Why is this medication prescribed?

Hyoscyamine is used to treat gastrointestinal (GI) tract illnesses’ accompanying symptoms. The motion of the stomach, intestines, and the discharge of stomach contents, particularly acid, are all reduced as a result of how it operates. In addition to treating bladder spasms, peptic ulcer disease, diverticulitis, colic, irritable bowel syndrome, cystitis, and pancreatitis, hyoscyamine is also used to treat colic. In addition to treating some cardiac disorders, Parkinson’s disease, and rhinitis (a runny nose), hyoscyamine can also be used to lessen excessive salivation.

How should this medicine be used?

Three different oral dosage forms of hyoscyamine are available: tablets, extended-release (long-acting) capsules, and liquid. The drink and tablets are often consumed three or four times a day. Typically, two doses of the extended-release capsules are taken each day. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Hyoscyamine should be taken as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not split, chew, or crush the extended-release pills; instead, swallow them whole.

Hyoscyamine manages GI tract problems’ symptoms but does not treat the underlying conditions. Hyoscyamine should still be used even if you feel OK. Without consulting your doctor, do not stop taking hyoscyamine.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Store it away from excessive heat and moisture at room temperature (not in the bathroom).

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at http://goo.gl/c4Rm4p for additional information.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at https://www.poisonhelp.org/help. Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

What other information should I know?

Keep all of your appointments with your physician and the lab.

No one else should take your medication. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals. This list should be brought with you whenever you see a doctor or are admitted to the hospital. You should always have this information with you in case of emergencies.
