Methscopolamine is an anticholinergic medication that's used to treat peptic ulcers in adults. Although its brand name Pamine is no longer available, the generic methscopolamine tablets can be prescribed. This medication is taken by mouth before meals and at bedtime. Side effects can include dry mouth, blurry vision, and sleepiness.
Peptic ulcers (as add-on therapy)
Methscopolamine is an anticholinergic medication. It works by blocking a chemical called acetylcholine from attaching to its receptors in your stomach and intestines. This helps lower the amount of acid in the stomach and slow movement in the gut. These actions help with pain and discomfort from stomach ulcers (peptic ulcers).

Helps with pain and cramping due to stomach ulcers
Available as tablets taken by mouth
Take methscopolamine on an empty stomach 30 minutes before each meal and at bedtime.
Methscopolamine can cause sleepiness, dizziness, and blurry vision. These side effects 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.
Dry mouth is a possible side effect of methscopolamine because the medication can cause your body to make less saliva. Make sure to drink plenty of water while you're taking this medication to help relieve dry mouth.
It's also important to stay hydrated while you're taking methscopolamine because the medication can make it easier for you to overheat in hot temperatures. Methscopolamine can cause your body to make less sweat, which can affect how well your body can cool down.
Avoid alcohol while you're taking methscopolamine. It can make methscopolamine side effects like sleepiness worse, putting you at risk for falls or other accidents.
Don't take methscopolamine with other anticholinergics, like diphenhydramine (Benadryl) or glycopyrrolate (Robinul). These medications work similarly to methscopolamine, and they have similar side effects. Taking anticholinergic medications with methscopolamine can make side effects, like dry mouth, headache, and dizziness, worse. It can also lead to more serious side effects, like overheating, confusion, and agitation.
Talk to your care team if you want to take antacids for your stomach symptoms along with methscopolamine. Taking antacids at the same time as this medication can lower the amount of methscopolamine that's absorbed into the body, which can make it not work as well. Your care team can help you come up with a schedule to get the best results from both types of medications.
Methscopolamine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Risk factors: Age 65 years or older
Methscopolamine can cause changes to your autonomic nervous system, which controls the functions of your body that you don't have to think about. For example, methscopolamine can cause the muscles of your gut to slow down, which can lead to constipation. This medication can also make you have less saliva in the mouth, leading to dry mouth. Methscopolamine can also affect other functions, such as your heartbeat or vision. Let your healthcare team know if you experience any unusual and bothersome changes to your bodily functions while you're taking this medication.
Risk factors: Hot weather | In a warm environment
Methscopolamine can make you sweat less, which affects how well your body can cool itself down. This can put you at risk for fever, heat exhaustion, and heatstroke, especially when you're in a very warm environment. Don't take methscopolamine without asking your HCP first if you have a fever because the medication might make it worse.
Some early symptoms of heat exhaustion or heatstroke can include feeling thirstier, urinating less, having dry mouth, or feeling tired. But get medical help as soon as possible if these symptoms become severe or if you have additional symptoms like muscle cramping; faster or weaker pulse; confusion; hot, dry, red skin; or a very high fever.
Risk factors: Ileostomy or colostomy | Ulcerative colitis | Taking high doses of methscopolamine
In addition, don't take methscopolamine if you have severe ulcerative colitis. Taking large doses of methscopolamine can slow the gut down to a stop. This can lead to serious problems, like severe inflammation and swelling of the colon.
Risk factors: Taking too much methscopolamine
Make sure to take methscopolamine exactly as prescribed. Don't change your dose without talking to your prescriber. Taking too much methscopolamine can cause muscle weakness and paralysis. Stop taking methscopolamine and contact your prescriber right away if you notice muscle weakness or numbness in your body.
The typical dose is 2.5 mg or 5 mg by mouth 30 minutes before meals, and 2.5 mg or 5 mg at bedtime.
Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. When you are taking any of these medicines, it is especially important that your healthcare professional know if you are taking any of the medicines listed below. The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
Using medicines in this class with any of the following medicines is not recommended. Your doctor may decide not to treat you with a medication in this class or change some of the other medicines you take.
Using medicines in this class with any of the following medicines is usually not recommended, but may be required in some cases. If both medicines are prescribed together, your doctor may change the dose or how often you use one or both of the medicines.
