Is any of this happening?
Be seen today
Contact a healthcare service promptly if you develop significant new muscle pain or weakness while taking cholesterol medicine.
Seek urgent assessment if this occurs with dark or cola-coloured urine, fever, or severe illness.
These symptoms are not proof that high cholesterol caused the problem, but they should not wait for a routine appointment.

Does any of this apply?
Book an appointment
Arrange a routine appointment if you have been told your cholesterol is high, have visible cholesterol deposits, or have a close relative with very high cholesterol or early heart disease.
Routine follow-up is also appropriate if you have questions about results, treatment, or possible medicine side effects.
Every sign above is quoted from the sofidex article on Hypercholesterolemia. If you are not sure, err upward — it is always reasonable to be checked.
