Q 1. Can Laretol 1mcg injection have side effects?

Excessive Laretol 1mcg injection supplementation can lead to hypercalcemia (high blood calcium levels), resulting in symptoms like kidney stones, gastrointestinal issues, and calcium deposits in soft tissues. Proper dosing and medical supervision are crucial.

Q 2. How does Laretol 1mcg injection interact with parathyroid hormone (PTH)?

Laretol 1mcg injection and PTH work together to regulate calcium homeostasis. When blood calcium is low, PTH stimulates the production of Laretol 1mcg injection, which then helps increase calcium absorption from the intestines and prevents excessive calcium loss in the urine.

It's important to consult a healthcare professional before taking any supplements, including Laretol 1mcg injection. Self-supplementation without medical guidance can lead to imbalances and adverse effects.
