Bleeding that will not stop when platelets are low | CION Cancer Clinics
If bleeding will not stop and the platelet count is low, call 108 or go to the nearest emergency department now. Press firmly on the bleeding on the way and take the latest blood report. Low platelets mean blood cannot plug a cut properly, so even a nosebleed can become serious. This page explains what to do, which signs cannot wait, and what it cannot tell you. At CION Cancer Clinics, our haematology team supports patients and families through treatment, cost questions and life at home.

If the bleeding has not stopped, act now
Call 108 or go to the nearest emergency department straight away. Tell the staff at the door that the person has a blood cancer or a blood disorder and a low platelet count. Keep firm pressure on the bleeding on the way. Go at once, without waiting for the morning, for a call back from the clinic, or to see if it settles. Take the latest blood report and the treatment summary with you.
The short answer
Why will the bleeding not stop when platelets are low?
Platelets are the small blood cells that plug a cut. When there are too few of them, a small cut, a nosebleed or bleeding gums can keep going far longer than normal, and that needs hospital care the same day.
What causes the low count
In blood cancers the count often drops because the disease crowds out normal cells in the bone marrow, the spongy tissue inside bones where blood is made. Chemotherapy lowers it too, usually for a stretch of days after each cycle. Some infections and some medicines push it lower still. Your report may call this a low platelet count or use a longer medical word for the same thing.
Why it cannot wait
A bleed you can see is only part of the worry. The same low count that lets a nosebleed run on can let bleeding happen inside the body, where you cannot see or press on it. The emergency team will check the count, look for hidden bleeding and decide whether a platelet transfusion is needed. They can only do that once you arrive.
This page is for families at home. It is not a substitute for the emergency department, and it cannot tell you how serious a particular bleed is.Not sure whether this applies to you?
Ask an oncologistOn the way
What should you do while getting to hospital?
-
Call for help first
Call 108, or ask someone else to arrange transport while you deal with the bleeding. If you are alone, call before you do anything else.
-
Press firmly and keep pressing
Use a clean cloth or gauze and press hard on the bleeding point. Do not lift it every minute to check. If blood soaks through, add another cloth on top rather than pulling the first one away.
-
For a nosebleed, sit up and lean forward
Pinch the soft part of the nose, just below the bone, and breathe through the mouth. Do not tip the head back. That sends blood down the throat, where it can cause vomiting.
-
For bleeding gums, use cold and gauze
Bite gently on a folded piece of gauze. Sipping ice-cold water can help. Do not brush, rinse hard or poke at the area.
-
Gather what the hospital needs
The latest blood report, the discharge or treatment summary, the list of every medicine being taken, and your haematologist's phone number. Tell the emergency doctor if a blood thinner is among them. Do not stop or skip any medicine on your own.
Know the signs
Which kinds of bleeding need hospital care today?
With a low platelet count, all of these are reasons to go the same day. Some you can see. Some you can only notice.
Bleeding you can see
Pressure is not holding it back, or it starts again as soon as you let go.
Common examples
- A nosebleed that keeps running
- Gums bleeding without stopping
- A cut, a line site or a needle mark still oozing
Blood where it should not be
These can mean bleeding inside the body, even when the person feels fairly well.
Look for
- Vomit that is red or looks like coffee grounds
- Black, sticky stools, or blood in the stool
- Pink, red or brown urine
- Coughing up blood
Signs in the head
Bleeding inside the head is rare but serious. Call 108 at once for any of these.
- A sudden, severe headache
- Confusion, drowsiness or a fit
- Blurred or double vision, or weakness on one side
Changes on the skin
Many tiny red or purple dots, or large new bruises that appeared without a knock, show the count may be falling fast. Heavy periods soaking through pads much faster than usual count too.

Commonly believed
What do families get wrong about bleeding and low platelets?
"It is only a nosebleed. It will stop on its own."
With a normal count, most nosebleeds do. With a low count, a nosebleed that keeps going can lose more blood than it looks like, because much of it runs down the throat. If firm pressure has not stopped it, that is the reason to go.
"Papaya leaf juice or goat milk will raise the platelets fast."
