🩺 Clinical
Belladonna alkaloid combinations and phenobarbital are used to relieve cramping pains in conditions such as irritable bowel syndrome and spastic colon. They also are used with other medicine to treat ulcers. These medicines decrease the motion of the stomach and intestines and the secretion of stomach fluids, including acid. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Read the full MedlinePlus article ↗Phenohytro is an unapproved prescription oral elixir that combines four active ingredients. It contains phenobarbital, a barbiturate typically used to calm the central nervous system, along with three anticholinergic agents (hyoscyamine sulfate, atropine sulfate, and scopolamine hydrobromide) that are commonly used to reduce spasms and secretions in the gastrointestinal and urinary tracts. This combination was historically used for conditions involving both nervous system overactivity and gastrointestinal cramping, though it is no longer marketed with current FDA approval.

🧭 About this NDC listing & data coverage
Listed without an FDA application
This product's marketing category indicates it is marketed without an approved FDA application (no NDA, ANDA, or BLA on file). Having an NDC does not by itself establish FDA approval — the NDC Directory is a listing system, not an approval decision. Approval-linked data such as Orange Book therapeutic-equivalence ratings therefore does not apply.

⚠️ Warnings ▾
WARNINGS Heat prostration can occur with belladonna alkaloids in high temperatures. Diarrhea may be an early symptom of incomplete intestinal obstruction, particularly in patients with ileostomy or colostomy. In this instance, treatment with this drug could be harmful.
PHENOHYTRO ® ELIXIR may produce drowsiness and blurred vision. The patient should be warned about engaging in hazardous work or activities requiring mental alertness, such as operating a motor vehicle or other machinery. Phenobarbital may decrease the effect of anticoagulants, and larger doses of the anticoagulant may be necessary for optimal effect.
When phenobarbital is discontinued, the dose of the anticoagulant may have to be decreased. Phenobarbital may be habit forming and should not be administered to patients who are susceptible to addiction or to those with a history of physical and/or psychological drug dependence. Barbiturates should be used with caution in patients with hepatic dysfunction.
🤒 Adverse Reactions ▾
ADVERSE REACTIONS Call your doctor for medical advice about side effects. Adverse reactions associated with anticholinergics and/or anticonvulsants are: dry mouth; tachycardia; urinary hesitancy and retention; palpitation; blurred vision; prolonged pupil dilation; cycloplegia; increased ocular tension; loss of taste sense; headache; nervousness; drowsiness; weakness; dizziness; insomnia; nausea; vomiting; severe allergic reaction or drug idiosyncrasies, including anaphylaxis, hives and/or other dermal manifestations; decreased sweating; impotence; suppression of lactation; constipation; bloated feeling and musculoskeletal pain.
Elderly patients may react with symptoms of excitement, agitation and drowsiness to even small doses of the drug. Phenobarbital may produce excitement in some patients, rather than a sedative effect. In patients habituated to barbiturates, abrupt withdrawal may produce delirium or convulsions.
To report SUSPECTED ADVERSE REACTIONS, contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

🧬 Clinical Pharmacology ▾
CLINICAL PHARMACOLOGY This drug combination provides phenobarbital combined with belladonna alkaloids in a specific, fixed ratio to provide anticholinergic/antispasmodic action and mild sedation. Phenobarbital is a barbiturate, nonselective central nervous system depressant. It is primarily used as a sedative hypnotic and also as an anticonvulsant in subhypnotic doses.
Atropine Sulfate, Hyoscyamine Sulfate, and Scopolamine are belladonna alkaloids classified as anticholinergic, antimuscarinic drugs. They act to inhibit muscarinic actions of acetylcholine at postganglionic parasympathetic neuron effector sites. These drugs are also used as antispasmodics due to their anticholinergic action.
They produce the effect in the body of reduced muscle spasms in the digestive or urinary tract, and reduced fluid secretions from certain glands or organs.
