Note: I am not a doctor -
Yes, octreotide injections are much faster, however, the injector must be sure to completely dissolve the medication prior to injection.
Octreotide is usually recommended for those NET cancer patients who exhibit carcinoid syndrome symptoms.
Unfortunately, experience shows that both SSA's, [at some time in the future, with some patients] may not stop tumor progression and alternate treatment(s) is / are needed.
I would certainly question your provider as to why lanreotide is not available.
All the best to you,
