Guide To Over-The-Counter Antibiotics
Gramicidin

Some over-the-counter throat lozenges contain gramicidin. This antibiotic is also found in topical ointments for skin wounds. In addition, certain products combine gramicidin with tyrocidine or other antibiotics. It can be combined with antiseptics as well. Most lozenges with gramicidin also contain an anesthetic to numb the throat. Individuals who have allergies to antibiotics or anesthetics should check with a doctor before use.
Sucrose, a type of sugar, may be used as an inactive ingredient in the lozenges. Diabetes patients may need to use sugar-free lozenges. Of course, individuals with sucrose allergies should not use this medicine. Patients who take sulfonamide antibiotics or anticholinesterases may require an alternate medication as well. Although it is safe to take one lozenge as needed to relieve throat pain, patients should never take more than eight lozenges per day. Children under twelve years old should not use these lozenges.
