severe or uncontrolled asthma; or
a stomach condition called paralytic ileus.

epilepsy or other seizure disorder;
abnormal curvature of the spine that affects breathing;
a stomach or intestinal disorder;
problems with your pancreas, thyroid, or adrenal gland;

If you use dihydrocodeine while you are pregnant, your baby could become dependent on the drug. This can cause life-threatening withdrawal symptoms in the baby after it is born. Babies born dependent on habit-forming medicine may need medical treatment for several weeks.

How should I take acetaminophen, caffeine, and dihydrocodeine?
Follow all directions on your prescription label. Never take acetaminophen, caffeine, and dihydrocodeine in larger amounts, or for longer than prescribed. An overdose can damage your liver or cause death. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Dihydrocodeine may be habit-forming. Never share this medicine with another person. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
If you need surgery or medical tests, tell the doctor ahead of time that you are using this medicine.
Do not stop using this medicine suddenly after long-term use, or you could have unpleasant withdrawal symptoms. Ask your doctor how to safely stop using the medicine.
Store at room temperature away from moisture and heat. Keep track of your medicine. Dihydrocodeine is a drug of abuse and you should be aware if anyone is using your medicine improperly or without a prescription.
Do not keep leftover opioid medication. Just one dose can cause death in someone using this medicine accidentally or improperly. Ask your pharmacist where to locate a drug take-back disposal program. If there is no take-back program, flush the unused medicine down the toilet.
What happens if I miss a dose?
Since this medicine is used for pain, you are not likely to miss a dose. Skip any missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose can be fatal, especially in a child or other person using the medicine without a prescription.
Overdose symptoms may include extreme drowsiness or insomnia, tremors, fast heart rate, pinpoint pupils, severe muscle weakness, vomiting, loss of appetite, stomach pain, dark urine, seizure (convulsions), blue lips, very slow breathing, or coma.

Do not drink alcohol. Dangerous side effects or death could occur.
This medication may impair your thinking or reactions. Avoid driving or operating machinery until you know how acetaminophen, caffeine, and dihydrocodeine will affect you. Dizziness or severe drowsiness can cause falls or other accidents.
Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose.
Acetaminophen, caffeine, and dihydrocodeine side effects
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

If you have this type of reaction, you should never again take any medicine that contains acetaminophen.

shallow breathing, slow heartbeat;
fast or pounding heart rate, feeling light-headed, fainting;
