Rx Note

Introduction During my time as a provisionally registered pharmacist rotating through Therapeutic Drug Monitoring (TDM), I realized that pharmacokinetic calculations were highly repetitive tasks. While pharmacokinetic modeling is useful, clinical decisions to withhold or adjust narrow therapeutic index drugs ultimately rely on the patient's clinical response. For instance, we monitor CRP, temperature, and white blood cell count for vancomycin and gentamicin, while actively tracking creatinine clearance changes for signs of toxicity. Mathematically, simply looking at a measured drug level often allows us to easily decide whether to withhold, adjust, or continue the current dose. This frequently renders subsequent pharmacokinetic calculations redundant. Consequently, I concluded that these calculations are primarily beneficial for dosage adjustments in toxicity cases. To streamline this process, I created an Excel-based TDM calculator in Excel sheet and OpenAsApp Link . The spreadsh...

Introduction "Time and tide wait for no man". We hear this constantly, whether from the CEO of Nvidia or from artificial intelligence companies pushing the narrative that AI is the new norm - one we must either embrace or be left behind by. Everywhere we turn, people are offering advice on how to optimize AI in our daily work. However, while I feel a sense of excitement about these advancements, I also harbour some serious reservations. The Illusion of the Infographic The most immediate impact I see in daily life is the lightning-fast generation of AI videos and infographics. Yet, far from being excited by these excellent graphics, I find myself a bit old-fashioned; I am not a person who loves visuals for the sake of it. In fact, it often takes more time to digest an infographic because we have to decipher the sequence and figure out the core message. More critically, infographics risk omitting crucial details that we might easily dismiss. We need to look beyond mere fascina...

Introduction In August 2018, I launched a self-initiated drug database project, called "RxLookup". My motivation stemmed from a lack of existing databases that met my daily workplace needs, combined with a desire for a more organized way to document my reading material. Furthermore, existing unofficial MOH Formulary mobile applications were infrequently updated and required users to pay a fee to remove advertisements. It wasn't until early March 2025 that the official MyFormulary app was launched by the Ministry of Health, Malaysia. About the Project As a full-time pharmacist at a government hospital in Malaysia, I built this self-initiated database on the foundation of the Malaysia Ministry of Health Medicines Formulary (MOHMF) . In daily practice, we frequently consult the MOHMF for crucial details such as prescriber categories , approved indications and procurement methods. The formulary also comprises a vast selection of cost-effective, essential medications. Howev...

Introduction Every year, tens of millions of ringgit worth of medicines dispensed by government health facilities remain unused by patients. This wastage creates unnecessary health risks in the home, where patients or family members may accidentally consume expired or incorrect drugs due to unclear or damaged labels. Furthermore, failure to discard medications properly can contaminate the environment when they are improperly disposed via household trash or the sewer system. In 2010, the Pharmaceutical Services Division, Ministry of Health Malaysia (MOH) has implemented the Return Your Medicines Program. Through this initiative, patients can return their unused or excess medicines to pharmacy counters or designated medicine return box at all pharmacy facility in MOH hospitals and health clinics for safe disposal. To strengthen these efforts, MyMediSAFE was launched in 2024 by the MOH, supported by various public and prviate organizations, to futher promote the safe disposal of medica...

Introduction In life, there are many days when we find ourselves lacking motivation and direction—especially when our hard work is dismissed or ridiculed by others. Sometimes, our best intentions are misunderstood or crushed by those around us. Just like anything else that requires maintenance, staying motivated and heading in the right direction takes deliberate effort. Having a curated set of quotes to read can provide that much-needed spark. This need inspired the creation of a famous quote generator: RxQuote . The Design Journey The development began by levergaing an AI agent to scaffold the core functionalities , which include: A smart shuffle button: A randomized shuffling mechanism designed so that a quote will not repeat until the entire stack has been displayed. A local data source: Fetching quotes directly from a built-in JSON file. An automated pipeline: A Node.js script that automatically parses an Excel sheet into the required JSON format. While building this, I realize...
