The recommended starting Cognex dosage is 10 mg four times daily. Your healthcare provider will usually increase your dose to 20 mg four times a day after four weeks. If needed, he or she may further increase your Cognex dose up to 40 mg four times daily. Your liver enzymes should be monitored regularly during treatment.
The dose of Cognex® (tacrine hydrochloride) that your healthcare provider recommends will vary depending on a number of factors, including:
- Whether you develop high liver enzymes due to Cognex
- Other medications you may take
- Other medical conditions you may have.
As is always the case, do not adjust your Cognex dose unless your healthcare provider specifically instructs you to do so.
The starting Cognex dose for Alzheimer's treatment is 10 mg four times daily. After four weeks, your healthcare provider should usually increase the dose to 20 mg four times daily. If necessary, your healthcare provider may further increase your dose, up to a maximum of 40 mg four times daily.
Your healthcare provider should monitor your liver enzymes (using a simple blood test). For the first 16 weeks, he or she should check your liver enzymes at least once every two weeks. After 16 weeks, your liver enzymes should be checked at least once every three months. If you stop taking Cognex for more than four weeks, you must "start over" with the liver enzyme monitoring, going back to at least once every two weeks for 16 weeks.
If your liver enzymes increase to over twice the normal upper limit, you may need weekly liver enzyme checks and your Cognex dose may need to be reduced. If you develop very high liver enzymes, your healthcare provider may recommend that you stop Cognex, either temporarily or permanently. If you ever develop symptoms (such as yellow eyes or skin) along with high liver enzymes, your healthcare provider should recommend that you stop Cognex permanently.
