Prothiaden (25 mg) can cause side effects such as drowsiness, disorientation, low blood pressure, tingling, nausea, sweating, or involuntary shaking. These effects can affect your ability to drive or operate machinery safely. It is recommended to see how you respond to the medication first, and avoid driving until you are sure it does not impair your alertness or coordination.

Prothiaden (Dosulepin) is a tricyclic antidepressant mainly used for depression and certain types of nerve pain. While it is not a standard treatment for fibromyalgia, doctors may sometimes prescribe it off-label to help with pain or sleep issues. It can be helpful when used under medical guidance, but do not take it on your own unless your doctor specifically prescribes it for your condition.

Yes, Prothiaden (dosulepin) may interact with other drugs such as domperidone (reduced metabolism and efficacy), monoamine oxidase inhibitors (risk of serious or potentially fatal reactions), alcohol and other CNS depressants (increased sedation), SSRIs (raised dosulepin levels), anticholinergic agents (enhanced anticholinergic side effects), and sympathomimetic drugs such as adrenaline or noradrenaline (potentiated cardiovascular effects). This list is not exhaustive, and Prothiaden (dosulepin) may interact with other medicines as well, so inform your doctor about all medications you are taking, including over-the-counter and herbal products, to avoid potential interactions.
