How long does statin therapy take to work for transient ischaemic attack?

A transient ischaemic attack is a warning that blood flow to part of the brain was briefly disrupted. Statins reduce the liver's cholesterol production and help lower low-density lipoprotein cholesterol. Over time, this can make fatty deposits in artery walls less likely to grow or rupture. The medicine supports prevention; it does not reverse the brain symptoms of a TIA that has already happened.

You may not feel a change when the medicine is working. Follow-up blood tests help the clinician check your response and decide whether the dose remains suitable. Blood pressure control, diabetes care, stopping tobacco and movement advice may be needed alongside the statin.

Take the statin at the prescribed time and keep taking it even when you feel well. If you miss a dose, follow the instructions supplied with your medicine rather than doubling the next dose. Tell your clinician about new muscle pain, weakness, dark urine, or medicines and supplements you use, because interactions can matter. Do not stop treatment on your own; arrange a review if side effects make it difficult to continue.

Call emergency services immediately if facial drooping, arm weakness, speech trouble, sudden vision loss, severe imbalance or new confusion appears, even if it clears. These can signal a stroke or another TIA and need urgent assessment. Severe muscle weakness with dark urine while taking a statin also needs prompt medical advice.

Ask when your cholesterol and liver tests should be checked, what symptoms should prompt a medication review, and how the statin fits with your blood pressure or blood-thinning treatment.
