Distinctive lettering can be used by manufacturers to make it harder to confuse two drugs with similar names. Lamisil, on the left, is used to treat fungal infections. Lamictal, on the right, is prescribed for mood disorders. If one has a fungus infection but takes Lamictal, one risks experiencing the side effects of anti-depressants, which range from dizziness to kidney and/or liver damage. Taking Lamisil instead of Lamictal risks leaving a mood disorder untreated. (Institute for Safe Medication Practices)
