Triacin-C (triprolidine HCl, pseudoephedrine HCl, and codeine phosphate syrup) is a combination of an antihistamine, an indirect sympathomimetic, and a narcotic antitussive (anti-cough), indicated for temporary relief of coughs and upper respiratory symptoms, including nasal congestion, associated with allergy or the common cold. Common side effects of Triacin-C include:
- dry mouth/nose/throat,
- disturbed coordination,
- drug rash,
- sun sensitivity,
- excessive sweating,
- low blood pressure,
- fast heart rate,
- numbness and tingling,
- blurred vision,
- double vision,
- ringing in the ears,
- loss of appetite,
- abdominal discomfort,
- urinary frequency,
- difficult urination,
- urinary retention,
- tightness of chest and wheezing,
- stuffy nose, and
- respiratory depression.
Dosage of Triacin-C is individualized according to the needs and response of the patient. The usual dose for adults and children 12 years and older is 2 teaspoonfuls (10 mL) every 4 to 6 hours, not to exceed 8 teaspoonfuls (40 mL) in 24 hours. Triacin-C may interact with monoamine oxidase inhibitors (MAOIs), other narcotic analgesics, alcohol, general anesthetics, tranquilizers, sedative-hypnotics, surgical skeletal muscle relaxants, other CNS depressants, guanethidine, bethanidine, methyldopa, and reserpine. Tell your doctor all medications and supplements you use. Tell your doctor if you are pregnant or plan to become pregnant before using Triacin-C; it is unknown how it will affect a fetus. The components of Triacin-C pass into breast milk. Because of the potential for adverse effects on a nursing baby, breastfeeding while using Triacin-C is not recommended. Withdrawal symptoms may occur if you suddenly stop taking Triacin-C.
