Modalert and Modvigil are both brand names for medicines that contain modafinil as an active ingredient. Modafinil is a drug that is mostly used to treat people who are too sleepy during the day because of narcolepsy, shift work sleep disorder, or obstructive sleep apnea. Off-label, it is also sometimes used to improve brain function and awareness in people who don't have sleep problems. Modalert and Modvigil both contain modafinil, but they are made by different drug companies, so there may be small changes in how they are mixed, how they are made, or the inactive ingredients that are used. Because of these changes, some people may have different general experiences or side effects.

You should know that picking between Modalert and Modvigil might depend on your taste or reaction since most people don't agree on which one is better. Some people may find that one brand works better for them in terms of how well it works, how well it takes, or how much it costs. If you have been given Provigil or are thinking about using it to improve your brainpower, you should talk to a doctor or nurse about the right dose and any possible side effects or combinations with other drugs you may be taking. Also, buying medicines from trustworthy sources is important to make sure they are safe and of good quality.
