Thank you for your questions. Yes, 1-2 years ago, we had medicine-shortage due to covid lockdown, one could only get max 3-mths of medications. The situation is not serious this year.
Aspirin is a common medication for seniors. Before covid and vaccination, I believe many seniors above 70 are already taking aspirin daily. Getting from govt pharmacy with hospital prescription is about 10cents a pill. While I don't work with medicines but I believe these are the main causes:-
1. The product should be Made-in-UK and UK has a shortage now because the raw-material is from China. China has supply disruption lately due to covid lockdown.
1. I believe this shortage is temporary just because they are subsidized medicine. They are still readily available at retail.
2. Malaysia has a huge shortage now, I speculate that suppliers also channeled some stockpile to help them?
If you don't feel like queuing in hospital pharmacy again, you can get these pills from retail pharmacy about 30cents each. Even shopee sells them because no prescription needed.
PS: When your dad reaches 80s or 90s, he will not be able to take blood thinners. After taking blood thinners for 1-3 decades, some people will develop internal bleeding which must stop aspirin ASAP or their blood-count will be too low. He will be offered an more exotic alternative, that is to install a LAA device in his heart.
