Contraindications for Ixazomib Treatment

A contraindication refers to a condition or circumstance in which using a specific medication, such as Ixazomib, could result in harm. If you have any of the following conditions, Ixazomib may not be a safe option for you. It is essential to share your complete medical history with your healthcare provider before starting any new medication, including Ixazomib.

Severe liver disease: Ixazomib is processed by the liver. If liver function is significantly impaired, the medication may not break down properly, increasing the risk of side effects or toxicity.

Severe kidney disease: Reduced kidney function can cause Ixazomib to build up in the body, which may lead to a higher likelihood of serious side effects.

Allergy to Ixazomib or its components: If you have experienced an allergic reaction to Ixazomib or any of its ingredients, you should avoid this medication, as it could trigger a potentially life-threatening reaction.

Pregnancy: Ixazomib can harm an unborn baby and is generally contraindicated during pregnancy unless the potential benefits significantly outweigh the risks, which is rare. For more information, refer to the section on Ixazomib in Pregnancy.

Drug-to-Drug Interactions with Ixazomib

Ixazomib can interact with other medications, which may increase the risk of side effects or reduce the effectiveness of either Ixazomib or the other drugs. It is important to inform your healthcare provider about all medications you are taking, including prescription drugs, over-the-counter medications, vitamins, and herbal supplements. Below are some examples of medications that may interact with Ixazomib:

1. Rifampin (Rifadin): This antibiotic can decrease Ixazomib’s effectiveness by accelerating its breakdown in the body.
2. Carbamazepine (Tegretol): This medication, commonly used to treat seizures, can lower Ixazomib levels in the bloodstream, reducing its efficacy.
3. Phenytoin (Dilantin): Another seizure medication that can similarly decrease Ixazomib levels, making it less effective.
4. St. John’s Wort: This herbal supplement can reduce Ixazomib’s effectiveness by increasing the speed at which the body processes the drug.

Ixazomib in Pregnancy

Is it safe to take Ixazomib during pregnancy?

No, Ixazomib is not considered safe for use during pregnancy. It can harm an unborn baby, potentially causing birth defects or other serious complications. Women who are pregnant or planning to become pregnant should avoid Ixazomib unless a healthcare provider determines that the benefits outweigh the risks, which is uncommon. Women of childbearing age are typically advised to use effective contraception while undergoing Ixazomib treatment. If you become pregnant while taking Ixazomib, contact your healthcare provider immediately.

Ixazomib While Breastfeeding

Is it safe to take Ixazomib while breastfeeding?

It is not currently known whether Ixazomib passes into breast milk. However, because many medications can transfer through breast milk and potentially harm a nursing infant, it is generally recommended to avoid breastfeeding while taking Ixazomib. If you are breastfeeding or planning to breastfeed, consult your healthcare provider to discuss the safest options for both you and your baby.

Estimated Cost of Ixazomib

The cost of Ixazomib (Ninlaro) can vary depending on your location and the pharmacy you use.
