Case 1. Acute hepatitis-like syndrome attributed to amlopidine.
A 76 year old man with diabetes and end-stage renal disease developed jaundice while on long term nifedipine therapy (60 mg daily for
3 years) for hypertension. He was taking insulin, but no other medications. He had no risk factors for viral hepatitis and did not drink alcohol. Serum bilirubin was 2.5 mg/dL and rose over the next few months to 6.2 mg/dL. Tests for acute hepatitis A, B and C were negative and abdominal ultrasonography showed a normal liver and gallbladder. Nifedipine was stopped and he recovered rapidly. Several months later, Amlopol was started (10 mg daily) and within 6 weeks, he developed jaundice and a cholestatic pattern of serum enzyme elevations. Once Amlopol was stopped, liver tests improved and were normal three weeks later.
What should I avoid while taking Amlopol?

Q: I have taken Norvasc for more than 10 years. I started taking the generic form with a new pharmacy and have developed a dry persistent cough. Is it possible fillers in the generic form are causing this?
A: Norvasc (Amlopol) belongs to a class of drugs called the calcium channel blockers (CCBs). Calcium channel blockers work by dilating or widening blood vessels to improve blood flow or circulation. Norvasc is used to treat hypertension (high blood pressure) and angina (chest pain), either alone or in combination with other medications. Common side effects of Norvasc include dizziness, drowsiness, tiredness, headache, muscle cramps, weakness, nausea, and stomach pain. According to the prescribing information for Norvasc, coughing is a side effect that is reported rarely (less than one percent of patients) in patients taking this medication. If you were not experiencing cough while taking the brand-name product, it could be something in the generic formulation, or it could be totally unrelated. Consult with your doctor about your cough to make sure it is not a symptom of an underlying medical condition. Your doctor is best able to properly evaluate you and determine whether or not your cough is related to the medication. It may be that you need to try the brand name again to see if the cough goes away. Your doctor can specify the need for the brand name product to your pharmacist. Your pharmacist can advise you on your insurance requirements if the brand name product is necessary for you. Do not stop your current medication without talking to your doctor first. For more specific information, consult with your doctor or local pharmacist for guidance based on your health status and current medications, particularly before taking any action.
