A new day for acromegaly treatment is here.
MYCAPSSA is now FDA-Approved!

MYCAPSSA® (octreotide) delayed-release oral capsules is the first and only oral somatostatin analog (SSA) capsule for patients with acromegaly who responded to and tolerated treatment with octreotide or lanreotide.

It is an alternative to SSA injections, that can eliminate the need for injections and regularly scheduled appointments. With MYCAPSSA, you can manage acromegaly treatment comfortably and conveniently from home, or wherever you are.


MYCAPSSA capsules are clinically proven to effectively maintain normal IGF-I and GH levels in the majority of patients.

The safety and efficacy of MYCAPSSA was studied in two clinical trials with 183 patients living with acromegaly who previously responded to and tolerated SSA injectable treatment with octreotide or lanreotide.

In these clinical studies, MYCAPSSA was generally well tolerated. The most common side effects are headache, joint pain, nausea, weakness, diarrhea, and sweating a lot.


Now that’s a step in the right direction.

MYCAPSSA Patient Experience

“During the clinical trial for MYCAPSSA, I realized that managing my acromegaly with an oral medication helps me avoid the burden I used to feel each month as I got near my injection day. And of course, the pain. Not having to deal with the pain of the injection is a real blessing.”

“As part of a clinical trial for MYCAPSSA, my lifestyle changed dramatically. Being on an oral treatment, I can easily travel with my medication. I just put it in my pill box with the rest of my medication and hop on a plane. I can meet with family and friends who come into town and not worry about missing an activity because I have to go to the doctor’s office. I love the freedom of taking MYCAPSSA.”
