Midol can generally be taken as 2 caplets every 6 hours, with a maximum of 6 caplets in a 24-hour period. This dosage applies to adults and children 12 years and older. It is important not to exceed this limit to avoid potential side effects or overdose. If symptoms persist or worsen, consulting a healthcare provider is advised. Also, do not take Midol for pain for more than 10 days unless directed by a doctor.
