Cognex Warnings and Precautions
Since there are a number of side effects that may occur with Cognex, warnings and precautions for the drug should be discussed with a healthcare provider before you begin treatment. Cognex may cause seizures, affect the heart, or worsen asthma symptoms. Tell your healthcare provider about all existing medical conditions you have and any other medications you are taking before using Cognex.
You should talk with your healthcare provider prior to taking Cognex® (tacrine hydrochloride) if you have:
- Heart problems
- Stomach or intestinal ulcers (or a history of such problems)
- Liver disease, such as liver failure, hepatitis, or cirrhosis
- Bladder problems
- Epilepsy or seizures
- An upcoming surgery
- 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 other 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 Cognex include the following:
- Cognex may affect the heart, possibly causing a dangerously slow heart rate. This is probably more common in people with heart conditions but can occur in people without any heart problems.
- Cognex may increase the production of stomach acid, increasing the risk of stomach or intestinal ulcers. If you have an ulcer (or a history of an ulcer), your healthcare provider should monitor you closely to make sure Cognex is not making these problems worse.
- Many people who take Cognex experience an increase in liver enzymes (which is found using a blood test). Often, this is usually mild and does not indicate any problems. However, it can be quite severe and may indicate liver damage. Your healthcare provider should monitor your liver enzymes frequently.
- Cognex can impair the bladder's ability to empty, causing difficulty urinating. Let your healthcare provider know if you develop any bladder problems while taking Cognex.
- It is possible that Cognex could cause seizures or make seizures worse. However, Alzheimer's disease itself may also cause seizures.
- Stopping Cognex (or decreasing the dose) suddenly can lead to a worsening of Alzheimer's symptoms.
- Cognex may cause a worsening of asthma symptoms. Check with your healthcare provider before taking Cognex if you have asthma.
- If you have a surgery planned, make sure to let your surgeon and anesthesiologist know you are taking Cognex, as Cognex can interact with some medications used during anesthesia.
- Cognex can potentially interact with several medications (see Cognex Drug Interactions).
- Cognex is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are not known (see Cognex and Pregnancy).
- It is not known whether Cognex 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 Cognex and Breastfeeding).
