Citalopram Side Effects Explained

Citalopram, a widely prescribed selective serotonin reuptake inhibitor (SSRI), is a cornerstone in the treatment of depression and anxiety disorders. While highly effective for many, like all medications, it can present a range of side effects. Understanding these potential reactions is crucial for patients to manage their treatment effectively and to know when to consult with a healthcare professional. This article delves into the common and less common side effects of citalopram, offering practical advice on how to cope with them and outlining the signs that warrant immediate medical attention.

Understanding Citalopram and Its Effects

Citalopram works by increasing the levels of serotonin in the brain, a neurotransmitter that plays a key role in regulating mood. By balancing serotonin levels, it helps to alleviate symptoms of depression and anxiety. However, this alteration in brain chemistry can also lead to various physical and psychological changes, which are experienced differently by each individual.

Common Side Effects and Coping Strategies

The majority of citalopram side effects are mild and tend to diminish as your body adjusts to the medication, typically within the first few weeks of treatment. Here are some of the most frequently reported common side effects and practical ways to manage them:

Dry Mouth

A dry mouth is a very common side effect. To combat this, try chewing sugar-free gum, sucking on sugar-free sweets, or keeping a water bottle handy to sip throughout the day. Maintaining good oral hygiene is also important.

Increased Sweating

Some individuals may experience excessive sweating. Wearing loose, breathable clothing and using a strong antiperspirant can help. Staying cool, perhaps with the aid of a fan, might also provide some relief. If these measures are insufficient, your doctor might suggest a different antidepressant.

Sleep Disturbances (Insomnia or Drowsiness)

Citalopram can affect sleep patterns. If you find it difficult to sleep, taking your medication first thing in the morning might be beneficial. Conversely, if you experience drowsiness or fatigue, taking the medication in the evening could be a better option. It's advisable to limit alcohol intake, as it can exacerbate drowsiness.

Fatigue and Weakness

Feeling tired or weak is another common side effect. It's essential to avoid activities that require alertness, such as driving or operating machinery, if you are experiencing these symptoms. Reducing alcohol consumption can also help, as alcohol can worsen feelings of fatigue.

Headaches

Headaches can occur, especially in the initial stages of treatment. Ensuring you get adequate rest, staying hydrated by drinking plenty of fluids, and avoiding excessive alcohol consumption are recommended. Over-the-counter painkillers can offer relief, but if headaches persist or are severe, it's important to consult your doctor.

Nausea

Feeling sick is a common side effect that can often be managed by taking citalopram with or after food. Avoiding rich, spicy, or fatty foods may also help. If nausea continues to be a problem, discuss it with your doctor.

When to Seek Medical Advice

While common side effects are usually manageable, certain reactions require professional medical intervention. It's important to consult a doctor or pharmacist if the advice for coping with side effects doesn't help, or if a side effect is particularly bothersome or persistent.

Serious Side Effects: Recognizing the Warning Signs

Serious side effects from citalopram are rare, affecting fewer than 1 in 1,000 people. However, it is vital to be aware of these potential risks and to seek immediate medical help if they occur.

Changes in Menstrual Periods

If you experience changes in your menstrual cycle, such as heavier bleeding, spotting, or bleeding between periods, you should book an appointment with your doctor.

Unexplained Weight Changes

Gaining or losing weight without trying can be a sign that needs to be discussed with your doctor.

Bleeding and Bruising

Seek immediate medical attention if you notice unusual bruising that appears without a clear cause or that increases in size. Bleeding from the gums is also a cause for concern.

Mood and Behavioural Changes

While citalopram is used to treat mood disorders, in rare cases, it can cause significant changes. If you experience intense feelings of happiness, excitement, or restlessness to the point where you cannot sit or stand still, contact your doctor.

Blood in Bodily Fluids

Coughing up blood, blood in your urine, black or red stools, or blood in vomit are serious signs that could indicate internal bleeding and require urgent medical assessment.

Cardiovascular and Neurological Symptoms

Immediate medical help (call 999 or go to A&E) is necessary if you experience chest pain or pressure, shortness of breath, a seizure (or an increase in seizure frequency), severe dizziness, or fainting.

Priapism

Painful erections that last longer than 2 hours, even in the absence of sexual activity, require immediate medical attention.

Uncontrollable Bleeding

Heavy or prolonged bleeding from cuts or nosebleeds that do not stop within 10 minutes warrants urgent care.

Suicidal Thoughts

If you have thoughts of harming yourself or ending your life, this is a critical emergency. Call 999 or go to A&E immediately.

Hyponatremia (Low Sodium Levels)

Symptoms such as headaches, difficulty concentrating, memory problems, confusion, weakness, seizures, or loss of balance can indicate dangerously low sodium levels. Seek immediate medical help.

Severe Allergic Reactions (Anaphylaxis)

A severe allergic reaction to citalopram is rare but can be life-threatening. Signs of anaphylaxis include:

• Sudden swelling of the lips, mouth, throat, or tongue.
• Rapid or difficult breathing, wheezing, choking, or gasping.
• Tightness in the throat or difficulty swallowing.
• Blue, grey, or pale skin, tongue, or lips (on darker skin tones, this may be more visible on palms or soles).
• Sudden confusion, drowsiness, or dizziness.
• Fainting or unresponsiveness.
• For children, limpness, floppiness, or lack of normal responsiveness, with the head falling to the side, backwards, or forwards, or difficulty lifting the head or focusing.
• A swollen, raised, itchy, blistered, or peeling rash.

If you suspect a severe allergic reaction, call 999 immediately. Do not drive yourself to A&E ask someone else to drive you or call for an ambulance. Bring all your current medications with you.

Sexual Side Effects

While citalopram can improve mood and overall well-being, potentially leading to a better sex life, some individuals may experience sexual side effects. These can include:

• Problems achieving or maintaining an erection.
• Difficulties with ejaculation.
• Painful erections.
• Vaginal bleeding.
• Reduced libido (sex drive).
• Difficulty reaching orgasm.

These side effects often resolve within the first few weeks of treatment. However, in some cases, they can be long-lasting and may persist even after discontinuing the medication. If sexual side effects are a significant concern, it is essential to discuss alternative treatment options with your doctor.

Important Considerations

This information covers common and serious side effects, but it's not exhaustive. For a complete list, always refer to the patient information leaflet provided with your medication.

Frequently Asked Questions

Can citalopram cause ringing in the ears (tinnitus)?

While tinnitus is not listed as a common or serious side effect of citalopram in the provided information, it's possible for any medication to cause unexpected reactions in some individuals. If you experience ringing in your ears while taking citalopram, it's best to discuss this with your doctor to rule out other causes and determine if it might be related to the medication.

Can citalopram make anxiety worse initially?

Yes, it is possible for citalopram to temporarily increase anxiety symptoms, particularly during the first few weeks of treatment. This is often referred to as the 'activation' phase. The information states that taking citalopram for panic attacks can sometimes make anxiety worse initially, but this usually subsides after a few weeks. If the increased anxiety is bothersome, speaking to your doctor about a lower starting dose might help.

How long do citalopram side effects usually last?

Many of the common side effects of citalopram tend to improve gradually as your body gets used to the medication, typically within the first few weeks. However, some side effects, particularly sexual side effects, can be long-lasting for some individuals.

What should I do if I experience a serious side effect?

If you experience any serious side effects, such as chest pain, difficulty breathing, seizures, severe dizziness, thoughts of self-harm, or signs of a severe allergic reaction, you should seek immediate medical attention by calling 999 or going to the nearest A&E department. For other serious side effects like unusual bleeding or significant mood changes, contact your doctor promptly.
