Norvasc

Drug Uses

Norvasc is a calcium channel blocker that is used in the treatment of hypertension and angina. It widens the dilated blood vessels and makes it easier for the heart to pump thereby lowering its workload and preventing angina pectoris.

How it is taken

Norvasc comes as a tablet that must be taken by mouth with food or a glass of milk to avoid an upset stomach.

Do not eat grapefruit or drink grapefruit juice for at least one to two hours before and after taking Norvasc. Do not stop without consulting your doctor. Your doctor might prescribe a low salt or low sodium diet while you are taking Norvasc.

The best way to use the drug is as recommended by your doctor.

Missed Dosage

If you miss a dose of Norvasc then you may take it as soon as you remember and adjust the remaining doses accordingly. However, if it is nearly time for the next dose then you may skip this dose and continue with the regular dosage. Do not take a double dose to make up for the missed dose.

Overdose

A Norvasc overdose may require immediate medical attention as it causes symptoms like dizziness, weakness, chest pain, shortness of breath, fainting, unusually fast or slow heartbeat, coma, slurred speech, and confusion.
