Atropine is a fast-acting anticholinergic medicine that blocks acetylcholine at muscarinic receptors (the body's “rest and digest” signals), a long-familiar standby given by injection in emergencies and around surgery and used as eye drops or ointment to widen the pupil and relax eye focusing; it has been on the U.S. market since about 1971 and is available generically. Short-term use is usually well tolerated, though most people notice dry mouth, blurred vision, light sensitivity, a faster heartbeat or flushing. Watch for overheating, since atropine cuts down sweating, and get help for fever, no sweating in the heat, or confusion. Tell your care team first about heart disease, glaucoma, bladder trouble or chronic lung disease.
Clinical pearls
- Atropine eye drops can leave the pupil wide and near vision blurry for days, so carry sunglasses and wait to drive.
- After each drop, press the inner corner of the eye so less atropine reaches the bloodstream, especially in children.
- The ATROPEN goes into the outer thigh muscle, and emergency medical care is still needed right away after using it.
- After an atropine injection, pumping and discarding breast milk for 24 hours is suggested if you are breastfeeding.

What Atropine is used for
▾
Atropine is used in several forms, and each product has its own approved uses.
- Atropine Sulfate injection: temporary blockade of severe or life-threatening muscarinic effects, including reducing secretions (antisialagogue) and blocking vagal effects on the heart (antivagal).
- Atropine Sulfate injection: antidote for organophosphorus, carbamate, or muscarinic mushroom poisoning, depending on the label.
- Atropine Sulfate injection: bradyasystolic cardiac arrest or symptomatic bradycardia, depending on the label.
- Some older injection labels: pre-anesthetic use to reduce salivation and bronchial secretions, gut spasms (pylorospasm), ureteral and biliary colic (with morphine), and relaxing the gut during hypotonic radiography.
- ATROPEN Auto-Injector (intramuscular): poisoning by organophosphorus nerve agents and by organophosphorus or carbamate insecticides, in adults and children.
- Atropine sulfate eye drops and Isopto Atropine: mydriasis, cycloplegia, and penalization of the healthy eye in amblyopia.
- Atropine Sulfate eye ointment: mydriasis and/or cycloplegia, cycloplegic refraction, and pupil dilation in inflammatory conditions of the iris and uveal tract.
How Atropine works
▾
Atropine is an antimuscarinic. It blocks acetylcholine, a natural messenger, from acting on muscarinic receptors in glands, smooth muscle and the heart. This reduces secretions, relaxes smooth muscle, and can raise a slow heart rate.
The block is competitive, so it can be overcome when acetylcholine levels rise.
Atropine dosage
▾
Dosing depends on the product and the reason for use. Do not mix up regimens between products.
- Injection: usually given by a healthcare professional, most often into a vein, with the dose adjusted to heart rate, blood pressure and symptoms.
- ATROPEN Auto-Injector: a single-dose device injected into the outer thigh muscle. Three injections may be needed for severe symptoms, and emergency medical care should be sought immediately.
- Eye drops and ointment: applied in the eye as directed by your prescriber.
Follow your prescriber's instructions and the product label.

Read the label’s full dosing text
2 DOSAGE AND ADMINISTRATION 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 provider is not available. Only administer ATROPEN to patients experiencing symptoms of organophosphorus or carbamate poisoning in a situation where exposure is known or suspected. ATROPEN is a single-dose autoinjector intended as an initial treatment of the muscarinic symptoms of insecticide or nerve agent poisonings (generally breathing difficulties due to increased secretions); definitive medical care should be sought immediately. ATROPEN should be administered as soon as symptoms of organophosphorus or carbamate poisoning appear. In severe poisonings, it may also be desirable to concurrently administer an anticonvulsant (preferably a benzodiazepine) if seizure is suspected in the unconscious individual since the classic tonic-clonic jerking may not be apparent due to the effects of the poison. A cholinesterase reactivator such as pralidoxime may serve as an important adjunct to atropine therapy. Close supervision of all treated patients is indicated for at least 48 to 72 hours.

