# Librela Solution for Injection for Dogs > Librela is a solution for dogs, given monthly. It targets nerve growth factor (NGF) to relieve osteoarthritis pain, increasing mobility and decreasing pain. Discreet cold-chain delivery  Accurate, precise dosing by weight Low overdose risk Shelf life: 3 years as packaged *Source: https://ashcroft4pets.co.uk/dog-medications/librela-solution-for-injection-for-dogs/* Librela is a monthly subcutaneous injection solution for dogs. Instead of reducing inflammation broadly like most OA pain relief, its active ingredient, bedinvetmab, binds to and inhibits NGF directly at the source of joint pain. It’s supplied in 1 mL vials across five strengths (5, 10, 15, 20, and 30 mg), with your vet selecting the right one for your dog’s weight. Dosage Indications - 5 mg: 5–10 kg - 10 mg: >10–20 kg - 15 mg: >20–30 kg - 20 mg: >30–40 kg - 30 mg: >40–60 kg Giant breeds over 60 kg: the vet draws multiple vials into one syringe for a single dose. **Cold Chain Delivery** Librela must stay refrigerated at 2–8°C. Orders ship in insulated medical packaging with ice packs via temperature-controlled courier. Someone needs to be home to receive it and move the vials into a fridge straightaway. Don’t freeze it.
