To make sure you can safely take hyoscyamine, tell your doctor if you have any of these other conditions:

How should I take hyoscyamine?
Take exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Your medication may come with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.
Hyoscyamine is usually taken before a meal. Follow your doctor's instructions.
Do not crush, chew, or open an extended-release tablet or capsule. It is specially made to release medicine slowly in the body. Breaking or crushing the pill would cause too much of the drug to be released at one time. Your doctor may want you to break an extended-release tablet and take only half of it. Follow your doctor's instructions.
Measure the oral liquid form of hyoscyamine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
The sublingual tablet form of this medication must be placed under the tongue, where it will dissolve. Do not swallow the sublingual tablet whole or wash it down with water. You may drink water after the pill has completely dissolved in your mouth.
Before using hyoscyamine oral spray for the first time, you must prime the spray pump. To do this, spray 3 test sprays into the air and away from your face. Prime the spray pump at least 1 test spray any time you have not used the oral spray for longer than 2 days. Spray until a fine mist appears.
After using the oral spray, try not to swallow right away. Do not rinse your mouth or spit for 5 to 10 minutes after using the oral spray.
Store this medication at room temperature away from moisture and heat.
Do not use hyoscyamine oral spray for more than 30 sprays, even if there is medicine still left in the bottle.
