What is BC?

BC is a combination medicine used in adults and children at least 12 years old to temporarily relieve minor aches and pains such as headaches, muscle pain, cold, minor arthritis pain, menstrual cramps, and fever or body aches. This medicine is sometimes used in adults to relieve symptoms associated with hangover.

BC should not be used as a substitute for sleep.

BC may also be used for purposes not listed in this medication guide.

How should I take BC?

Use exactly as directed on the label, or as prescribed by your doctor.

BC is usually taken every 6 hours with a full glass of water.

Taking more than your recommended dose will not make BC more effective, and may cause serious side effects.

Take with food if BC upsets your stomach.

Limit the use of caffeine-containing medications, coffee, tea, cola, energy drinks or other sources of caffeine while taking this product.

Call your doctor if your symptoms do not improve, or if they get worse.

If you need surgery, tell the surgeon ahead of time that you are using BC. You may need to stop using the medicine for a short time.

Store at room temperature away from moisture and heat.

Warnings

Aspirin may cause stomach or intestinal bleeding, which can be fatal.

Aspirin can also cause a severe allergic reaction. Get emergency medical help if you have signs of an allergic reaction: hives, difficult breathing, swelling of your face, lips, tongue, or throat.

Limit the use of caffeine-containing medications, coffee, tea, cola, energy drinks or other sources of caffeine while taking BC. Using too much caffeine may cause nervousness, irritability, sleeplessness, and rapid heartbeats.

Using this medicine in a child or teenager with flu symptoms or chickenpox can cause a serious or fatal condition called Reye's syndrome.
