Risks
Some proton pump inhibitors (like Nexium) can increase the risk of bone fractures, particularly with long-term use, high dosage, and in older adults. Consult with your doctor on ways to manage this risk, particularly regarding preventing bone loss, such as calcium and/or vitamin D supplements.
Older Adults
Older adults can be more susceptible to side effects such as bone loss and fractures, as well as C. difficile infection. Take extra care to monitor symptoms while taking Nexium.
Children
Children can be more susceptible to side effects of Nexium such as fever, cough, and nose/throat infections. Monitor children closely and contact your doctor for any concerns.
Pregnancy
This medication should only be used during pregnancy when it is essential. Consult your doctor if you want to take this medication while pregnant. Do not self-medicate with Nexium if you are pregnant or planning to be pregnant. If you become pregnant while taking Nexium, contact your doctor about what to do next.
Breastfeeding
It is not known if Nexium passes into breast milk, however, similar drugs do. The effects on a nursing infant are not clearly defined. Talk to your doctor if you are wanting to take Nexium while breastfeeding.
Interactions & Contraindications
Medications taken concurrently can sometimes interact with one another, which can affect the way that they function in the body or increase the risk of negative side effects. It is therefore important to keep track of your medication schedule (including both non-prescription and prescription drugs) and share this with your doctor. Do not change the dosage, stop or start taking any medication without first asking your doctor.
Drugs that may interact with Nexium are cilostazol, clopidogrel, methotrexate, rifampin, and St John’s wort. If you are taking any of these regularly, consult with your doctor before starting Nexium, as they may want to adjust your medication schedule to accommodate it.
Stomach acid is required for some medications to be absorbed correctly. As the active ingredient esomeprazole acts to reduce stomach acid, it can influence how these medications work. Examples include atazanavir, erlotinib, levoketoconazole, pazonpanib, and rilpivirine, among more. Always check with your doctor if you are unsure.
Esomeprazole is similar to omeprazole. Do not use omeprazole-containing products while taking esomeprazole.
