Prothiaden, containing the active ingredient dothiepin hydrochloride, is a tricyclic antidepressant (TCA) prescribed for the management of major depressive disorders and associated anxiety symptoms. It functions by restoring the balance of certain natural substances (neurotransmitters) in the brain, such as serotonin and norepinephrine, which are crucial for mood regulation. This medication is known for its dual action, offering both antidepressant and sedative effects, making it particularly useful for patients experiencing sleep disturbances alongside depression. Always use under strict medical supervision to ensure optimal therapeutic outcomes and minimize risks.

Common use
Prothiaden is primarily indicated for the treatment of major depressive episodes. It is also used off-label for anxiety disorders, panic attacks, and as an adjuvant therapy in certain chronic pain syndromes such as neuropathic pain or migraine prophylaxis. Its sedative properties make it suitable for patients with significant insomnia related to depression. It is generally reserved for cases where first-line treatments like SSRIs have been ineffective or poorly tolerated.
Dosage and direction
The initial adult dosage is typically 75mg daily, usually administered as a single dose at bedtime to capitalize on its sedative effect and minimize daytime drowsiness. Depending on patient response and tolerance, this may be gradually increased to a maximum of 150mg per day, though some severe cases under close supervision may use up to 225mg daily. Elderly or debilitated patients often start at a lower dose, such as 25–50mg daily. Dosage adjustments should be made cautiously, at intervals of no less than one week. Tablets should be swallowed whole with water, and not crushed or chewed.
Precautions
Patients should be monitored for worsening depression, suicidal ideation, or unusual changes in behavior, especially at the beginning of treatment or after dosage changes. Use with caution in patients with a history of cardiovascular disease, glaucoma, urinary retention, or seizure disorders. Avoid abrupt discontinuation to prevent withdrawal symptoms. Alcohol consumption should be avoided as it can enhance sedative effects and impair judgment. Regular liver function tests and blood counts may be advised during prolonged therapy.
Contraindications
Prothiaden is contraindicated in patients with known hypersensitivity to dothiepin or other TCAs. It must not be used concurrently with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing them due to risk of serotonin syndrome. Other contraindications include recent myocardial infarction, severe liver impairment, and certain cardiac conduction defects. It is also not recommended during the acute recovery phase after a heart attack.
Possible side effect
Common side effects may include drowsiness, dizziness, dry mouth, blurred vision, constipation, and weight gain. Less frequently, patients may experience orthostatic hypotension, increased heart rate, sweating, or sexual dysfunction. Serious but rare adverse effects include urinary retention, seizures, jaundice, blood dyscrasias, or exacerbation of psychosis. Any persistent or severe side effects should be reported to a healthcare provider immediately.
Drug interaction
Prothiaden can interact with numerous medications. Significant interactions include MAOIs (risk of serotonin syndrome), other CNS depressants like benzodiazepines or opioids (increased sedation), anticholinergic drugs (enhanced side effects), and antihypertensives (potentiated hypotension). It may also interact with SSRIs, SNRIs, tramadol, warfarin, and certain antiarrhythmics. Always inform your doctor of all medications, including over-the-counter drugs and supplements.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next scheduled dose. In that case, skip the missed dose and resume the regular dosing schedule. Do not double the dose to make up for a missed one, as this increases the risk of side effects.
Overdose
Overdose of Prothiaden can be severe and potentially fatal. Symptoms may include extreme drowsiness, agitation, confusion, seizures, hallucinations, irregular heartbeat, respiratory depression, and coma. Immediate medical attention is critical. Treatment is supportive and may include gastric lavage, activated charcoal, and management of symptoms such as arrhythmias or seizures in a hospital setting.
Storage
Store at room temperature (15–30°C), in a tightly closed container, away from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging. Dispose of any unused medication properly according to local guidelines, preferably through a pharmacy take-back program.

Reviews
Clinical studies and patient reports generally indicate that Prothiaden is effective in alleviating depressive and anxiety symptoms, particularly where sedation is beneficial. Many users note improved sleep and reduced nervousness. However, side effects like weight gain and drowsiness are commonly reported. It is often regarded as a valuable option for treatment-resistant cases, though individual responses can vary. Long-term satisfaction typically correlates with appropriate dosing and regular follow-up care.
