Aiyo sabar sabar, I know the feeling when your usual pharmacy suddenly habis stok! Try calling ahead to the bigger pharmacies in Penang like Guardian or Watsons at the malls, a few of us tried that and sometimes they can check their system and reserve for you, or suggest which outlet nearby still has it. You could also ask your doctor or clinic if they can prescribe it or recommend where to get it, sometimes they know which pharmacies are still stocked better than we do!
