The bathroom medicine cabinet actually is one of the worst places to keep medicine, according to Pitt's Drug Information and Pharmacoepidemiology Center (DIPC).

Storing medications in the bathroom or kitchen near sources of heat and moisture, such as a sink, shower, dishwasher or stove, increases the likelihood that the medicine may be altered. According to DIPC, it is very common for medicine to degrade or become ineffective due to the conditions in which it is stored. Heat and moisture are the primary culprits, because they prompt a reaction between many ingredients in drugs.

"If medicine is left exposed to the sun or other severe heat for just a few hours, it can significantly decrease its intended effectiveness," said Jodi Sullivan, a pharmacist at DIPC.

Generally, drugs should be stored in a cool dry area away from heat, moisture and direct sunlight. A dresser drawer is a good storage place. Parents, though, should be sure to keep medications safe from their children, according to DIPC.

Here are indications that medicines may have deteriorated: * Pills: Over-the-counter pain relievers and antibiotics deteriorate quickly when exposed to heat, according to DIPC.

To remain safe and effective, tablets must maintain their original size, shape, weight and color. Excessive powder or solid particles at the bottom of the container, cracks or chips on the face of a tablet or the appearance of crystals on the surface all indicate chemical deterioration of the product.

A distinct odor is another indication that a product probably has degraded and should not be used. Pills that are coated with a gelatin substance also have a tendency to become soft and stick together or harden and crack, all conditions that reduce a product's effectiveness.

* Ointments: The biggest problem with the improper storage or ointments is that they "bleed" or change consistency, according to DIPC, separating the active ingredients and making the product less effective.

* Emulsions: These include creams and hand lotions. When the temperature of these products fluctuates or goes too high, according to DIPC, the ingredients become less effective.

* Solutions: Liquids such as eye and ear drops or contact lens solutions should always remain clear. Discoloration is a sign of deterioration.
