Therapeutic Drug Monitoring (TDM) is really important for managing patients who take many medications at once. It helps make sure that these patients get the best care possible.

1. Personalized Dosing:

With TDM, doctors can adjust medicine doses for each person. This is based on how their body absorbs and breaks down the drugs.

For example, patients taking warfarin, a medication to prevent blood clots, can have their INR levels checked. This helps doctors give them just the right amount of the medicine. This way, they can stop blood clots without causing any bleeding problems.

2. Reducing Drug Interactions:

TDM also helps keep track of drug levels in the body. This is really helpful because some patients take several medications at the same time.

By monitoring these levels, doctors can catch and avoid harmful interactions between drugs. For example, a patient on more than one anticonvulsant (medications for seizures) might need their doses changed based on how much of the drug is in their bloodstream.

In short, TDM helps make medication treatments safer and more effective, especially for patients who have complicated health needs.
