Norvasc belongs to a group of medical preparations called calcium channel blockers. It is used to dilate blood vessels and slow the heart rate, which reduces blood pressure. It is also particularly helpful in cases of chest pains that are caused by clogged arteries resulting in lack of oxygen in the heart muscle. Remember that such pains often tend to get worse when you have just started on Norvasc or when the dosage is increased. If the pains become too strong to handle, tell your doctor as soon as possible.
Norvasc has a number of side effects that include headache, drowsiness, dizziness, vertigo, nausea, loss of appetite, diarrhea, stomach pains, dry mouth, skin itching, and in some cases certain psychotic symptoms such as insomnia, strange dreams, depression, nervousness. Do not worry, it is rare when all the effects occur at once. Note that in some cases more serious side effects are possible: hands, ankles, or feet swelling, pounding heartbeats, jaundice, severe weakness, or passing out. If you develop any of these, contact your doctor immediately.
You must not use Norvasc if you are allergic to its active agent or any drugs belonging to the same group. The allergic reaction involves hives, significant swelling in your mouth and difficulty breathing. If you have any signes of an allergic reaction, seek emergency medical help.
