Brand names: Istin
Why is it important for my child to take Amlodipine?
If high blood pressure (hypertension) carries on for a long time, it can lead to damage to various parts of the body, such as the brain, heart and kidneys. Amlodipine helps to lower blood pressure by opening up blood vessels.
What is Amlodipine available as?
Tablets: 5 mg, 10 mg
Liquid Medicine: 5 mg or 10 mg in 5 mL, can be ordered from your pharmacist
When should I give Amlodipine
Amlodipine is usually given once each day. This is usually in the morning.
Give the medicine at about the same time(s) each day so that this becomes part of your child’s daily routine, which will help you to remember.
How much should I give?
Your doctor may suggest that your child has a low dose to start with. They may then increase the dose as your child gets used to the medicine and depending on your child’s blood pressure.
Your doctor will work out the amount of Amlodipine (the dose) that is right for your child. The dose will be shown on the medicine label.
It is important that you follow your doctor’s instructions about how much to give.
How should I give Amlodipine?
- Crushed tablets can also be mixed into 5 -10 mL of water (one or two spoons) in a small glass. Make sure your child takes it straight away. You can use an oral syringe to give the mixture to your child.
- Tablets should be swallowed with a glass of water, squash or juice. Your child should not chew the tablets.
- You can crush the tablet and mix it with a small amount of soft food such as yogurt, honey, or mashed potato. Make sure your child swallows it straight away, without chewing.
- Shake the medicine well. Measure out the right amount using an oral syringe or a medicine spoon. You can get these from your pharmacist. Do not use a kitchen teaspoon as it will not give the right amount.
When should the medicine start working?
Your child’s blood pressure will start to come down after a few days, although you will not see any difference in your child.
Your doctor will check your child’s blood pressure to see how well the medicine is working.
What if my child is sick (vomits)?
- If your child is sick less than 30 minutes after having a dose of Amlodipine, give them the same dose again.
- If your child is sick more than 30 minutes after having a dose of Amlodipine, do not give them another dose. Wait until the next normal dose.
If your child is sick again, seek advice from your family doctor, nurse, pharmacist, or hospital. They will decide what to do based on your child’s condition and the specific medicine involved.
What if I forget to give it?
If you usually give it once a day: Give the missed dose when you remember during the day, as long as this is at least 12 hours before the next dose is due. If you remember after this time, do not give the missed dose. Wait until the next usual dose.
What if I give too much?
It may be dangerous to give too much Amlodipine because it may make your child’s blood pressure too low.
If you think you may have given your child too much Amlodipine, contact your doctor or local NHS services (details at end of leaflet) or take your child to hospital. Have the medicine container or packaging with you, even if it is empty. This will be useful to the doctor.
Are there any possible side effects?
We use medicines to make our children better, but sometimes they have other effects that we don’t want (side effects).
Side effects you must do something about
If your child has an irregular or fast heart beat (fluttery or racing), take your child to hospital or call an ambulance straight away.
If your child is short of breath or is wheezing, or their face, lips or tongue start to swell, or they develop a rash, they may be allergic to Amlodipine. Take your child to hospital or phone for an ambulance straight away.
Other side-effects you need to know about
Your child may get some of the following side-effects when they first start taking amlodipine. These effects are usually mild and should wear off after a few days. If they are still a problem after 2 weeks, or you are worried, contact your doctor but continue to give amlodipine.
They may have hot flushing in the face or a headache.
They may feel physically tired (lethargic) or weak, and they may have difficulty getting to sleep.
Your child may feel dizzy or light-headed when they stand up. Encourage them to sit down for a short time after taking the medicine and to stand up slowly and to sit or lie down if they feel dizzy or light-headed.
Your child may get stomach ache or indigestion and feel sick (nausea).
They may get some swelling of their legs or joints.
There may sometimes be other side effects that are not listed above. If you notice anything unusual and are concerned, contact your doctor. You can report any suspected side effects to a UK safety scheme at www.mhra.gov.uk/yellowcard
Can other medicines be given at the same time as Amlodipine?

- Amlodipine should not be taken with some medicines. Tell your doctor or pharmacist about any other medicines your child is taking before giving Amlodipine.
