LDL after a heart attack or stent.

No, not on your own. A normal report after a heart attack or stent usually means the medicine is doing its job, not that the problem has gone away. LDL tends to rise again once the tablet is stopped, and the risk to the artery rises with it. If you want the dose reviewed, or if cost or side effects are a worry, say so at your next visit. Your doctor will decide what to change.

It may be, but not all pain after a heart attack or stent comes from the tablet. Reduced activity, age, and other conditions also cause aches. First be clear about what kind of pain it is. Chest pain or pressure, or pain spreading to the arm, jaw, back, or shoulder, especially with sweating, breathlessness, or nausea, is not a statin side effect. For those symptoms, go to an emergency department or call local emergency services. For muscle aches in the limbs or back, do not stop the tablet quietly. Note where the pain is, when it started, and whether both sides are affected, and tell your doctor. There are usually options, and your doctor will decide between them, such as a change in dose, a different medicine, or a supervised pause and restart. If the muscle pain is severe, or comes with weakness, fever, or dark urine, seek medical care the same day.

Take it at the time your doctor advised, and at about the same time each day so that it becomes routine. Older statins were often advised at night, while several of the newer ones work equally well at any time of day, so follow your own prescription rather than changing the timing yourself. If you miss a dose, take it when you remember on the same day. If it is nearly time for the next one, skip the missed dose. Do not take two together to catch up.

Usually not enough on their own once coronary artery disease is proven. Much of the cholesterol in the blood is made by the liver rather than eaten, so food changes move the LDL number only so far, and slowly. Diet and regular walking still matter for weight, sugar, blood pressure, and fitness. The usual approach is both together, not one instead of the other. Do not stop or reduce the tablet to test whether diet alone is enough. If you want to try a stricter diet, tell your doctor first and let the next report show what it has achieved.

A repeat lipid profile is usually done some weeks to a few months after starting or changing a dose, then at longer intervals once the level is steady. Your doctor will set the timing for you. Whether you need to fast before the test depends on your reports and on the laboratory, so ask beforehand rather than assume either way. Using the same laboratory each time makes the values easier to compare, and noting the date beside each value shows the trend clearly.

Serious liver or kidney injury from statins is uncommon. Your doctor may check a liver blood test before or shortly after starting, and again if there is a reason. Statins are not a usual cause of kidney damage, and they are often continued in people who already have kidney disease, though the choice of medicine and the dose may be adjusted. Some symptoms should not wait for the next appointment. Yellow eyes or skin, dark urine, repeated vomiting, or severe tiredness or muscle weakness need medical assessment the same day. Do not simply stop the tablet and wait at home. Let a doctor examine you and decide what to do.
