Why this happens
Collagen is a protein that needs stomach acid to be broken down into smaller pieces (amino acids) so your body can absorb it. Omeprazole works by reducing the amount of acid your stomach produces. With less acid available, your body may find it harder to fully digest and absorb the collagen supplement.
What you should do
You can continue to take both, but try to take them at different times. It is usually best to take your omeprazole first thing in the morning on an empty stomach (as prescribed) and take your collagen supplement at a different time of day, such as with a meal later in the afternoon, to give your body the best chance of absorbing it.

Tratamiento y medicación
Can I take Amlopadine and Aspirin together?
Taking amlodipine and aspirin together is generally considered safe, but there is a small chance that aspirin could slightly reduce how well amlodipine works to lower your blood pressure. Additionally, both medications can independently increase the risk of stomach irritation or bruising, though this is rarely a significant problem at standard doses.

Tratamiento y medicación
Can I take Aspirin and Nustendi together?
Taking aspirin with Nustendi (which contains bempedoic acid and ezetimibe) may slightly increase the levels of bempedoic acid in your blood. Additionally, if you are taking high doses of aspirin (over 325mg daily), there is a theoretical risk that it could interfere with how bempedoic acid works to lower your cholesterol.
