Alzheimers Home > Namenda Warnings and Precautions
Before using Namenda, warnings and precautions should be discussed with your healthcare provider. Certain medical conditions, such as liver or kidney disease, can increase the level of Namenda in the body, so be sure to tell your healthcare provider about any existing conditions you have before using the medication. Namenda warnings and precautions also extend to people who are allergic to any components of the drug.
You should talk with your healthcare provider prior to taking Namenda® (memantine hydrochloride) if you have:
- Epilepsy or seizures
- A severe urinary tract infection (UTI)
- Renal tubular acidosis, a kidney disorder
- Any other type of kidney disease, including kidney failure (renal failure)
- Liver disease, including liver failure, cirrhosis, or hepatitis
- Any allergies, including allergies to food, dyes, or preservatives.
Also, let your healthcare provider know if you are:
- Pregnant or thinking of becoming pregnant
Make sure to tell your healthcare provider about all medicines you may be taking, including prescription and non-prescription medicines, vitamins, and herbal supplements.
Warnings and precautions to be aware of prior to taking Namenda include the following:
- The medication has not been studied specifically in people with epilepsy or seizures. Since Namenda affects brain receptors and chemicals, it could cause problems in people with epilepsy. Check with your healthcare provider before taking it if you have a seizure disorder.
- Conditions that decrease the acidity of the urine can cause Namenda to build up to high levels in the body. Such conditions include severe urinary tract infections and renal tubular acidosis.
- The liver metabolizes Namenda, and the kidneys remove it from the body. Therefore, poor liver or kidney function may increase the level of Namenda in the body, possibly increasing the risk of Namenda side effects. Check with your healthcare provider before taking the drug if you have liver or kidney disease.
- Namenda can potentially interact with a few medications (see Namenda Drug Interactions).
- Namenda is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are not known (see Namenda and Pregnancy).
- It is not known whether Namenda 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 Namenda and Breastfeeding).
