Thousands of people in Ireland depend on daily medications like statins, iron tablets, ibuprofen, and treatments for ADHD to maintain their health. However, a health expert has highlighted that many may not be getting the full benefit—simply because they’re taking their medicine at the wrong time of day, reports The Mirror.
Peter Thnoia, a pharmacist with more than two decades of experience and the founder of PillTime, an online pharmacy registered with the NHS, says that timing plays a crucial role in medication effectiveness, according to Mirror UK. He warns that not following instructions closely can reduce the drug’s effectiveness and increase the likelihood of side effects.
Peter explained: “Too often, people don’t read or fully follow the instructions that come with their medication – and that can have a real impact on how well those medicines work. Something as simple as taking a pill at the wrong time of day, or not alongside food when it’s needed, can reduce its effectiveness or even cause unwanted side effects, reports The Mirror.
“Building a consistent routine and understanding the ‘when’ as well as the ‘what’ of your medication is key to getting the best results for your health,” reports The Mirror.
Statins – avoid taking them at the wrong time
Statins, widely prescribed to manage cholesterol and prevent heart disease, are frequently mistimed by patients in Ireland. Medications such as simvastatin and lovastatin are proven to be more effective when taken at night, aligning with the body’s peak cholesterol production.
Peter said: “Many people take their statins in the morning, simply because it’s when they take the rest of their medication. But for certain types, such as simvastatin, research shows they work best when taken in the evening – when the body naturally produces more cholesterol. If you take them at the wrong time, you could be reducing their effectiveness without even realising it,” reports The Mirror.
Iron supplements – best taken before breakfast
The effectiveness of non-prescription drugs can also be compromised by poor timing. Iron tablets, for instance, are often taken during breakfast or with tea, yet dairy, coffee, and even cereals can block proper absorption.
Peter explained: “There are plenty of people who take morning supplements like iron tablets to ‘get them through the day’ – often gulped down quickly before heading to work. But iron is actually absorbed best on an empty stomach, and things like dairy, tea or coffee can block absorption. That’s why the best advice is to take iron tablets as soon as you get up, before breakfast,” reports The Mirror.
Other medications to be cautious with – including ADHD treatments
Levothyroxine (used for hypothyroidism)
This medication should ideally be taken first thing in the morning, with at least a 30-minute gap before eating or drinking, to improve how well it’s absorbed, reports The Mirror.
Ibuprofen and Naproxen (common painkillers)
These NSAIDs can irritate the stomach lining, so it’s recommended they be taken alongside food or a glass of milk to help reduce discomfort.
Certain ADHD medications, like methylphenidate
These stimulant medications can interfere with sleep if taken later in the day. Morning doses are typically advised to manage symptoms effectively during daytime hours while avoiding insomnia, reports The Mirror.
