Hello there.
I can understand your concern.
It's not so simple however to give medicine.
We need to examine her and a few basic tests will be required to know if there is any specific cause of the high blood pressure.
Get a ECG, CBC,RFT,
lipid profile done. And consult a MD. Physician in person for further evaluation and management.
Do not delay it and why are you not at a hospital already even when she is bleeding as you said.
Take her to a hospital right away.
Best regards.
Dr. Anil Kumar Jain.
