What Are the Side Effects of Journavx?

Journavx was generally safe and well tolerated in the clinical trials.

The most common adverse reactions were itch, muscle spasms, and rash.

Additionally, people taking Journavx should avoid grapefruit and grapefruit juice as they can reduce its effectiveness.
