Interactions between your drugs

Moderate

macimorelin lonapegsomatropin

Applies to: macimorelin and lonapegsomatropin

GENERALLY AVOID: Drugs that may blunt the growth hormone response to macimorelin such as muscarinic antagonists (e.g., atropine), anti-thyroid agents (e.g., propylthiouracil), and growth hormone products may impact the accuracy of the macimorelin diagnostic test.

MANAGEMENT: Concomitant use of drugs that can blunt the response to macimorelin should generally be avoided. A sufficient washout period following discontinuation of these drugs is recommended prior to macimorelin administration. The prescribing information recommends discontinuing growth hormone products for at least one week before administering the macimorelin diagnostic test.

MANAGEMENT: Macimorelin should be administered after fasting for at least 8 hours.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.
