Cogentin Injection (Benztropine)

Do’s

• Before using, inspect the injection solution for particles or discoloration. If either is present, discard the medication and don't use it.
• Use Cogentin exactly as prescribed by your healthcare provider, including dosage, frequency, and injection method (intravenous or intramuscular). The usual dosage ranges from 2 to 4 times a day or a single dose at bedtime.
• To minimize side effects, your healthcare provider might start you on a low dose and gradually increase it as needed.
• Use Cogentin consistently to experience the full benefits. Try to inject it at the same time(s) each day for better adherence.
• If using Cogentin for side effects from another medication, your healthcare provider might recommend taking it regularly or only as needed. For Parkinson's disease, your healthcare provider might adjust the dosage of other medications like levodopa alongside Cogentin.
• Tell your healthcare provider if you experience a decrease in the effectiveness of Cogentin over time.

Don'ts

• Don't increase your dose, use it more often, or use it for longer than prescribed by your healthcare provider.
• Don't suddenly stop taking Cogentin, as it can worsen your condition. Follow your healthcare provider's instructions for gradually reducing the dose when necessary.
• Don't hesitate to tell your healthcare provider if your condition doesn't improve or worsens after using Cogentin for a while.
