Zanidip is a medicine that belongs to a group called Calcium Channel Blockers (dihydropyridine derivatives), used to treat high blood pressure.
When treating high blood pressure, Zanidip works by slowing the movement of calcium into the cells of the heart and blood vessel walls, which makes it easier for the heart to pump while also widening blood vessels.
High blood pressure (also known as hypertension) can be linked to a number of factors, such as a family history, a diet high in salt or being overweight or inactive.
In addition to some lifestyle changes (such as smoking and/or drinking less and exercising more), it’s often advised to take medication, such as Zanidip, to manage the condition in order to prevent more serious ailments such as stroke, heart attack or blood clots.
Zanidip is a prescription-only medication. Always follow the advice of your doctor and read the patient information leaflet provided in the medication packet.
Take the tablets by swallowing whole with a drink of water, before or after food (but not after a meal that’s high in fat). You should take it at the same time of day, and you should not take Zanidip with grapefruit juice.
Zanidip contains the active ingredient lercanidipine hydrochloride, in strengths of either 10mg or 20mg per tablet.
The normal dose is one 10mg tablet a day, however your doctor may decide to increase this to 20mg if they feel you need it. If you have kidney or liver problems, you should consult your doctor so they can let you know of the appropriate dose.
If you forget to take your Zanidip tablet then you should skip the forgotten dose and move straight onto the next one. Don’t worry but don’t double up on your dose to make up for a missed one.
If you take more Zanidip than you should, then go to your nearest emergency department immediately. An overdose can have symptoms such as extreme dizziness, problems with breathing or feeling weak so lying down with your arms and legs up is advised.
