Platelet-rich plasma nasal injection for smell distortion
Treatments studied
Part of Brain & nervous system clinical trials.
This trial tests whether injecting a concentrated part of your own blood (platelet-rich plasma) into your nose can help improve a distorted sense of smell called parosmia. You will also do smell training at home, which is the current standard care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older.
- Your sense of smell has been distorted (not just lost) for at least 6 months but less than 2 years.
- The distortion started after a cold, flu, or other upper respiratory infection.
- You are not taking blood thinners (like warfarin or clopidogrel) and do not have a bleeding disorder.
- You are able to read and understand English and give your consent.

This trial tests if platelet-rich plasma injections can help people with long-term smell loss from aging or head injury. It aims to see if this treatment is safe and improves smell function.
This study tests if injections of platelet-rich plasma (a treatment made from your own blood) can help people who have lost their sense of smell. You may qualify if your smell loss is not caused by injury or blockages in your nose.
This study compares two ways to give platelet-rich plasma (PRP) to help people who have lost their sense of smell. PRP is a treatment made from your own blood that may help repair smell nerves.
This study tests whether a treatment made from your own blood (platelet-rich plasma) sprayed into the nose, with or without insulin, can help restore your sense of smell after an infection. You may be a good fit if smell training hasn't worked and your smell loss is recent.
This study tests whether using steroid nose drops combined with smell training helps people who lost their sense of smell after a viral illness. If you have ongoing smell problems after a cold or COVID, this treatment might help you regain your sense of smell.
This trial tests if steroid drops placed directly in the nose can improve smell in people with chronic sinusitis and a blocked smell area. It may help if you have had smell loss and sinus inflammation.
