Things you need to know about Romosozumab Injection

It's normal for our bones to gradually weaken as we age, isn't it? In medicine, we call this osteoporosis. When bones become weak, the risk of breaking a bone increases significantly, even from a small fall or accident. So, a special injection called Romosozumab is given to treat this condition and help strengthen bones again. Your doctor may have told you about this medicine. Let's learn about it simply and precisely today.

What is this medicine called Romosozumab?

Simply put, Romosozumab is a drug that is used to prevent and treat osteoporosis. In our country, it is available under the brand name EVENITY . The main function of this vaccine is to strengthen your bones and reduce the risk of them breaking easily (fracture).

This is a bit of a complicated, special type of medicine. We call it a ``monoclonal antibody'' in medical terms. That means this medicine is made using parts of our own immune system. So it can only go to a specific target in the body and work. The Romosozumab vaccine directly targets the balance between new bone formation and old bone breakdown. What this medicine does is speed up the formation of new bone while controlling the breakdown of old bone. This is how your bones gradually become stronger.

What should you tell your doctor before taking this medicine?

This is very important. Before starting the Romosozumab vaccine, you should inform your doctor about your complete health history. Because, we need to be very careful when using this medicine with certain medical conditions. See the table below.

Situation you need to report Why is it important? (Simply)
If you have had a heart attack or stroke in the past, or if you have heart disease. This medicine can very rarely increase the risk of heart attack or stroke, so if you already have that risk, it's important to let your doctor know.
Kidney diseaseIf there is, especially if you are on dialysis . When the kidneys are not functioning properly, calcium levels in the body can change. This medication also affects calcium levels, so special care is needed for kidney patients.
If you have been told that your blood calcium level is low . Romosozumab can temporarily lower blood calcium levels. Therefore, you should make sure your calcium levels are normal before starting the medication.
If you have problems with your teeth or gums , are having teeth extracted, or are using a set of artificial teeth (dentures). Osteonecrosis of the jaw can occur very rarely when taking this medication. Therefore, special care should be taken with dental health.
If you are pregnant or trying to get pregnant . There is still not enough information about the safety of this medicine during pregnancy, so it is not recommended at this time.
If you are a mother who is breastfeeding . Since there is no clear information about whether the medication passes to the baby through breast milk, you should talk to your doctor about this.
If you have allergies to Romosozumab or any other medicine or food . Informing your doctor about any allergies can help prevent a severe allergic reaction.

How do you use this medicine?

Romosozumab is not a medicine you can take home and use.

  • This is a subcutaneous injection .
  • This is only given by a doctor or trained nurse in a hospital or clinic .
  • Two injections are usually given once a month (at the same time). The total treatment period is 12 months.

Attention: This medicine is for you only. Do not share it with anyone else for any reason.

What to do if you miss a dose of medication?

It is very important to get the vaccine on time during this treatment. If you are unable to go to the hospital or clinic on the scheduled date, call your doctor immediately and schedule an appointment for the next available date. Do not skip doses.

Use them exactly as directed.
  • Blood tests: Your doctor may order blood tests to check your blood calcium levels and kidney function.
  • Severe pain: Some people taking this medicine may experience severe pain in their bones, joints, or muscles. If you experience severe pain, tell your doctor right away , rather than waiting for it to go away on its own.
  • Jawbone problems: As mentioned earlier, a very rare side effect is osteonecrosis of the jaw. This is when the blood supply to the jawbone is reduced, causing the bone to weaken and die. If you have any symptoms such as severe pain inside your mouth or jaw, swelling, redness, numbness, a wound that is not healing after a tooth extraction, or a pus-like fluid coming out, tell your doctor and dentist immediately.
  • Dental Health: Therefore, be sure to tell your dentist that you are taking this medication. It is best to have a dental checkup and address any problems before starting the medication. Also, brushing and flossing your teeth well is very important during this time.
