Donnatal Information:

What is Donnatal?

Donnatal is a branded medication that contains phenobarbital, hyoscyamine, atropine and scopolamine. These last three medications are alkaloids that have antimuscarinic and anticholinergic properties that have an inhibitory effect on the parasympathetic nervous system. They help to treat irritable bowel syndrome and other intestinal disorders by slowing movement in the gastrointestinal tract and stopping spasms. Phenobarbital is a barbiturate medication that relaxes the body.

How do I take Donnatal?

Donnatal should be taken orally about once every 12 hours. It is normally taken about 30 minutes to an hour before meals. The dosage will vary by individual and condition. Some patients may require a dose every 8 hours. Always follow your doctors dosing instructions. If this medication causes you to have dry eyes, talk to your pharmacist about using artificial tears. Suck on hard candy or chew gum to relieve dry mouth. Eat a high-fiber diet to avoid constipation.

Before taking Donnatal, tell your doctor if:

  • You are allergic to any of the ingredients in Donnatal.
  • You are currently taking any other prescription or nonprescription drugs, vitamins or herbal supplements, especially other medications for your condition, sedatives, antidepressants, narcotics, cold or allergy medications, anti-anxiety medications, potassium and antiviral medications.
  • You have asthma.
  • You have emphysema.
  • You have chronically dry eyes or a dry mouth.
  • You have ulcerative colitis or an intestinal blockage.
  • You have difficulty urinating.
  • You have glaucoma.
  • You have an enlarged prostate.
  • You have Down’s syndrome.
  • You have kidney or liver disease.
  • You have heart disease.

What are the possible side effects of taking Donnatal?

Donnatal drug side effects include dizziness, drowsiness, weakness, blurred vision, dry eyes and dry mouth, constipation, nausea and bloating.  Tell your doctor if any of these side effects are severe or persistent. Serious side effects that should be addressed immediately include: unusual fatigue, pale skin, signs of infection, easily bruising or bleeding, eye pain or swelling, allergic reaction and vision changes.

What if I forget to take a dose of Donnatal?

If you miss a dose of Donnatal, take the missed dose as soon as you remember. If it is close to the time for your next dose, or if you have an empty stomach, skip the missed dose and continue on your regular dosing schedule. Do not take a double dose of Donnatal to make up for a missed one.

How do I store Donnatal?

Store Donnatal tightly closed in a light-resistant container at a room temperature between 68 and 77 degrees Fahrenheit. Keep this medication away from moisture, pets and children.

What happens if I overdose on Donnatal?

Signs of Donnatal drug overdose include nausea, vomiting, blurred vision, dilated pupils, hot and dry skin, dizziness, headache and central nervous system stimulation. If you think you or someone you know has overdoses on Donnatal, seek medical attention or call the Poison Control Center at 1-800-222-1222 immediately.


Donnatal can interact with alcohol and sedatives, including cold and allergy medications. Talk to your doctor about combining any of these drugs before using them.
