Why is it important to keep my appointments with the doctor?
Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
- Pregnancy tests must be done before and during treatment to know if this medicine is suited for you to use.
- Routine tests (e.g. complete blood count) may be done while you are being treated with this medicine. Your doctor will advise you about how often you need to have these tests.
- Regular monitoring of your eyesight may also be needed. Your doctor may advise you to use a certain type of eye drops called preservative-free artificial tears while you are being treated with this medicine.
- Regular monitoring of signs of bleeding and administration reactions may also be needed.
You may experience some problems with your eyesight, such as blurred vision while being treated with Belantamab mafodotin. Always keep your doctor updated of any changes in your eyesight. If you cannot see clearly, avoid driving and any activity in which you need to be alert.
Other side effects include any of the following: nausea, vomiting, diarrhoea, fatigue, and fever.
Some side effects may need immediate medical help. Alert your doctor quickly if you experience any of the following:
- rashes, breathlessness, swelling of the face, eyes or mouth
- very bad headache
This medicine will cause the level of your red blood cells, white blood cells and platelets to drop.
Red blood cells carry oxygen around your body. A fall in the level of red blood cells may make you feel tired and worn out.
White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.
Platelets help your blood to clot when there is a cut in the skin. A fall in the level of your platelets may put you at risk of bleeding more than usual. Do not take part in activities where you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises, especially if the bruises appeared on their own) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).
Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Always notify your doctor and pharmacist if you are taking or using any other medicines, including herbal tonics such as traditional Chinese medicines, supplements, and medicines that you buy without a prescription.
Avoid alcohol.
Store in the refrigerator, between 2-8°C. Do not allow to freeze. If frozen, this medicine will become ineffective and should not be used.
Medicines must not be used past the expiry date.
As this is a cancer medicine, always return any unused or expired vials to the clinic, hospital, or pharmacy for disposal. Do not throw it away in the household waste.
