Drug Warnings: Before starting Vyconil-25 or Vyconil-50, tell your doctor if you have glaucoma (especially narrow-angle), urinary retention or prostate enlargement, heart disease or a history of heart attack, arrhythmias, seizure disorders, bipolar disorder, thyroid disease, significant liver disease, or a history of low sodium. Use caution with activities requiring alertness until you know how the medicine affects you, and limit alcohol because it can increase drowsiness and impair judgment.
Drug–drug interactions: Do not combine clomipramine with MAO inhibitors; allow a 14-day washout when switching either way. Using it with other serotonergic medicines (SSRIs/SNRIs, linezolid or methylene blue, tramadol, lithium, St John’s wort) raises the risk of serotonin syndrome and needs close supervision. Caution is required with drugs that prolong the QT interval or lower the seizure threshold. Strong inhibitors or inducers of CYP2D6 or CYP1A2 (for example fluoxetine, paroxetine, bupropion, quinidine, ciprofloxacin, carbamazepine) can alter clomipramine levels; your clinician may adjust therapy. Combining with other anticholinergics increases dry mouth and constipation; with antihypertensives it may enhance postural dizziness.
Drug–food interactions: The tablets can be taken with or without food; a light meal may reduce stomach upset. Alcohol should be limited.
Drug–disease interactions: Extra care is needed in people with cardiac conduction problems, glaucoma, urinary retention, epilepsy, bipolar disorder, significant hepatic disease and in the elderly. Share your full medical history and medication list so your clinician can choose the most suitable strength and monitor treatment safely.
