Description

What is Dothiepin?

Dosulepin is a prescribed antidepressant that is in the tricyclic antidepressant group. It affects the chemical messengers in the brain, including serotonin and noradrenaline, which are involved in the regulation of mood.

Dosulepin is now much less commonly used by healthcare professionals, as there are safer alternatives. NHS guidance says clinicians should not routinely initiate it in new patients.

**What Dosulepin is Used For**

Dosulepin has been licenced for the treatment of depression, particularly where sedation may be considered useful. But current guidance notes its safety concerns and recommends considering alternatives where appropriate.

Patients already taking dosulepin should not stop taking it suddenly. Instead, they should talk with their doctor about their treatment, as antidepressants usually need to be gradually withdrawn to minimise withdrawal symptoms.

How Does Dosulepin Act?

Dosulepin is a tricyclic antidepressant and acts on neurotransmitters related to mood. This may in turn affect symptoms of depression . But everyone responds to treatment differently.

Dosulepin can also cause drowsiness and other effects that may affect your daily activities. Patients should consult a doctor regarding the use of machinery and driving.

Potential Side Effects

Dosulepin can cause side effects as can other medicines. Typical or known effects include:

• Xerostomia
• Vision blurred
• Constipation
• Difficulty urinating
• Sleepiness
• Sweating –
• Dizziness or postural hypotension
• Changes in appetite or weight loss
• Heart rate changes

It can also affect the heart’s rhythm and conduction. For this reason, patients with heart problems require a certain medical evaluation before using it.

Important Safety Information

Particular caution is needed with dosulepin as it can cause serious cardiovascular toxicity and is highly toxic in overdose. NHS guidance therefore advises against starting routine and reviewing existing treatment where appropriate.

Dosulepin can also interact with other medicines. For example, it should not be used with MAO inhibitors or within 14 days of stopping an MAO inhibitor. Some SSRI combinations can also increase levels of tricyclic antidepressants.

Furthermore, alcohol may enhance the central nervous system depressant effects of tricyclic antidepressants. Tell your doctor or chemist about all the medicines and supplements you take.

Can I stop Dosulepin Cold Turkey?

No. If you are taking dosulepin do not stop treatment without medical advice. If you stop the medication suddenly you may experience withdrawal symptoms, so healthcare professionals usually advise that antidepressants should be weaned off slowly when ending treatment .
