How should this medicine be used?
The combination of Two-Dyne comes as a capsule and tablet to take by mouth. It usually is taken every 4 hours as needed. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Two-Dyne exactly as directed.

This medication can be habit-forming. Do not take a larger dose, take it more often, or for a longer period than your doctor tells you to.
What special precautions should I follow?
Before taking Two-Dyne,
- tell your doctor and pharmacist if you are allergic to Two-Dyne, or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially anticoagulants (‘blood thinners’) such as warfarin (Coumadin), antidepressants, antihistamines, pain medications, sedatives, sleeping pills, tranquilizers, and vitamins. Many nonprescription pain relievers contain acetaminophen. Too much of this drug can be harmful.
- tell your doctor if you have or have ever had liver disease, porphyria, or depression.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking this medication, call your doctor.
- you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
- remember that alcohol can add to the drowsiness caused by this drug.
What special dietary instructions should I follow?
Two-Dyne may cause an upset stomach. Take this medicine with food or milk.
What should I do if I forget a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What side effects can this medication cause?
Two-Dyne may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- upset stomach
- stomach pain
If you experience any of the following symptoms, call your doctor immediately:
- skin rash
- difficulty breathing
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org

What other information should I know?
