How you have cancer drugs
Find out about the different ways you can have cancer drugs or medicines. There is information about
You have some cancer drugs as tablets or capsules that you swallow. You should only get a prescription for cancer drug tablets or capsules from your cancer specialist. You must take them at the right times, as directed by your doctor, specialist nurse or pharmacist. If you have problems swallowing, some medicines are available as a liquid that you drink.
It is important to keep your tablets or capsules in their original packaging. You need to store them in a safe place, away from children because if children took them they could be very harmful. Store them as directed by your pharmacist – for example, many need to be kept at room temperature, and away from heat and direct sunlight. Some need to be kept in the fridge.
Disposing of medicines
It is important to take any unused tablets or capsules back to the pharmacy so that they can be destroyed safely. Don't flush them down the toilet or throw them away.
If you forget to take it
If you forget to take a tablet, don't take a double dose. Tell your doctor or specialist nurse and carry on with your usual dose schedule.

Drugs given in this way usually work very quickly. An injection into a vein is called an intravenous injection (IV). You have the injection through a small tube (cannula) put into a vein in one of your arms. This can stay in for a few days if needed.
A nurse or doctor attaches a syringe to the cannula to inject the drug. The cannula has a rubber bung on it and they might inject the drug through the rubber bung.
Some cancer drugs are diluted in a bag of fluid and you have them as a drip. Your nurse or doctor attaches the drip bag to the cannula or your central line and the drug drips into your vein over 20 minutes or a few hours. Some drugs are given in this way for a few days and an electronic pump keeps the dose rate constant.
Instead of having an injection every time you have your treatment, your doctor or nurse might inject the drugs through a tube put into a vein in your chest, such as a central line, PICC line or portacath.
Central lines usually go into your body in the centre of your chest. Then they run up under your skin to a large vein by your collarbone. The only bit you can see is the length of line that hangs out of the small entry hole in your chest. This is a picture of a central line in place.
The central line can stay in your vein for many months. So you don't need to have needles into your hand or arm each time you have your cancer drug treatment.
Your doctor and nurse can take blood from the line for tests. They can also use the line to give you fluids or other treatment such as antibiotics if you need them.
The video below shows how a tunnelled central line is put in.
PICC stands for Peripherally Inserted Central Catheter. You have it into a vein in your arm. It can be put in during an outpatient appointment under local anaesthetic.
The line runs up the vein inside your arm and ends in a large vein in your chest. PICC lines can be left in for several months and are used in a similar way to central lines.
A portacath is a particular type of central line. It has a small chamber or reservoir that sits under your skin. You can feel the chamber but unless you are very thin you cannot usually see it.
When you need treatment, your nurse puts a needle into the chamber and gives you injections or attaches a drip. The needle stays in place for as long as you need treatment. Then your nurse removes the needle until your next treatment.
The main advantage of a portacath is that you can't see it on the outside of your body. You don't have to have a tube coming out of your chest as you do with a central line. But some people prefer a central line because they don't like having a needle put through the skin each time they need treatment.
If you prefer, you can have the area over the portacath numbed with a local anaesthetic cream before the nurse puts the needle in.
Some drugs are injected into a muscle (intramuscular injections), usually in your buttocks or upper thigh. You might have stinging or a dull ache for a short time after this type of injection, but they don't usually hurt much.
You usually have injections under the skin (subcutaneous injection) into the stomach, thigh or top of your arm. You might have stinging or a dull ache for a short time after this type of injection but they don't usually hurt much. The skin in the area may go red and itchy for a while.
The video below shows you how to give an injection just under your skin (subcutaneously).

You are most likely to have a syringe driver if you need a constant dose of a particular drug but find swallowing difficult. A syringe driver is a battery operated or clockwork pump.
A pharmacist or nurse puts your drug into a syringe. The pump gives the drug from the syringe through a soft plastic tube to a needle that goes in just under your skin. Your nurse will fix the needle in place with a see through plastic dressing stuck over the top.
The pump can give continuous tiny amounts of a drug. Sometimes you have more than one drug. The nurse who sets up the pump will work out the dose of the drug to put in. They also set the pump so that you get exactly the dose you need each hour.
People who are very ill and might be dying at home often have syringe drivers. Drugs given this way can give very good pain and sickness control. It is a very efficient way of having regular medicines at home. A nurse comes to change the syringe every day or so. Some drugs can't be used in syringe drivers because they irritate the skin or don't completely dissolve in water.
Suppositories are small, smooth and slightly pointed wax objects that contain drugs. The suppository goes into your back passage, where the wax melts and releases the drug.
Drugs are absorbed very quickly through the lining of the back passage and it is a very efficient way of taking them. Unfortunately, for many people the thought of having anything put into their back passage is frightening and embarrassing. But it doesn't hurt and you can do it yourself if you find the idea of someone else doing it off putting.
Your nurse can give you suppositories. Or they can give you a disposable glove and some lubricating gel and they explain to you what you have to do.
You can have some drugs as patches stuck on to the skin. HRT and nicotine patches are probably the best known, but painkillers and anti sickness medicines can be given in this way too.
You stick the patches onto your skin like a plaster. The drug is inside the patch and slowly passes through your skin into your body. The patches last between 1 and 2 days. You throw away the old patch each time you change it. They are waterproof so that you can shower, bathe or go swimming while you are wearing them.
If you find it hard to swallow tablets, you might be able to have your drugs as a tablet that dissolves. You can put some drugs on your tongue and when they dissolve you swallow them. You can have anti sickness medicines in this way.
There are other drugs that you put under your tongue. You just leave the drug there to dissolve. This type of tablet is called sub lingual, which means under the tongue. You can have some painkillers in this way.
It is quite usual to have cancer drug treatment in cycles. A cycle means that you have a single cancer drug or a combination of drugs and then have a rest to allow your body to recover.
You might have some chemotherapy injections over a day or two and then have some time with no treatment. The treatment and rest time make up one treatment cycle. When you get to the end of the cycle, it starts again with the next cycle.
If you're having some cancer drugs as tablets you might take them for a few days or weeks and then have a rest period.
Depending on the drug or combination of drugs, an individual treatment may last from a few hours to a few days. Your treatment cycles might be weekly or might take 2, 3 or 4 weeks, depending on the drugs and your particular treatment plan. Some treatment cycles are quite complicated.
Courses of treatment
A series of cycles of treatment is called a course. A treatment course often takes between 3 to 6 months but it can be more or less than that. During that time, you would probably have between 4 to 8 cycles of treatment.
