Clinical PharmacologyR-Tanna Tablets combine the sympathomimetic decongestant effect of phenylephrine with the antihistaminic action of chlorpheniramine.
Indications and UsageR-Tanna Tablets are indicated for symptomatic relief of the coryza and nasal congestion associated with the common cold, sinusitis, allergic rhinitis and other upper respiratory tract conditions. Appropriate therapy should be provided for the primary disease.

WarningsUse with caution in patients with hypertension, cardiovascular disease, hyperthyroidism, diabetes, narrow angle glaucoma or prostatic hypertrophy. Use with caution or avoid use in patients taking monoamine oxidase (MAO) inhibitors, or within 14 days of stopping such treatment. This product contains an antihistamine which may cause drowsiness and may have additive central nervous system (CNS) effects with alcohol or other CNS depressants (e.g., hypnotics, sedatives, tranquilizers).
General: Antihistamines are more likely to cause dizziness, sedation and hypotension in elderly patients. Antihistamines may cause excitation, particularly in children, but their combination with sympathomimetics may cause either mild stimulation or mild sedation.
Information for patients: Caution patients against drinking alcoholic beverages or engaging in potentially hazardous activities requiring alertness, such as driving a car or operating machinery while using this product. Patients should be warned not to use this product if they are now taking a prescription monoamine oxidase inhibitor (MAOI) (certain drugs for depression, psychiatric or emotional conditions, or Parkinson's disease), or for 2 weeks after stopping the MAOI drug. If patients are uncertain whether a prescription drug contains an MAOI, they should be instructed to consult a health professional before taking such a product.
Drug interactions: MAO inhibitors may prolong and intensify the anticholinergic effects of antihistamines and the overall effects of sympathomimetic agents.
Carcinogenesis, mutagenesis, impairment of fertility: No long term animal studies have been performed with R-Tanna Tablets.
Pregnancy: Teratogenic effects: Pregnancy Category C. Animal reproduction studies have not been conducted with R-Tanna Tablets. It is also not known whether R-Tanna Tablets can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. R-Tanna Tablets should be given to a pregnant woman only if clearly needed.
Nursing mothers: R-Tanna Tablets should not be administered to a nursing woman.

Signs and symptoms: May vary from CNS depression to stimulation (restlessness to convulsions). Antihistamine overdosage in young children may lead to convulsions and death. Atropine-like signs and symptoms may be prominent.
