I understand there is another injection called sustane, but I looking more for a tablet or capsules to replace the injection as my wife is finding it untolerable to continue gestone. She has been taking for last 3 months. [/INST] Hi, Incomplete data like age of your wife, purpose of taking gemstone injection or any side effects occurring with its use? Yes, there are two equally effective oral progesterone formulations are available.
