Ovidrel is a hormone that supports the normal development of an egg in a woman's ovary, and stimulates the release of the egg during ovulation.

HCG is used to cause ovulation and to treat infertility in women, and to increase sperm count in men. HCG is also used in young boys when their testicles have not dropped down into the scrotum normally. This can be caused by a pituitary gland disorder.

HCG may also be used for other purposes not listed in this medication guide.

Samsca (tolvaptan) reduces the level of a hormone that regulates the balance of water and salt (sodium) in the body. High levels of this hormone can cause an imbalance that results in low sodium levels and fluid retention.

Samsca is used to treat hyponatremia (low levels of sodium in your blood) in people with heart failure, and certain hormonal imbalances.

Samsca improves urine flow without causing the body to lose too much sodium as you urinate.

This medication guide provides information about the Samsca brand of tolvaptan. Jynarque is another brand of tolvaptan that is not covered in this medication guide.
