Glucosamine
About Glucosamine
Glucosamine is used to reduce pain, stiffness, and swelling in joints caused by osteoarthritis. Osteoarthritis is a degenerative joint disease in which the two ends of the joints come together due to the breakdown of a protective covering of cartilage.
Glucosamine contains glucosamine, which stimulates the formation and repair of the cartilage (the hard connective tissue that protects and covers the ends of long bones at the joints).
In some cases, you may experience constipation, diarrhoea, nausea, vomiting, or heartburn. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, please consult your doctor.
If you are allergic to shellfish, Glucosamine, or any other medicines, please tell your doctor. If you are pregnant or breastfeeding, please inform your doctor before taking Glucosamine. Do not give Glucosamine to children without a doctor’s advice.

Patients Concern
Disease/Condition Glossary
Osteoarthritis: It is a degenerative joint disease in which the two ends of the joints come together due to the breakdown of a protective covering of cartilage. Without this protective covering, the joints rub against each other, leading to pain and stiffness. Symptoms of osteoarthritis include pain, stiffness, inflammation, and tenderness. The main reason for osteoarthritis is age; the older you are, the more likely you are to develop it, making it a degenerative disease, as the joints wear out as a person ages. Other reasons include a past injury such as torn cartilage, dislocated joints, and ligament injuries.
