A concerning list of side affects with NAMZARIC...
WARNINGS AND PRECAUTIONS
Cardiovascular Conditions
NAMZARIC may have vagotonic effects on the sinoatrial and atrioventricular nodes manifesting as bradycardia or heart block. Bradycardia or heart block may manifest in patients both with and without known underlying cardiac conduction abnormalities. Syncopal episodes have been reported in association with the use of donepezil hydrochloride, an active ingredient in NAMZARIC.
Peptic Ulcer Disease and Gastrointestinal Bleeding
Patients treated with NAMZARIC should be monitored closely for symptoms of active or occult
gastrointestinal bleeding, especially those at increased risk for developing ulcers, those with a history of ulcer disease, or those receiving concurrent nonsteroidal anti-inflammatory drugs (NSAIDs).
Nausea and Vomiting
NAMZARIC can cause diarrhea, nausea, and vomiting. Although in most cases, these effects have been mild and transient, sometimes lasting one to three weeks, and have resolved during continued use of donepezil hydrochloride, patients should be observed closely at the initiation of treatment.
Genitourinary Conditions
NAMZARIC may cause bladder outflow obstructions. Conditions that raise urine pH may decrease the urinary elimination of memantine, an active ingredient in NAMZARIC, resulting in increased plasma levels of memantine.
Seizures
Cholinomimetics, including donepezil hydrochloride, are believed to have some potential to cause generalized convulsions. However, seizure activity also may be a manifestation of Alzheimer's disease.
Pulmonary Conditions
Cholinesterase inhibitors should be prescribed with care to patients with a history of asthma or obstructive pulmonary disease.
ADVERSE REACTIONS
•The most common adverse reactions, occurring at a frequency of at least 5% in patients taking memantine hydrochloride extended-release 28 mg/day, and greater than placebo, were headache (6% vs 5%), diarrhea (5% vs 4%), and dizziness (5% vs 1%).
•The most common adverse reactions, occurring at a frequency of at least 5% in patients taking donepezil, and at twice or more the rate of placebo, were diarrhea (10% vs 4%), anorexia (8% vs 4%), vomiting (8% vs 4%), nausea (6% vs 2%), and ecchymosis (5% vs 2%).
