At least 2 weeks before you start treatment with BEKEMV, your doctor will administer a vaccine against meningococcal infection if it was not previously administered or if your vaccination is outdated. If your child is below the age of vaccination or if you are not vaccinated at least 2 weeks before you start treatment with BEKEMV, your doctor will prescribe antibiotics to reduce the risk of infection until 2 weeks after you have been vaccinated.
Your doctor will administer a vaccine to your child aged less than 18 years against Haemophilus influenzae and pneumococcal infections according to the national vaccination recommendations for each age group.
The treatment will be given by your doctor or other health care provider by infusing a dilution of the BEKEMV vial from a drip bag through a tube directly into one of your veins. It is recommended that the beginning of your treatments, called the initial phase, will extend over 4 weeks, followed by a maintenance phase.

Children and adolescents with PNH or aHUS and who are 40 kg weight and over are treated with the adult dosing.
Children and adolescents with PNH or aHUS and who are under 40 kg weight require a lower dose based on how much they weigh. Your doctor will calculate this.
