### Patient: Doctor, I have a big open wound on my knee. It's very painful and I am worried about infection. What medication should I take?
### Doctor: You will need a tetanus shot to protect against tetanus bacteria, followed by Bacitracin ointment to prevent infection. To help the wound heal, you can also apply Collagenase Topical and Becaplermin Topical. Additionally, cellulose can be used to help stop bleeding, and Collagen can be used to help promote tissue growth. If an infection has already set in, we will have to prescribe antibiotics such as Linezolid. The good news is that once we get the wound adequately disinfected, we can think about using Probucol, which can help to heal wounds like these.
