Angiogenesis Inhibitors

Overview

Angiogenesis inhibitors are a group of medicines. They block signals in the body that help new blood vessels grow. New blood vessels can feed a cancer or cause harm in some eye and other diseases. These medicines are usually started and watched by specialist teams, not by a GP alone. Your GP may help coordinate your care.

These are specialist treatments, not everyday GP medicines. They are used for certain cancers and some eye and other conditions, so most people will never need them.

People of all ages can receive them, but they are most often used in adults with cancer or eye disease. Children may receive them for certain rare conditions under specialist care.

Symptoms

Common symptoms

• High blood pressure — often silent, so regular checks matter
• Tiredness
• Loose stools or diarrhea
• Feeling sick or less hungry
• Mouth sores
• Skin rash, dryness, or changes
• Bleeding or bruising more easily
• Nosebleeds
• Protein in the urine found on tests
• Changes in thyroid blood tests
• Slower wound healing

Symptoms in children

• Children receiving these medicines are cared for by specialist teams. Side effects can affect growth, development, and dental health, so regular check-ups are important. Ask your child's team what to watch for.
• Children may feel more tired or have changes in appetite. Report any new or worsening symptoms to the specialist team.

Symptoms in older adults

• Older adults may be more affected by tiredness, dehydration, dizziness, and blood pressure changes.
• Many older adults take other medicines. Keep an up-to-date medicine list and ask for a review.
• Report confusion, falls, or new weakness to your care team.

Causes

Main causes

• This article is about a group of medicines, not a disease with causes.
• They are used when a condition involves abnormal new blood vessel growth.
• They work by blocking signals that help new blood vessels form.

Risk factors

• Having a condition where abnormal blood vessel growth plays a role
• Uncontrolled high blood pressure
• Bleeding or clotting problems
• Recent surgery or planned surgery
• Pregnancy or breastfeeding — ask your specialist
• Taking other medicines that affect bleeding or blood pressure

When to see a doctor

See a doctor urgently if:

• Any severe or sudden symptom listed in the emergency section
• A side effect that is getting worse
• Fever or signs of infection
• Being unable to keep fluids down

Book a routine appointment if:

• Before starting treatment, to review your health and other medicines
• New mild side effects or changes you notice
• Planning surgery, dental work, or a procedure
• Travel plans or questions about vaccines
• Any questions about how the medicine is working

Diagnosis

You are not diagnosed with angiogenesis inhibitors. Your specialist first diagnoses the condition being treated and then decides whether this type of medicine is likely to help. They consider your overall health, other treatments, and possible risks.

Tests that may be done

• Blood pressure checks
• Blood tests for blood counts, kidney, liver, and thyroid function
• Urine tests to check for protein
• Scans to see how the condition is responding
• Eye exams if you are having eye treatment
• Heart checks if needed

What to expect at your appointment

You will usually have a check-up before starting and regular monitoring during treatment. Your specialist team will explain the plan, what side effects to watch for, and when to contact them.

Treatment

Angiogenesis inhibitors are specialist medicines used to slow or shrink disease by reducing new blood vessel growth. They are not a general-practice first-line treatment. Your specialist team decides if they are suitable and monitors you closely.

Self-care at home

• Keep all appointments and monitoring tests
• Track your symptoms and side effects in a diary
• Check your blood pressure at home if your team asks you to
• Ask before taking any new medicine, supplement, or herbal product
• Tell your team before surgery, dental work, or wound care
• Practice good hand hygiene and food safety
• Get rest and ask for help when you need it

Medical treatments

These medicines are given in different ways depending on the condition: as tablets, injections under the skin, into a vein, or into the eye. They may be used alone or with other treatments. Your specialist team will set the schedule and monitor blood pressure, blood tests, urine tests, and other checks. They will also manage side effects and decide if changes are needed.

When is surgery considered?

Tell your care team before any surgery, dental procedure, or wound care. These medicines can affect bleeding and healing. Your specialist may advise a temporary pause or other precautions.

Living with this condition

Plan your days around rest and appointments. Keep a symptom diary and a current medicine list. Avoid people with infections when possible. Ask your specialist nurse about practical help and what to do in an emergency.

Lifestyle tips

• Stay gently active if your team says it is safe
• Eat regular, balanced meals and drink enough fluids
• Avoid smoking and limit alcohol
• Protect your skin from sun and use gentle skin care
• Keep up good mouth care
• Wash your hands often
• Ask before travel or major changes in routine

Diet and exercise

There is no single special diet for everyone. Eat balanced meals and enough fluids unless your team gives other advice. If your immune system is low, follow food safety advice. Gentle exercise, such as short walks, can help with tiredness, but ask your team about safe limits.

Mental health and emotional wellbeing

Living with a serious illness and treatment can cause worry, low mood, or fear. These feelings are common. Talk to your specialist team or GP. If you feel you may harm yourself or are in crisis, contact your local emergency number or a local crisis service right away.

Prevention

You cannot prevent needing this type of treatment. You can lower the chance of serious problems by keeping monitoring appointments, checking blood pressure as advised, and reporting side effects early.

Vaccines

Ask your specialist team before any vaccine. Some vaccines may not be suitable during treatment, and timing may need to be planned.

Screening programmes

Keep up with recommended screening for your age and risk. Ask your GP what is right for you.

Complications

If left untreated

• The condition being treated may keep growing or cause damage.
• Uncontrolled high blood pressure can strain the heart, brain, and kidneys.
• Bleeding or blood clots can become serious.
• Poor wound healing or infection can worsen.
• Eye inflammation or vision problems may get worse if not checked.

Long-term outlook

For many people, angiogenesis inhibitors can slow or shrink disease and improve symptoms. Not everyone responds, and side effects vary. Regular monitoring lets your team adjust support and act early. Ask your specialist team about your own outlook and what to expect.
