What is aspirin, caffeine, and dihydrocodeine (Synalgos-DC)?
Aspirin is a salicylate (sa-LIS-il-ate). It works by reducing substances in the body that cause pain, fever, and inflammation. Caffeine is a central nervous system stimulant. It relaxes muscle contractions in blood vessels to improve blood flow. Dihydrocodeine is related to codeine, an opioid pain medication (sometimes called a narcotic).
Aspirin, caffeine, and dihydrocodeine is a combination medicine used to treat moderate to severe pain.
Aspirin, caffeine, and dihydrocodeine may also be used for purposes not listed in this medication guide.
What are the possible side effects of aspirin, caffeine, and dihydrocodeine (Synalgos-DC)?
Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.
Like other narcotic medicines, dihydrocodeine can slow your breathing. Death may occur if breathing becomes too weak.
A person caring for you should seek emergency medical attention if you have slow breathing with long pauses, blue colored lips, or if you are hard to wake up.
Call your doctor at once if you have:
- noisy breathing, sighing, shallow breathing;
- a slow heart rate or weak pulse;
- fast or pounding heart rate, muscle twitching;
- confusion, unusual thoughts or behavior;
- infertility, missed menstrual periods;
- impotence, sexual problems, loss of interest in sex;
- symptoms of stomach bleeding--bloody or tarry stools, coughing up blood or vomit that looks like coffee grounds; or
- low cortisol levels-- nausea, vomiting, loss of appetite, dizziness, worsening tiredness or weakness.
Seek medical attention right away if you have symptoms of serotonin syndrome, such as: agitation, hallucinations, fever, sweating, shivering, fast heart rate, muscle stiffness, twitching, loss of coordination, nausea, vomiting, or diarrhea.
Serious side effects may be more likely in older adults and those who are overweight, malnourished, or debilitated.
Long-term use of opioid medication may affect fertility (ability to have children) in men or women. It is not known whether opioid effects on fertility are permanent.
Common side effects may include:
- dizziness, drowsiness;
- nausea, vomiting, constipation; or
- itching, mild rash.
This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
What is the most important information I should know about aspirin, caffeine, and dihydrocodeine (Synalgos-DC)?
Dihydrocodeine can slow or stop your breathing, and may be habit-forming. MISUSE OF THIS MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription.
This medicine is not for use in anyone under 18.
Taking this medicine during pregnancy may cause life-threatening withdrawal symptoms in the newborn.
Fatal side effects can occur if you use this medicine with alcohol, or with other drugs that cause drowsiness or slow your breathing.
What should I discuss with my healthcare provider before taking aspirin, caffeine, and dihydrocodeine (Synalgos-DC)?
Aspirin may cause stomach or intestinal bleeding, which can be fatal. This can occur without warning while you are taking this medicine.
You should not use this medicine if you are allergic to aspirin, caffeine, or dihydrocodeine, or if you have:
- severe asthma, asthma with runny nose and nasal polyps, or other breathing problems;
- a blockage in your stomach or intestines;
- hemophilia; or
- an allergy to NSAIDs (nonsteroidal anti-inflammatory drugs).
In some people, codeine (dihydrocodeine) breaks down rapidly in the liver and reaches higher than normal levels in the body. This can cause dangerously slow breathing and may cause death, especially in a child.
Do not give this medicine to anyone younger than 18 years old.
To make sure aspirin, caffeine, and dihydrocodeine is safe for you, tell your doctor if you have ever had:
- a bleeding or blood clotting disorder;
- a stomach disorder, especially an ulcer or bleeding;
- liver or kidney disease;
- asthma or other breathing disorder;
- a head injury or brain tumor;
- a seizure; or
- alcoholism or a drug addiction.
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. Taking aspirin during late pregnancy may cause bleeding in the mother or the baby during delivery.
Do not breast-feed while taking aspirin, caffeine, and dihydrocodeine. This medicine can pass into breast milk and cause drowsiness, bleeding, breathing problems, or death in a nursing baby.
How should I take aspirin, caffeine, and dihydrocodeine (Synalgos-DC)?
Follow all directions on your prescription label. Dihydrocodeine can slow or stop your breathing. Never use this medicine in larger amounts, or for longer than prescribed. Tell your doctor if the medicine seems to stop working as well in relieving your pain.
Dihydrocodeine may be habit-forming, even at regular doses. Never share this medicine with another person, especially someone with a history of drug abuse or addiction. MISUSE OF NARCOTIC MEDICINE CAN CAUSE ADDICTION, OVERDOSE, OR DEATH, especially in a child or other person using the medicine without a prescription. Selling or giving away aspirin, caffeine, and dihydrocodeine is against the law.

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 (Synalgos-DC)?
