Product Description

Hydrocodone Watson 540 is in a group of drugs called narcotic pain relievers. Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone. The combination of acetaminophen and hydrocodone is used to relieve moderate to severe pain. Acetaminophen and hydrocodone may also be used for purposes other than those listed in this medication guide.

What it's used for:

Hydrocodone is a narcotic pain-reliever and a cough suppressant, similar to codeine. Hydrocodone blocks the receptors on nerve cells in the brain that give rise to the sensation of pain. Acetaminophen is a non-narcotic analgesic (pain reliever) and antipyretic (fever reducer). Acetaminophen works by elevating the threshold to pain, that is, in order for pain to be felt, greater stimulation of the nerves responsible for the sensation of pain is necessary. It reduces fever through its action on the temperature-regulating center of the brain. Frequently, hydrocodone and acetaminophen are combined to achieve pain relief, as in Vicodin and Lortab. It comes in the form of tablets, capsules and liquid. Among the many brands the dose of acetaminophen ranges between 500 and 750 mg, and the dose of hydrocodone ranges between 2.5 and 10 mg.

Follow the directions for using this medicine provided by your doctor. Take this medicine by mouth. This medicine may be taken with food if it upsets your stomach, although doing so may decrease its effectiveness. Consult your doctor or pharmacist about alternatives for decreasing nausea (such as antihistamines, or lying down for 1-2 hours with minimal head movement). Store this medicine at room temperature in a tightly-closed container, away from heat, and light. If you miss a dose of this medicine and you are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Possible side effects :

All medicines may cause side effects, but many people have no, or minor, side effects. Get emergency medical help if you experience serious side effects.

The most frequent adverse reactions include lightheadedness, dizziness, sedation, nausea, and vomiting. Other side effects include drowsiness, constipation, and spasm of the ureter, which can lead to difficulty in urinating. Hydrocodone can impair thinking and the physical abilities required for driving or operating machinery. Hydrocodone can depress breathing, and should be used with caution in elderly, debilitated patients and in patients with serious lung disease. Hydrocodone may be habit forming. Mental and physical dependence can occur, but are unlikely when used for short-term pain relief.

What if too much is taken :

If overdose is suspected, contact your local poison control center or emergency room immediately. Symptoms of overdose may include extreme drowsiness, weakness, or fatigue; loss of consciousness; slow, shallow, or abnormal breathing; persistent nausea, vomiting, or stomach pain; slow heartbeat; cold or clammy skin; unusual sweating; and yellowing of the eyes or skin.

What to avoid while taking this medication :

Combining alcohol and other sedatives with hydrocodone can lead to increased sedation and even cause confusion. Combining carbamazepine with acetaminophen may increase the risk of liver toxicity.

Tell your doctor if you regularly use any of these medicines, or any other narcotic pain medicine.
