There are six main categories: Over-the-counter (OTC) medicines (medicamentos isentos de prescrição or MIPs in Portuguese): cough, cold and fever medicines, antiseptics, vitamins and others. Sold freely in pharmacies. Red stripe medicines: sold only with medical prescription. Anti-allergenics, anti-inflammatories, and other medicines. Red stripe antibiotics: antibiotics are sold only with a "special control" white medical prescription with patient's copy, which is valid for 10 days. The original must be retained by the pharmacist after the sale and the patient keeps the copy. Red stripe psychoactive medicines: sold only with a "special control" white medical prescription with patient's copy, which is valid for 30 days. The original must be retained by the pharmacist after the sale and the patient keeps the copy. Drugs include anti-depressants, anti-convulsants, some sleep aids, anti-psychotics and other non-habit-inducing controlled medicines. Though some consider them habit inducing, anabolic steroids are also regulated under this category. Black stripe medicines: sold only with the "blue B form" medical prescription, which is valid for 30 days and must be retained by the pharmacist after the sale. Includes sedatives (benzodiazepines), some anorexic inducers and other habit-inducing controlled medicines. "Yellow A form" prescription medicines: sold only with the "yellow A form" medical prescription - the most tightly controlled, which is valid for 30 days and must be retained by the pharmacist after the sale. Includes amphetamines and other stimulants (such as methylphenidate), opioids (such as morphine and oxycodone) and other strong habit-forming controlled medicines. Biological medications are complex molecules of high molecular weight obtained from a biological source or biotechnological procedures and are divided by Anvisa into the following categories: Allergens: substances from animals or plants that can induce an IgE response or a type I hypersensitivity reaction Monoclonal antibodies: immunoglobulins derived from the same B lymphocyte clone, propagated in continuous cell lines
