Novolin N Drug Interactions

When certain medications are taken together with Novolin N, drug interactions could occur that may lead to low blood sugar. This effect can become life-threatening quite quickly, so it is important to check with your healthcare provider any time you start, stop, or change the dose of any medication. Some of the medications that may cause Novolin N interactions include salicylates, ACE inhibitors, and fibrates.

An Overview of Novolin N Interactions

There are numerous different Novolin® N (NPH insulin) drug interactions, too many to list entirely in this article.

Some of the medicines that may cause dangerously low blood sugar levels when combined with Novolin N include, but are not limited to:
