Generic: shark cartilage
an herbal product - treats Macular degeneration, Psoriasis, Arthritis, Pain, and Cancer
Interactions with Drugs
Shark cartilage products may contain high doses of calcium and may cause dangerously high blood calcium levels when taken with drugs known to increase blood calcium. Examples include long- term use of thiazide diuretics such as chlorothiazide (Diuril®) and antacids such as Tums®. In theory, shark cartilage may add to the effects of drugs and experimental agents that block new blood vessel growth. Based on one animal study, the cancer drug cisplatin and shark cartilage may act together against tumors, although there is a lack of reliable human supportive evidence.
Limited evidence suggests that shark cartilage may lower blood sugar levels. Caution is advised when using medications that may also lower blood sugar. Patients taking drugs for diabetes by mouth or insulin should be monitored closely by a qualified healthcare provider. Medication adjustments may be necessary.
Interactions with Herbs and Dietary Supplements
Shark cartilage products may contain high doses of calcium and may cause dangerously high calcium levels in the blood when taken with calcium supplements or antacids. Chondroitin sulfate and glucosamine may have additive effects when taken with shark cartilage.
Limited evidence suggests that shark cartilage may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.
