Carpal tunnel syndrome should improve within two to Avoiding or reducing the repetitive motions that put three months by taking 100 mg three times daily 400mg viagra plus sale. With both supplements buy 400mg viagra plus with amex, patients must keep taking the same dose, and include the supplements in their for life. The cost of shark cartilage for six months of therapy was estimated at $3,000–6,000 in 1997. The same amount of bovine cartilage was estimat- ed to cost about $1,000 at this time. While cartilage supplements do not appear to be harmful, persons who are considering them as a cancer treatment should not use them as their sole form of ther- apy and should consult their doctor before taking them. Persons who are considering chondroitin as a treatment for joint pain should be careful not to diagnose them- selves. They should check with their physician to be sure that the pain is caused by osteoarthritis. Although chondroitin appears to be helpful in treating osteoarthritis, it is not useful for these other conditions. Shark cartilage can cause hypercalcemia (excessive amounts of in the body) when taken at the rec- Center for Alternative Medicine Research in Cancer Home Page. Some patients taking chondroitin have been Beth Kapes known to experience nausea and or bloating. Odle Chondroitin sulfate is not known to cause any sig- nificant interactions with other medications. One re- searcher, however, has suggested that chondroitin might increase the effect of anticoagulant drugs and should probably not be used in combination with them.
