Memantine as a drug has been used clinically for many years and overall is a well tolerated drug. However it is important to say that clinical trials do have risks, potential benefits and potential drawbacks. Even if the trial medication under investigation is of benefit to some participants, it may not work for everyone.

People who are thinking of volunteering to participate in any clinical trial should learn about the risks and benefits before agreeing to take part. It is also important to note that taking part in a clinical trial like COBALT will not affect a person's routine care
