In some patients, especially at the beginning of treatment or when the dose is increased, angina attacks may occur and in rare cases, myocardial infarction develops, which requires drug withdrawal.
From the side of the central nervous system: headache, dizziness, general weakness, fatigue, drowsiness. With prolonged use of the drug in high doses – limb paresthesia, tremor, extrapyramidal (parkinsonian) disorders (ataxia, masky face, shuffling gait, tremor of the hands and fingers, difficulty swallowing), depression.
From the digestive system: dyspepsia (nausea, diarrhea or constipation), dry mouth, flatulence, increased appetite. Rarely – gingival hyperplasia, completely disappearing after drug withdrawal. With prolonged use – impaired liver function (intrahepatic cholestasis, increased activity of hepatic transaminases).

Drug Interaction
When used with Corinth with beta-blockers, diuretics, and other antihypertensive drugs, there is an increase in the antihypertensive effect of Corinth.

Symptoms: in severe cases – loss of consciousness up to coma, arterial hypotension, tachy / bradycardia, hyperglycemia, metabolic acidosis, hypoxia, cardiogenic shock with pulmonary edema.
Treatment: Abundant gastric lavage, if necessary, in combination with small bowel lavage. The use of laxatives should take into account the decrease in intestinal muscle tone up to the bowel atony observed with the use of calcium channel blockers. Since nifedipine is not excreted in hemodialysis, it is impractical to carry it out. Plasmapheresis is recommended.
At development of a bradycardia it is necessary to appoint atropine and / or beta-sympathomimetics, at the threatening life of the patient of a bradycardia it is necessary to implant the driver of a heart rhythm on time.
In case of arterial hypotension, which is a consequence of cardiogenic shock and expansion of arterial vessels, 1-2 g of calcium gluconate is introduced into / into, in / in a drop – dopamine (up to 25 mcg / kg body weight / min), dobutamine – up to 15 mcg / kg body weight / min), epinephrine (adrenaline) or norepinephrine (norepinephrine). The calcium content of the serum is maintained at a normal or slightly elevated level.
The introduction of fluid or blood into the body is carried out with caution under the control of hemodynamic parameters.
