Tekturna: What Should I Tell My Healthcare Provider?You should talk with your healthcare provider prior to taking Tekturna® (aliskiren hemifumarate) if you have:
- Kidney disease, such as kidney failure (renal failure)
- High blood potassium (hyperkalemia)
- Any allergies, including allergies to foods, dyes, or preservatives.
- Pregnant or thinking of becoming pregnant
Specific Tekturna Warnings and PrecautionsWarnings and precautions to be aware of prior to taking Tekturna include the following:
- Pregnant women should not take Tekturna. This medication is a renin inhibitor, and medications that affect the renin-angiotensin system have been shown to cause serious problems when used during pregnancy (see Tekturna and Pregnancy).
- Tekturna can cause angioedema, a life-threatening reaction involving swelling of the lips, mouth, tongue, or throat. If you experience such symptoms, seek immediate medical attention.
- As with all blood pressure medications, Tekturna may sometimes cause low blood pressure (hypotension). Let your healthcare provider know if you develop signs of low blood pressure, such as dizziness, lightheadedness, or fainting.
- Make sure your healthcare provider knows if you have kidney problems before you take Tekturna. Your healthcare provider may need to monitor you more closely and, in some situations, this drug may not be the best choice for you.
- Tekturna rarely causes high blood potassium (hyperkalemia). However, this may be more common if you already have elevated potassium levels or if you take certain medications that also increase potassium levels (see Tekturna Drug Interactions).
- It is not known whether Tekturna passes through breast milk. Therefore, if you are breastfeeding or plan to start, discuss this with your healthcare provider prior to taking the drug (see Tekturna and Breastfeeding).
