What is the limit of pseudoephedrine that an individual can purchase in a 24-hour period?

The limit of pseudoephedrine that an individual can purchase in a 24-hour period is 3.6 grams. This regulation is established to combat the misuse of pseudoephedrine in the illegal manufacturing of methamphetamine while still allowing individuals to access the medication for legitimate uses such as nasal congestion relief.

This limit applies to over-the-counter purchases and is enforced by law to help regulate the amount of pseudoephedrine that can be acquired without a prescription. Many states have similar laws reflecting the federal regulations regarding the purchase of products containing pseudoephedrine. Thus, individuals can only legally buy up to 3.6 grams in a single day, which helps to balance public health and safety concerns against the need for effective cold and allergy relief.