Atropine side effects
▾
Most side effects come from atropine's drying and speeding-up effects.
Common side effects
- Dry mouth
- Blurred vision
- Dry eyes and sensitivity to light
- Fast heartbeat or palpitations
- Flushing
- Dizziness and headache
- Constipation
- Trouble urinating
- Constipation, nausea, vomiting, abdominal pain
- Pain at the injection site
When to get medical help
- Get emergency help for signs of an allergic reaction, such as a spreading rash, swelling, or trouble breathing.
- Seek help for a very fast or irregular heartbeat, or chest pain.
- Seek help for overheating, high fever, or lack of sweating in hot weather or with exercise.
- Call right away for confusion, hallucinations, or delirium.
- Seek care for eye pain or sudden vision changes, which could signal acute glaucoma.
- Get help if you cannot urinate or have worsening stomach symptoms.
Atropine warnings and precautions
▾
- Heart effects: atropine can cause fast or irregular heartbeats and may worsen ischemia (poor blood flow to the heart) in people with a recent heart attack or severe coronary artery disease.
- Heat injury: reduced sweating can cause overheating, so avoid heavy exercise and heat.
- Acute glaucoma: it may be triggered in susceptible people.
- Urinary retention: risk is higher with bladder outflow obstruction.
- Pyloric stenosis: it may cause a complete blockage.
- Chronic lung disease: it can thicken airway secretions and form dangerous plugs.
- Allergic reactions: these include anaphylaxis.
Atropine interactions
▾
Two interactions are highlighted.
- Pralidoxime: atropine effects such as flushing, dilated pupils, fast heartbeat and dryness may appear earlier than expected, because pralidoxime can boost atropine's effect.
- Barbiturates: atropine may increase their effect, so they should be used cautiously for convulsions.
Interactions listed in the FDA-approved label
From the Atropine prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.
- Pralidoxime: Signs of atropinization (flushing, mydriasis, tachycardia, dryness of the mouth and nose) may occur earlier than 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, though similar behavior has occurred in organophosphate poisoning not treated with pralidoxime.
- Barbiturates: Barbiturates are potentiated by the anticholinesterases; atropine may potentiate the effect of barbiturates. Use barbiturates cautiously in the treatment of convulsions resulting from exposure to atropine.
Read the label’s full interactions text
7 DRUG INTERACTIONS 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.

Before taking Atropine
▾
- No contraindications are listed in one injection label.
- Tell your care team about heart disease, rhythm problems, or a recent heart attack.
- Mention glaucoma, bladder outflow obstruction, pyloric stenosis, or chronic lung disease.
- Tell them about any past allergic reaction to atropine.
- Pregnancy: data are limited, and life-sustaining treatment should not be withheld because of fetal concerns.
- Breastfeeding: traces pass into milk, and pumping and discarding milk for 24 hours after injection may reduce infant exposure.
- Children: nervous system effects may appear earlier and at lower doses.
- Older adults: dosing is cautious, usually starting low.
Atropine overdose
▾
Too much atropine can cause flushing, dry skin and mouth, fast heartbeat, widely dilated pupils, blurred vision, and a dangerously high fever. Confusion, hallucinations, delirium and coma can occur, and severe cases can lead to breathing depression, circulatory collapse and death. Treatment is supportive and may include oxygen or breathing support, cooling measures, bladder catheterization, fluids, a darkened room, and a benzodiazepine for severe agitation or seizures.
What Atropine does in the body
▾
Atropine can first slow the heart slightly, then speed it up as vagal control is blocked. It can reverse slow heart rhythms caused by vagal stimulation. It also reduces secretions and sweating, dilates the pupil, and can lower blood pressure when standing. In clinical doses it does not depress the central nervous system, but large or repeated doses may depress breathing.
How your body processes Atropine
▾
After an intramuscular injection, atropine peaks in the blood at about 30 minutes, and exercise can increase absorption. It spreads throughout the body, and about 44% is bound to plasma proteins. The half-life is about 2 to 4 hours, and it is more than doubled in children under 2 and adults over 65. Much of it is broken down in the liver, and 13 to 50% leaves unchanged in the urine.
How to store Atropine
▾
Store between 20ºC to 25ºC (68ºF to 77ºF); excursions permitted between 15ºC and 30ºC (between 59ºF and 86ºF) . Protect from light.

How widely Atropine is used (Medicaid data)
A general measure of how commonly Atropine is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Atropine is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Atropine prescribed? Of the 1,601 medications we measure, Atropine ranks #494 by Medicaid prescriptions — more than 69% of them.

Atropine side effects reported to the FDA (FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Atropine — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Atropine in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.
Atropine FDA approval history
How Atropine went from FDA review to the pharmacy shelf — the key milestones in its regulatory journey.
Source: Drugs@FDA.
Atropine recall history
A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.
The FDA’s enforcement reports list 5 Atropine recalls since July 2021. Two of them are still ongoing or began in the last six months and are listed first. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.

RxNorm is the U.S. National Library of Medicine’s normalized drug vocabulary. Its concept hierarchy can include forms that are not currently marketed; the status on each branch compares that concept with current FDA listings. RxCUIs identify vocabulary concepts, not individual packages or manufacturers.
