Prothiaden Tablet (Dosulepin) – Treatment of Depression & Anxiety Disorders

Prothiaden Tablet is a tricyclic antidepressant (TCA) containing Dosulepin, primarily prescribed for treatment-resistant depression and anxiety disorders. This potent medication works by balancing brain chemicals (serotonin and norepinephrine) that regulate mood and emotional stability. Particularly effective for patients unresponsive to first-line antidepressants, it also helps manage neuropathic pain, obsessive-compulsive disorder (OCD), and insomnia. For optimal results, take at bedtime due to its sedative effects. While side effects like dry mouth or dizziness may occur initially, they typically subside as your body adjusts. Always complete the full prescribed course, as abrupt discontinuation may cause withdrawal symptoms.

• Treatment-resistant depression
• Generalized anxiety disorder
• Obsessive-compulsive disorder (OCD)
• Neuropathic pain
• Insomnia
• Bed-wetting (nocturnal enuresis)

Benefits of Prothiaden Tablet:

As a tricyclic antidepressant, Dosulepin inhibits reuptake of serotonin and norepinephrine in brain synapses, increasing availability of these mood-regulating neurotransmitters. This dual action helps stabilize emotional responses and reduce anxiety/depression symptoms.

FAQs:

Q1. How long does Prothiaden take to work for depression?

Initial effects may appear in 1-2 weeks, but full therapeutic benefits typically require 4-6 weeks of consistent use.

Q2. Why must Prothiaden be tapered before stopping?

Abrupt discontinuation can cause withdrawal symptoms (aggression, anxiety, insomnia). Always reduce dose gradually over 4 weeks under medical supervision.

Q3. Can Prothiaden cause weight gain?

Yes, some patients experience increased appetite. Manage through diet control and regular exercise.

Q4. Is Prothiaden safe for elderly patients?

Elderly require lower doses due to increased sensitivity to side effects, especially cardiac and cognitive impacts.

Q5. Can Prothiaden be used for nerve pain?

Yes, it’s effective for certain neuropathic pain conditions, though not approved for trigeminal neuralgia or burning mouth syndrome.

Q6. Why is Prothiaden not a first-line antidepressant?

Due to its significant side effect profile and overdose risk, it’s reserved for cases unresponsive to newer antidepressants.

Q7. What precautions are needed when standing up?

Rise slowly to prevent orthostatic hypotension (sudden BP drop causing dizziness).
