The doctor prescribed me Ovestin globules, but I read the leaflet and this drug scared me.

You did not write what drug you are talking about. I suppose about the preparation Ovestin tagged with the question. All possible side effects are included in this leaflet, but this does not mean that you will experience all of them. Side effects must be detailed for legal and patient safety reasons. Ovestin is intended for topical use, and absorption into the blood is minimal. Therefore, neither clinically relevant interactions with other drugs nor an increased systemic effect should be expected. Your doctor prescribed these globules to improve your health and reduce your ailments. He decided that this would be the right solution in your situation. Unfortunately, I do not know what particularly frightened you, or what symptoms could potentially worsen, so I can only suggest that you follow the doctor's instructions.
