Protos contains the active ingredient strontium ranelate. It is only available with a doctor’s prescription.
Protos is used to treat severe osteoporosis, a condition that causes brittle bones. Protos should only be prescribed if other osteoporosis medicines are not suitable.
Every day, your body makes some new bone and destroys some old bone. Protos works by helping the body make more new bone. It also makes the body go more slowly when it destroys the old bone. This should help to make bone stronger.
Protos is available as a powder in individual-dose sachets. It should be mixed in water as described on the packet, and drunk straight away. It is best taken at least two hours before or two hours after food, or any medicines that contain calcium.
