Increased risk of suicidal thinking and behavior in children, adolescents, and young adults with major depressive disorder and other psychiatric disorders.
Serotonin syndrome risk with concomitant serotonergic drugs (e.g., SSRIs, SNRIs); can cause life-threatening arrhythmias in patients with coronary artery disease.
Serotonin syndrome; discontinuation syndrome; hyponatremia; bleeding risk; mania/hypomania; seizures; angle-closure glaucoma; QT prolongation (overdose).
Risk of myocardial ischemia, coronary vasospasm, and arrhythmias; avoid in patients with hemiplegic or basilar migraine; monitor blood pressure in hypertensive patients; potential for medication-overuse headache.
Concurrent use with MAOIs or within 14 days of MAOI use; concurrent use with pimozide or thioridazine; hypersensitivity to fluoxetine.
History of coronary artery disease or stroke; uncontrolled hypertension; hemiplegic or basilar migraine; concurrent use of MAO inhibitors; peripheral vascular disease; severe hepatic impairment.
Avoid high-sodium foods as they can counteract the diuretic effect. Limit licorice intake (glycyrrhizin) which can worsen hypokalemia. Grapefruit juice may increase absorption; avoid large amounts. Maintain adequate fluid intake unless fluid restriction is advised.
Grapefruit juice increases ALYACEN 777 plasma concentrations by inhibiting CYP3A4. Avoid grapefruit products. High-fat meals may delay absorption but do not reduce total exposure.
Falmina is a combined oral contraceptive containing ethinylestradiol and drospirenone. Category X: contraindicated in pregnancy. First trimester: no increased risk of major malformations in exposed fetuses based on epidemiological studies, but use is not recommended due to lack of need. Second and third trimesters: associated with increased risk of fetal harm including congenital anomalies (limb defects, heart defects) and adverse outcomes (low birth weight, preterm birth) from continued exposure. Risk of fetal feminization from progestin component in late pregnancy.
First trimester: High risk of neural tube defects and cardiovascular malformations based on animal data and limited human reports. Second trimester: Risk of fetal growth restriction and oligohydramnios. Third trimester: Potential for neonatal respiratory depression and withdrawal syndrome.
Small amounts of ethinylestradiol and drospirenone are excreted in breast milk; M/P ratio not determined. Use may reduce milk production and composition. Avoid use in breastfeeding women, especially during early postpartum period, due to potential for decreased milk supply and presence in milk. Alternative contraception recommended.
Contraindicated due to high excretion into breast milk (M/P ratio ~3.5). Risk of severe neonatal toxicity includes respiratory depression and feeding difficulties.
Falmina is contraindicated in pregnancy; no dose adjustments are applicable because use should be discontinued immediately upon pregnancy diagnosis. No pharmacokinetic data guide dosing in pregnancy as it is not indicated.
No specific dose adjustment studied. Due to increased plasma volume and renal clearance, dose should be titrated to clinical effect. Consider lower starting doses due to narrow therapeutic index.
FALMINA is a high-ceiling loop diuretic used for edema and hypertension. Monitor serum potassium and magnesium regularly; risk of hypokalemia and hypomagnesemia. Ototoxicity is dose-dependent and more common with rapid IV administration or concurrent use of other ototoxic drugs. Onset of action: oral 30-60 min, IV 5 min. Duration: oral 6-8 hr, IV 2 hr. Avoid in anuria, hepatic coma, severe electrolyte depletion.
ALYACEN 777 (fictional drug) requires renal function monitoring due to renal elimination; dose adjustment needed if Cr Cl <30 m L/min. Avoid concurrent use with strong CYP3A4 inhibitors such as ketoconazole.
Take this medication exactly as prescribed; do not increase dose or frequency without consulting your doctor.,Report any hearing loss, ringing in ears, or dizziness immediately, especially if on high doses or other ototoxic drugs.,Weigh yourself daily and notify your doctor if you gain more than 2-3 pounds in 24 hours or lose weight too quickly.,Avoid sudden position changes to prevent dizziness; rise slowly from sitting or lying down.,Limit alcohol intake as it may worsen dizziness and low blood pressure.,This drug may increase blood sugar; monitor glucose if diabetic.,Do not take with NSAIDs (e.g., ibuprofen, aspirin) unless approved by your doctor as they may reduce effectiveness and increase kidney risk.
Take with a full glass of water.,Do not crush or chew extended-release tablets.,Avoid grapefruit juice while taking this medication.,Report any signs of unusual bleeding or bruising immediately.,Complete full course as prescribed, even if symptoms improve.
