Pharmacist tips for Benztropine

pharmacist
  • Work closely with your prescriber when starting benztropine. Your dose will usually start low and increase slowly to find what works best for you.
  • You can take benztropine with or without food. If it upsets your stomach, try taking it with food to reduce nausea.
  • Benztropine can cause dry mouth. Drinking water, chewing gum, or sucking on hard candy can help. Tell your prescriber if it makes it hard to speak, eat, or swallow.
  • Benztropine can make it harder for your body to cool down. Be careful in hot weather because you can be at higher risk of overheating.
  • Benztropine can cause drowsiness or blurry vision. Avoid driving or using machinery until you know how it affects you.
  • Tell your prescriber about all the medications you take before starting benztropine. It can interact with some mental health medications or worsen certain conditions.
  • Benztropine can make it harder to urinate, especially if you have conditions like an enlarged prostate. Contact your care team if your symptoms worsen.
  • Pregnancy and breastfeeding: Talk to your prescriber before using benztropine if you’re pregnant, planning to become pregnant, or breastfeeding. It’s not known if it’s safe in these situations.

Risks and warnings for Benztropine

Benztropine 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.

Confusion and mental health effects

  • Risk factors: Older adults | Having a history of mental health conditions | Taking higher doses of benztropine

Some people might have trouble thinking clearly or feel confused when taking benztropine. When you first start it or if your dose is increased, avoid driving or doing tasks that require focus until you know how it affects you.

At higher doses or in some people, benztropine can cause confusion, excitement, or even hallucinations (seeing or hearing things that aren't there). If you have a mental health condition, it could worsen your symptoms, especially when starting or increasing the dose. Your prescriber will monitor you closely during this time.

Slowed gut movement

  • Risk factors: Taking tricyclic antidepressants, phenothiazines, or haloperidol

Before taking benztropine, let your prescriber know if you take tricyclic antidepressants, phenothiazines, haloperidol, or other anticholinergics. These medications can interact with benztropine and slow down or stop movement in your gut (called paralytic ileus), which can be serious. Contact your care team if you have stomach pain or discomfort.

Heatstroke

  • Risk factors: Hot weather | Chronic alcohol use | Manual labor in hot environment | Certain medical conditions

Benztropine can make it harder for your body to sweat and cool down. This can raise your risk of heat stroke. Stay hydrated and try to avoid being in the heat for long periods.

If you notice that you’re not sweating, you may be at risk for overheating. Watch for symptoms like feeling very hot, dizzy, or weak. Your prescriber may need to lower your dose if this happens. Get medical help right away if you think you’re overheating.

Muscle weakness

  • Risk factors: Taking higher doses of benztropine

This medication can sometimes cause weakness or trouble moving certain muscles, especially at higher doses. For example, if your neck has been stiff and suddenly relaxes, it might feel weak. If this happens, contact your prescriber, since your dose might need to be adjusted.
