No, it is not safe to take amlodipine together with Nicardia Retard (which contains nifedipine). Both medicines belong to the same class of drugs called calcium channel blockers. Taking them together can lead to an double-dosing effect, causing your blood pressure to drop too low and significantly increasing your risk of side effects like severe dizziness, headaches, rapid heart rate, and ankle swelling. Your current blood pressure of 130/84 mmHg shows that your existing treatment is working well. Please do not add amlodipine or modify your prescribed regimen without consulting your cardiologist or physician first.