None of these has been shown to stop active bleeding in someone with a blood cancer. Time spent preparing a home remedy is time the emergency team could have used. Ask your haematologist before giving any herbal product, because some affect how the blood clots.
"A platelet transfusion fixes it for good."
A transfusion raises the count for a short while. It does not treat the reason the count is low. Some people need it repeatedly, and in some the transfused platelets do not last as long as expected. Your team will explain what is happening in your case.
"Painkillers from the chemist are harmless."
Some common painkillers make bleeding more likely by stopping platelets from working properly. Before taking any painkiller for a headache or fever, check with your treating team which one is safe for you.
On your report
What do the words on the blood report mean?
- Platelet count (PLT)
- How many platelets are in a small amount of blood. Normal ranges differ between laboratories, so read it against the range printed on your own report.
- Low platelet count
- Fewer platelets than the normal range. How low is dangerous depends on the person, the illness and whether there is bleeding or fever.
- Petechiae
- Pin-point red or purple dots on the skin that do not fade when pressed. They are tiny bleeds under the skin.
- Platelet transfusion
- Platelets from a donor given through a drip to raise the count for a short time.
- Haemoglobin (Hb)
- The part of red cells that carries oxygen. It can fall after a heavy bleed and is checked alongside the platelets.
Being straight with you
What happens at the hospital, and what can this page not tell you?
At the emergency department, the team will stop the bleeding, check the blood counts and look for bleeding you cannot see. Depending on what they find, they may give a platelet transfusion, a red cell transfusion or medicines that help blood clot. The decision rests on the whole picture, not only on one number.
Why a single number does not settle it
Two people with the same platelet count can bleed very differently. Fever, infection, some medicines and problems with clotting factors all change the risk. That is why this page does not give you a number below which to worry. A count read alone, without symptoms and repeat tests, can mislead in either direction.
After the bleed is controlled
Ask the team what caused it, whether the treatment plan needs to change, and what to watch for at home. Ask how your haematologist will be told. At CION, the haematology team reviews the event, discusses the case at a tumour board where needed and coordinates follow-up with the centre that treated the emergency. Bring any transfusion record back to your next appointment.
If you have questions after the emergency is over, call the helpline. Someone will help you work out the next step.Questions we are asked
Common questions about bleeding with low platelets
How long should I press before going to hospital?
With a low platelet count, do not wait to see whether pressure works before calling for help. Call 108 or set off for the emergency department first, and keep pressing firmly on the way. If the bleeding does stop, still tell your haematology team the same day, because it may start again.
The bleeding stopped. Do we still need to go?
Call your treating team the same day and tell them what happened. They may want a blood count checked, because a bleed that was hard to stop suggests the count has fallen. Go to the emergency department at once if it starts again, or if there is headache, black stools, fever or dizziness.
Which hospital should we go to?
The nearest emergency department that is open, even if it is not where treatment is being given. Getting help quickly matters more than going to a familiar place. Carry the treatment summary so the doctors there understand the illness, and ask them to contact your haematologist.
Can I give paracetamol or a painkiller for the headache?
Do not give a new painkiller on your own. A severe or sudden headache with a low platelet count needs checking in hospital, not treating at home. Some painkillers also affect how platelets work. Your treating team will tell you which ones are safe for you.
Will they need to arrange platelet donors?
Sometimes. Many hospitals ask families to help replace the platelets or blood that was used, and some ask for donors in advance. Ask the blood bank what they need and by when. Do not delay going to hospital while you look for donors.
Is bleeding from a central line an emergency?
A small spot of blood on the dressing is common. Bleeding that keeps coming through the dressing, or soaks it, is not. Press firmly with clean gauze beside the line, avoid pulling on it, and go to the emergency department. Tell them the person has a central line and a low count.
How can we lower the chance of bleeding at home?
Use a soft toothbrush, an electric razor and gentle nose blowing. Avoid constipation and straining, contact sports and anything that risks a fall. Ask your team before any dental work, injection or massage. These steps reduce risk but do not remove it.
Does this mean the cancer is getting worse?
Not necessarily. Platelets often fall because of treatment rather than the illness itself, and counts usually recover between cycles. This page cannot tell you what a bleed means for your own outlook. Your haematologist can, once they have seen the counts and the full picture.
