Where on the thigh can you get rebif shots?

Rebif (interferon beta-1a) is formulated as a sterile solution in a prefilled syringe intended for subcutaneous (sc) injection. I am guessing that when you are injecting into the thigh you might be injecting into the muscle and that is why it is more painful.

Here is some more information.

How should I use Rebif?

Rebif is available in ready-to-use, pre-measured, pre-filled syringes and requires no needle assembly. Rebif is given as an injection under the skin or into a muscle. Your doctor, nurse, or other healthcare provider will give you this injection. You may be shown how to inject your medicine at home.

Do not self-inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes.

Rebif is injected into a muscle of the thigh, the outer surface of your upper arm, your stomach or buttocks. Do not use the area near your navel or waistline. Use a different site each time you inject (thigh, hip, stomach or upper arm). Do not inject Rebif into an area of your body where the skin is irritated, reddened, bruised, infected or abnormal in any way. This medication comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Use each syringe only one time. Throw away used syringes in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.
