Patient's Query

Hello doctor,

Patient is a 59-year-old diabetic, having a rash on the knee probably insect bite from a bush. It is itchy and looks like a bruise. The rash is present for about a week. Patient is currently on Janumet 50/1g, Alkaline 24, and Spirulina capsules.

Hello,

Welcome to icliniq.com.

From your history, it is unclear what your concern is. It would advise you to attach a photo to guide you better. Since you are a diabetic, there might be slow healing and that is why a suspected insect bite rash is persisting. You can apply Fusidic acid cream twice daily to see if it subsides. It is an antibacterial cream. Kindly revert back with a picture.

Patient's Query

Thank you doctor,

Here are the photos. Please send an online prescription of the cream.

Hello,

Welcome back to icliniq.com.

I have seen the attached photographs (attachment removed to protect patient identity). It looks to be an infected insect bite reaction. Since you are a known diabetic, it is advice one course oral antibiotics for better healing and an antibiotic cream for local application. You can follow the medications. Take Tablet. Cefadroxil 500 mg twice daily for 5 days, Tablet. Pantoprazole 40 mg once daily, Fusdic cream (Fusidic acid cream) morning and afternoon after thorough cleaning of the wound, Fusibet cream (combination of Fusidic acid + Betamethasone 0.1%) on the surrounding unbroken inflamed skin, only in the night, Tablet. Paracetamol 500 mg twice daily (as an antiinflammatory to reduce the inflammation), Tablet. Cetirizine 10 mg one tablet in the night (if itching is present) Provided you have no prior allergy to the above-mentioned medications. Keep the wound dry and open most of the time, and closed if going outdoors to prevent the entry of the dust particles. These medications are to be taken for five days and to be reviewed with photos after five days.

Same symptoms don't mean you have the same problem. Consult a doctor now!
