Drug Warnings: Before taking Vyconil-SR 75, tell your doctor if you have glaucoma (especially narrow-angle), urinary retention or prostate enlargement, heart disease or previous heart attack, arrhythmias or a family history of long QT, seizure disorders, bipolar disorder, thyroid disease, or significant liver disease. Use caution with driving or machinery until you know how you react, and limit alcohol because it can increase drowsiness and impair judgment.
Drug–drug interactions: Do not use clomipramine with MAO inhibitors or within 14 days of stopping one. Combining Vyconil-SR 75 with other serotonergic medicines (SSRIs/SNRIs, linezolid or methylene blue, tramadol, lithium, triptans, or St John’s wort) increases the risk of serotonin syndrome and requires close medical supervision. Medicines that affect heart rhythm or lower the seizure threshold need caution. Strong CYP2D6 or CYP1A2 inhibitors or inducers (for example fluoxetine, paroxetine, bupropion, quinidine, ciprofloxacin, carbamazepine) can change clomipramine levels; your clinician may adjust therapy. Adding other anticholinergics may worsen dry mouth and constipation; with antihypertensives it may enhance postural dizziness.
Drug–food interactions: Vyconil-SR 75 can be taken with or without food; a light meal may reduce stomach upset. Take it about the same time each day. Alcohol should be limited.
Drug–disease interactions: Extra care is needed in people with cardiac conduction abnormalities or long-QT risk, 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 monitor treatment safely and choose the most suitable regimen.
