Voltaren SR is a sustained released oral tablet consisting of a nonsteroidal anti-inflammatory drug called diclofenac. We carry both the brand choice, Voltaren SR, and its generic alternative, diclofenac SR, both available in 75mg and 100mg!

Voltaren SR tablets are taken to treat mild to moderate pain or other symptoms that may occur due to osteoarthritis or rheumatoid arthritis. These are both forms of arthritis, which affect the joints and causes tenderness, swelling, stiffness, and pain. Osteoarthritis occurs when the cartilage, which acts as a protective cushion for the joints, begins to wear away. This usually happens over time with age but can be caused by other factors such as joint injuries, repeated stress on the joint, certain diseases, and genetics. Rheumatoid arthritis occurs when the immune system – the body’s personal self defense mechanism – “malfunctions” and attacks the lining of the membranes that are located around your joints. This causes them to become thicker which can eventually damage and destroy the cartilage and bone within the joint. It is not known exactly why this happens, but there are some risks factors such as being female or obese or those who are middle-aged, have a family history, smoke, or have environmental exposures such as exposure to asbestos or silica.

Voltaren SR (diclofenac) is effective at treating certain forms of arthritis because as a NSAID (nonsteroidal anti-inflammatory drug), it is able to reduce the substances in the body that cause the pain and inflammation to occur.

Always follow directions given to you by your doctor. Instructions can usually also be found on the prescription or prescription bottle/container. Your doctor may need to occasionally change your dose and may need you to have frequent medical tests done while being treated with Voltaren SR.
