We all know that some diseases can be treated at the pharmacy. But there are some rare, special diseases that are treated in a hospital, under the direct supervision of doctors. Hemin is one such drug, used in very special cases, and given intravenously. So today, let's talk briefly about this Hemin vaccine, what it does, who it is given to, and the things you need to know about it.
What kind of medicine is Hemin?
This medicine called Hemin is used to treat a rare condition called `Acute Intermittent Porphyria.` This is a bit of a complicated name, so let's explain it simply.
This is a genetic condition. To be precise, it is caused by a defect in the process of producing a component of our blood called 'Heme'. This 'Heme' is essential for the hemoglobin in our red blood cells. When this process is disrupted, harmful chemicals accumulate in the body, causing various symptoms such as severe stomach pain and nervous system problems.
So, this medicine called Hemin (the brand name of the medicine may be `Panhematin`) controls the deficiency in the production of `Heme` and alleviates the symptoms. In other words, this is a medicine that affects the basic process that causes the disease.
Things to tell your doctor before using this medicine
Because this is a very specific medication, it is very important to inform your doctor about your complete health history before starting treatment. Be sure to tell them about the following in particular:
- Blood clotting problems: If you have any blood clotting problems (for example, bleeding that doesn't stop quickly), tell us about it.
- Allergies: If you have any allergic reactions, not only to this medicine called Hemin, but also to latex, other medicines, foods, and even some dyes, be sure to tell us about it.
- Pregnancy: If you are pregnant or trying to get pregnant, it is essential to inform your doctor.
- If you are a breastfeeding mother: If you are a breastfeeding mother, you should also tell your doctor before starting treatment.
How is the Hemin vaccine given?
This is not a medicine you can take home. It is a medicine that is given as a saline solution into a vein (infusion) by a trained medical professional in a hospital or clinic. The medical staff will constantly monitor your condition while you are receiving this treatment.
Do you give this medicine to children?
This medicine can usually be prescribed to young children over 16 years of age in some special cases. But it is done with great care and for special reasons. Therefore, if you are giving this medicine to your child, it is important to have a good discussion with your pediatrician and understand everything clearly.
What happens if you take too much medicine?
As this medicine is given under the supervision of a doctor, the chances of an 'overdose' occurring are very low. However, if you suspect that you have overdosed, immediately contact the National Poisons Information Centre at the Colombo National Hospital or the hospital's Emergency Treatment Unit (ETU).
This medicine has been prescribed for you only. Do not share it with anyone else for any reason.
Can there be problems with other medications? (Interactions)
Yes, this can cause problems with some medications. This is especially important if you are taking medications that prevent blood clotting, such as warfarin.
This list is not exhaustive. Therefore, be sure to tell your doctor about all the medications you are taking (including prescription and over-the-counter medications, vitamins, herbal remedies, and supplements), as well as whether you smoke, drink alcohol, or use other drugs. Only then can you be treated safely.
Side effects that may occur during treatment
Like any medicine, the Hemin vaccine can cause some side effects. Some of these require immediate attention, while others are usually not serious. Let's look at these in a table.
