Merycet 30 Tablet is used to treat primary hyperparathyroidism, secondary hyperparathyroidism, and parathyroid-carcinoma. Primary hyperparathyroidism is a condition in which one or more parathyroid glands make too much parathyroid hormone (PTH). Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia (increase in the number of cells) of these glands. Parathyroid cancer is a rare disease in which malignant (cancer) cells form in a parathyroid gland's tissues.

Merycet 30 Tablet contains 'cinacalcet', which works by signalling the body to produce a less parathyroid hormone to decrease the amount of calcium in the blood.

In some cases, Merycet 30 Tablet may cause common side effects like vomiting, nausea, rash, headache, muscle pain, and diarrhoea. Most of these side effects do not require medical attention and gradually resolve over time. However, if the side effects persist or worsen, consult a doctor.

Hyperparathyroidism: Hyperparathyroidism is a condition in which one or more of your parathyroid glands become overactive and release (secrete) too much parathyroid hormone (PTH). This causes the levels of calcium in your blood to rise, a condition known as hypercalcemia. There are two types of hyperparathyroidism: primary and secondary.

Primary hyperparathyroidism: Primary hyperparathyroidism is a condition in which one or more parathyroid glands make too much parathyroid hormone (PTH). This can lead to the loss of bone tissue. Symptoms include constipation, frequent urination, increased thirst, joint pain, kidney pain (due to kidney stones), loss of appetite, and muscle weakness.

Secondary hyperparathyroidism: Secondary hyperparathyroidism is the medical condition of excessive secretion of parathyroid hormone (PTH) by the parathyroid glands in response to hypocalcemia (low blood calcium levels), with resultant hyperplasia (increase in the number of cells) of these glands. This disorder is primarily seen in patients with chronic kidney failure. Symptoms include muscle pain and weakness.

Parathyroid cancer: Parathyroid cancer is a rare disease in which malignant (cancer) cells form in a parathyroid gland's tissues. Symptoms include weakness, tiredness, nausea, vomiting, loss of appetite, weight loss for no known reason, being much more thirsty than usual, urinating much more than usual, and constipation.
