A commonly prescribed drug used to lower high cholesterol and ward off heart disease could cause some unpleasant side effects, including nosebleeds in certain patients. In England alone, an estimated 5.3 million people are on some form of statin, a type of medication designed to reduce cholesterol levels.

Atorvastatin is often given to those with high blood cholesterol, as well as individuals with a family history of heart disease or chronic health conditions such as diabetes or arthritis. According to NHS guidelines, atorvastatin is typically prescribed in tablet form, sometimes chewable for those who have difficulty swallowing.

High cholesterol can lead to blockages in the body's blood vessels, potentially causing serious and life-threatening complications like heart attacks and strokes. It's also a significant contributor to cardiovascular disease, which accounts for over a quarter of all deaths in England.

Despite its effectiveness in significantly reducing the risk of cardiovascular disease, atorvastatin is not without potential risks. Like all medications, some people may experience significant side effects when taking atorvastatin over a long period, while others may not experience any side effects at all.

The NHS advises that pregnant women should generally avoid atorvastatin due to potential risks to fetal development and birth defects. Consequently, if you fall pregnant while on atorvastatin, it's recommended that you cease taking it and consult a doctor.

There may be alternative medications available for those who are pregnant. Additionally, women might be advised to stop taking atorvastatin while breastfeeding, although it remains unclear how much of the drug passes into breast milk and whether it could cause side effects for a baby.

NHS guidance emphasises the importance of consulting a doctor if you're taking atorvastatin and are trying to conceive, are already pregnant, or are breastfeeding. You should also seek medical advice about atorvastatin if you:

• Have lung disease
• Have previously had a stroke caused by bleeding into the brain
• Have had muscular side effects when taking a statin in the past
• Have ever had an allergic reaction to atorvastatin or any other medicine
• Have a history of myasthenia gravis or ocular myasthenia
• Have an underactive thyroid
• Have ever had a muscle disorder (including fibromyalgia)
• Regularly drink large amounts of alcohol
• Have liver or kidney problems
