Pharmacist tips for Hyoscyamine

pharmacist
  • You can take hyoscyamine with or without food, but if it upsets your stomach, try taking it with food to help.

    • If you take antacids, take hyoscyamine before meals and the antacid after meals.

      • Hyoscyamine can cause your mouth to feel dry because it causes your body to make less saliva. Make sure to drink enough water when you're taking this medication.

        • Hyoscyamine can affect your ability to think, focus, and react. Don't drive, operate machinery, or do anything that requires concentration until you know how this medication affects you.

          • Hyoscyamine can cause your body to make less sweat. This can cause your body to overheat more easily in hot temperatures and make you more thirsty. Make sure to drink enough water and stay hydrated while taking this medication.

            • Different brands and formulations of this medication may be used in children of different ages. Discuss with your child's healthcare provider about which brand and dosage form is best for your child.

              Tips on how to take hyoscyamine:

              • For the immediate-release and extended-release tablets: Swallow the tablets whole. Don't crush, chew, or split the tablets. If you're having trouble swallowing the tablets, talk to your provider about switching you to a different formulation of hyoscyamine.

                • For the sublingual tablet: Take the sublingual tablet by placing the tablet under your tongue and allow it to dissolve. Don't eat, drink, or smoke while it's dissolving. Also, you can swallow your saliva, but don't swallow the tablet.

                  • For the dissolvable tablet (ODT):, make sure your hands are dry before handling the medication. Peel off the foil backing, and remove the tablet from the blister card. Don't try to push the tablet through the foil; this can damage the medication. Place the tablet on the tongue to let it dissolve, and swallow with saliva.

                    More tips for hyoscyamine liquid:

                    • The oral drops contains 0.125 mg/mL and the elixir contains 0.125 mg/5 mL. Double check your bottle and the prescribed dose to avoid accidentally taking the wrong amount.

                      • Store the medication bottle at room temperature and keep it in the original bottle to protect from light.

                        • Make sure to only use a medication dose cup, syringe, or dropper from the pharmacy to measure out your dose. Don't use household spoons because they aren't accurate and might cause you to take the wrong dose.

                            Hyoscyamine can sometimes change your mood, thoughts, or ability to think. It can cause symptoms such as confusion, memory loss, or feeling disoriented. It can also lead to agitation, seeing or hearing things that aren't really there (hallucinations), or euphoria. In serious cases, it can also lead to a coma. Typically, these symptoms go away in 12 to 48 hours after you stop hyoscyamine. Please let your provider know right away if you experience any changes to your mood, thoughts, or behaviors.

                            • Risk factors: Heart problems | High blood pressure

                              If you have heart problems, such as heart failure, past heart attacks, or high blood pressure, let your provider know. Hyoscyamine can cause your heart rate to go up, which can worsen certain heart conditions. Let your provider know if you notice a change with your heart rate or feel symptoms such as a pounding or racing heart.

For example, you might experience the muscles of your gut slowing down, which can lead to constipation. Your body might produce less saliva or sweat, which can lead to dry mouth and feelings of thirst, and make it more likely for you to suffer a heat stroke. Hyoscyamine can also affect other functions, such as your heartbeat or vision. Let your provider know if you experience any changes to your bodily functions. If you have a fever, don't take hyoscyamine without asking your provider first.

                                If you've ever had a colostomy (or any similar procedures), let your provider know before you take hyoscyamine for diarrhea. Sometimes, diarrhea is a sign that you have a block in your gut, and taking hyoscyamine can be harmful.

                                If you think you have food poisoning, let your provide provider know before you take hyoscyamine. If you do, taking this medication can lead to a very dangerous problem called toxic megacolon.

                                Don't take hyoscyamine if you have severe ulcerative colitis. Large doses of hyoscyamine can slow the gut down to a stop. This can result in serious problems, like severe inflammation and swelling of the colon.
