Can you be on your own for a week?

From www.ready.gov 

If you take medication or use a medical treatment on a daily basis, be sure you have what you need on hand to make it on your own for at least a week. You should keep a copy of your prescriptions as well as dosage or treatment information. If it is not possible to have a week-long supply of medication and/or supplies, keep as much as possible on hand and talk to your pharmacist or doctor about what else you should do to prepare.

If you undergo routine treatments administered by a clinic or hospital or if you receive regular services such as home health care, treatment or transportation, talk to your service provider about their emergency plans. Work with them to identify back-up service providers within your area and the areas you might evacuate to. 
If you use medical equipment in your home that requires electricity to operate, talk to your health care provider about what you can do to prepare for its use during a power outage.

In addition, there may be other things specific to your personal needs that you should also have on hand. If you use eyeglasses, hearing aids and hearing aid batteries, wheelchair batteries, and oxygen, be sure you always have extras in your home. Also, have copies of your medical insurance, Medicare and Medicaid cards readily available. If you have a service animal, be sure to include food, water, collar with ID tag, medical records and other emergency pet supplies.
