Prolia

Doctors need to monitor the response of patients taking Prolia. This is done with a Bone Mineral Density test, usually once every 1 to 3 years.

Prolia can make it a bit harder to fight infections. Patients who develop a fever or think they have an infection are advised to tell their doctor.

Prolia been associated with a very rare problem with the jaw called osteonecrosis. This problem is sometimes seen after dental work. Patients should let their doctor know if they develop sudden pain in the jaw.

Alcohol is known to increase fracture risk by decreasing bone mineral density and promoting osteoperosis.

Patients who are prescribed Prolia should stop drinking alcohol, or at least significantly reduce the amount of alcohol that they drink.

The body features an ongoing process called bone remodeling where bones are constantly broken down (bone resorption) and rebuilt.

Bones are broken down by a type of cell called osteoclasts and are built back up by a type of cell called osteoblasts.

In patients with osteoporosis, too much bone is being broken down too quickly.

Before osteoclasts mature and are able to break down bone, they are called pre-osteoclasts. These pre-osteoclasts have a specific receptor on their cell surface called RANK (Receptor Activator of Nuclear factor Kappa B). When RANK is switched “on” by a protein called RANKL (RANK-Ligand), it causes the pre-osteoclasts to mature into bone-dissolving osteoclasts.

Prolia is a protein called a monoclonal antibody that binds to RANK-Ligand. This prevents the RANK-Ligand from binding to pre-osteoclasts, and thus prevents them from maturing into osteoclasts. The effect is that the bone resorption process is slowed down, and the body has more time to build up and strengthen its bones.

The body makes a substance called osteoprotegerin that does a similar thing to Prolia by preventing pre-osteoclasts from maturing into osteoclasts. In some patients with osteoporosis, this substance is found in lower concentrations and this is partly why their bones break down too quickly.

Patients taking Prolia should talk to their doctor if they are concerned about any side effects.

The most common side effect of this medication are rashes and issues with the skin.

Patients should let their doctor know if they develop a rash while taking Prolia, develop jaw pain, or experience muscle cramps, twitching or weakness.

Possible side effects include:

• Rash – Prolia can cause a rash, itching, or dry skin.
• Muscle & bone pain – Prolia can cause bone, muscle, or joint pain
• Low calcium – Prolia can very rarely lower the calcium in the blood. Patients should tell their doctor if they develop:
  • Tingling in the hands, feet, or around the mouth
  • Muscle cramps or twitching
  • Muscle weakness
• Jaw problem – Prolia has very rarely been associated with a jaw problem called osteonecrosis

Prolia should not be taken during pregnancy or breastfeeding. Patients who become pregnant should stop taking this medication and contact their doctor.

People who should NOT take Prolia include:

• Those allergic to Prolia or any ingredient in the medicine
• Pregnant or breast-feeding women

Anyone who becomes pregnant while taking Prolia should notify their doctor immediately.

Patients taking Prolia should call their doctor if they feel sick and want to stop, or if they are concerned about any side effects.

Other reasons to call a doctor while taking Prolia include:

• Tingling in hands, feet or around mouth
• Becoming pregnant or planning pregnancy
• New severe pain in the jaw
• Muscle cramps, pain, or weakness
• Fever or possible infection
