Atropine is an anticholinergic sold in the U.S. under 3 brand and generic names, for bradycardia, heart arrest and poisoning. Below: what the FDA label says, every product that contains it, what the pills look like, and its recall record.
From the FDA label for Atropen (application NDA017106). Other atropine products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
ATROPEN is a single-dose autoinjector intended as an initial treatment of the muscarinic symptoms of insecticide or nerve agent poisonings; definitive medical care should be sought immediately. ( 2.1 ) Dosage is dependent on weight. ( 2.2 ) Dosage for Mild Symptoms: If the patient experiences two or more mild symptoms, administer one injection intramuscularly into the mid-lateral thigh. If, at any time after the first dose, the patient develops any of the severe symptoms, administer two additional injections intramuscularly in rapid succession. ( 2.2 ) Dosage for Severe Symptoms: If the patient is either unconscious or has any of the severe symptoms, immediately administer three injections intramuscularly into the patient's mid-lateral thigh in rapid succession. ( 2.2 ) 2.1 Important Administration Information It is recommended that three ATROPEN autoinjectors be available for use in each patient at risk for organophosphorus or carbamate poisoning; one (1) for mild symptoms plus two (2) more for severe symptoms [see Dosage and Administration ( 2.2 )] . Different dose strengths of ATROPEN are available depending on the patient's weight. ATROPEN should be used by persons who have had adequate training in the recognition and treatment of nerve agent or insecticide intoxication, but may be administered by a caregiver or self-administration if a trained…
The following serious adverse reactions are described elsewhere in the labeling: Cardiovascular Risks [see Warnings and Precautions ( 5.1 )] Heat Injury [see Warnings and Precautions ( 5.2 )] Acute Glaucoma [see Warnings and Precautions ( 5.3 )] Urinary Retention [see Warnings and Precautions ( 5.4 )] Pyloric Stenosis [see Warnings and Precautions ( 5.5 )] Exacerbation of Chronic Lung Disease [see Warnings and Precautions ( 5.6 )] Hypersensitivity [see Warnings and Precautions ( 5.7 )] The following adverse reactions associated with the use of atropine were identified in the literature. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Mild to moderate pain may be experienced at the site of injection. Common adverse reactions of atropine include dryness of mouth, blurred vision, dry eyes, photophobia, confusion, headache, dizziness, tachycardia, palpitations, flushing, urinary hesitance or retention, constipation, abdominal pain, abdominal distention, nausea, vomiting, loss of libido, and impotency.

A combination is a different drug — different dosing, different warnings. It is listed here so you can find it, not so you can substitute it.
From the FDA Enforcement database. A recall covers specific lots — not the drug as a whole.

None. None.
Pralidoxime: The signs of atropinization (flushing, mydriasis, tachycardia, dryness of the mouth and nose) may occur earlier than might be expected than when atropine is used alone. ( 7.1 ) Barbiturates: Atropine may potentiate the effect of barbiturates. ( 7.2 ) 7.1 Pralidoxime When atropine and pralidoxime are used together, the signs of atropinization (flushing, mydriasis, tachycardia, dryness of the mouth and nose) may occur earlier than might be expected when atropine is used alone because pralidoxime may potentiate the effect of atropine. Excitement and manic behavior immediately following recovery of consciousness have been reported in several cases. However, similar behavior has occurred in cases of organophosphate poisoning that were not treated with pralidoxime. 7.2 Barbiturates Barbiturates are potentiated by the anticholinesterases; therefore, barbiturates should be used cautiously in the treatment of convulsions resulting from exposure to atropine.
