘high’ moods, called mania.
  • If you are currently taking any other medicines which you have been prescribed for or medicines which you have bought over the counter including any supplements, complementary medicine or herbal treatments. 
  • If you have any liver or kidney disorders.
  • If you have a heart condition or have been told you have an irregular heartbeat. This is because celexa can speed up or change your heartbeat
  • If you have epilepsy.

Guidance on taking celexa:

“Try to take celexa at the same time each day.

It may take up to four weeks after starting this treatment before you feel the full benefit. Do not stop taking it, feeling it is not helping.

Tell your doctor if you feel that you are not getting any better, or if you experience any troublesome side-effects.”]

Before you take celexa you should make sure you have read the above statement but more also as important you should follow the guidelines below.

  • Before taking celexa or any medicine you should always read the manufacturers label in full. This may contain warnings, guidelines on dosage or ingredients which you may be allergic to. It will also provide you with a list of possible side effects so you are aware of any potential side effects of celexa before they occur.
  • You can take celexa before or after food. You can also take it with or without food.
  • celexa can be taken by children or adults over the age of 12

You should never take two doses of celexa at the same time for any reason including trying to make up for a missed dosage.
  •  You are taking celexa in its oral form then your doctor will inform you of how many drops you should take per dosage. You should drop the dosage into a glass of clear water or orange juice so you can count the drops with ease. You should then stir before drinking.
  • If you have trouble sleeping then it is best to take celexa in the morning
  • You should always take celexa exactly as the doctor has asked you to take it. It is usually prescribed once a day and you will usually have flexibility on what time of the day you take it but you must try and ensure you take your doses at the same time every day to avoid ever taking two doses within close proximity of each other. If you find that you have taken two dosages then you should go to the a&E immediately with the packet of the celexa. You may begin to experience the following after you have taken more than 1 dosage within a short period of time: being sick (vomiting), shaking, feeling sleepy, fast heart rate and seizures.

  • Your doctor may prescribe a low dosage of celexa for you if you are currently being treated for a panic disorder. This is because some people may develop anxiety during the first two weeks and your doctor will want to monitor how you are reacting before slowly increasing the amount of celexa you are taking.
  • You should ensure you don’t miss any appointments with your doctor as it is very key they check how you are doing after prescribing you celexa. This could be because they want to reduce or increase the strength of your dosage.

  • You should not buy any over the counter medicine or supplements to consume with celexa without informing your doctor. You should also not get any new prescriptions from any other doctor without informing them that you are currently on a celexa treatment and informing the doctor who prescribed your celexa.

These are very rare but if you find yourself with any allergic reactions you should report this to your doctor immediately. The reactions could include but are not limited to itching., difficulty with your breathing and swelling on the face.

  • If your medicine is out of date then you shouldn’t keep it. Take it to your local pharmacy for disposal or discard it yourself.
