Adults:
Patients who have not previously been prescribed a Nifedipine product should start with one tablet once daily. For hypertension and the prevention of angina, the recommended dose is 20 mg twice daily, taken during or after a meal. The dose may be adjusted within a range of 10 mg twice daily to 40 mg twice daily. Patients with impaired liver function should begin treatment at 10 mg twice daily under careful monitoring. No dose adjustment is needed for patients with impaired kidney function.
Side Effects
Reported side effects include headache, flushing, lethargy, gravitational oedema, rash, nausea, increased frequency of urination, eye pain, gum hyperplasia, depression, tremor, photosensitivity and, in a few cases, jaundice. These reactions may subside once treatment is stopped. In some patients with angina pectoris, starting Nifedipine may trigger attacks of ischaemic pain.

Because kidney disease can alter absorption of the drug, exercise caution when treating patients with renal impairment.
