Finding an unidentified pill often causes immediate concern. Every prescription and over-the-counter solid medication distributed in the United States is required to carry a unique identifying mark. This system protects consumers by allowing for rapid and accurate drug identification in cases of accidental ingestion, mix-ups, or adverse events. Decoding these markings is a fundamental step in ensuring personal and public health safety.
Understanding Pill Imprint Codes
The United States Food and Drug Administration (FDA) mandates that all solid, oral dosage forms must be clearly marked with a code imprint. This requirement ensures that the drug product can be uniquely identified based on its physical characteristics. Complete identification relies on a combination of factors: the pill’s size, shape, color, and the specific printed code.
A standard imprint code is composed of two distinct parts. One part identifies the manufacturer or distributor, often represented by a letter, logo, or symbol. The second part is specific to the product, indicating the drug’s active ingredient and its dosage strength. This two-part system means a single mark like “i8” is only half of the full, unique identifier.
The Identity Behind the i8 Mark
When the imprint “i8” is found on a capsule, it corresponds to Hydroxyzine Pamoate 25 mg, a generic medication. This marking is associated with manufacturers like Ingenus Pharmaceuticals, and the full identification includes a manufacturer mark on the other side. The combination of the manufacturer’s mark and the “i8” number confirms the drug’s identity and strength.
Hydroxyzine Pamoate 25 mg is most often presented as a capsule. The capsule is generally green, or sometimes green and white, and has an oblong or cylindrical shape. These physical details, including the color and shape, are just as important as the alphanumeric code for correct identification.
How This Medication Works
Hydroxyzine Pamoate is classified as a first-generation antihistamine, though its applications extend beyond treating seasonal allergies. It is an anxiety-reducing medication with sedative properties, often prescribed for the short-term management of anxiety and tension. The drug is also commonly used to relieve itching (pruritus) caused by allergic conditions like chronic hives or contact dermatitis.
The medication functions by blocking histamine H1 receptor sites in the body. By blocking histamine, it reduces the symptoms of allergic reactions, such as swelling and itching. The calming effect on the central nervous system (CNS) is due to the suppression of activity in subcortical areas of the brain. This action provides the anxiolytic and sedative effects, helping to ease anxiety and promote relaxation.
Safety Guidelines for Found Pills
Finding any unidentified medication poses a potential risk and requires careful handling. Consuming a pill not specifically prescribed or dispensed to you is hazardous. This is important because a single imprint can sometimes correspond to different drugs from different manufacturers.
If an unidentified pill is found, secure it immediately out of reach of children and pets. The most responsible action is to contact a healthcare professional, such as a pharmacist, or the national Poison Control Center for guidance. These resources have access to comprehensive drug databases and can provide definitive identification and safety instructions.
