Nimodipine
About Nimodipine
Nimodipine is an oral medication used to reduce the risk of brain damage caused by a lack of blood flow after a bleeding event in the brain, specifically a ruptured aneurysm. It helps protect brain tissues from further injury by keeping blood vessels relaxed and open. This medication is crucial for supporting recovery during the critical weeks following a brain bleed.
To get the best results, you must take Nimodipine at strict, regular intervals throughout the day and night to keep steady levels in your body. It is best taken on an empty stomach, either one hour before or two hours after a meal. Sticking to a calm, low-stress environment and staying hydrated can also aid your overall recovery.
While taking Nimodipine, you may experience some common side effects, such as mild headaches, flushing, or dizziness. However, you must contact your doctor immediately if you face serious symptoms, such as an unusually slow heart rate, severe lightheadedness, or signs of an allergic reaction.
Do not take this if you have extremely low blood pressure or a history of severe allergic reactions to Nimodipine. Before starting, talk to your doctor if you have liver damage, heart disease, or if you are taking other medications for high blood pressure.
Avoid drinking grapefruit juice or alcohol while taking Nimodipine, as they can cause your blood pressure to drop to unsafe levels. If you are pregnant, breastfeeding, or an older adult, consult your doctor to ensure this medication is safe for your specific situation.

Patients Concern
Disease/Condition Glossary
Subarachnoid haemorrhage: Subarachnoid haemorrhage is bleeding in the subarachnoid space in the brain, usually bleeding from an aneurysm (a weakened area in the blood vessel). Subarachnoid space is the space where cerebrospinal fluid circulates, which protects the brain from injury. Due to haemorrhage, the blood supply to the brain is reduced, which leads to disruption of brain functions leading to its damage. The main symptom of subarachnoid haemorrhage is a sudden, severe headache. Other symptoms include neck pain, shoulder pain, confusion, seizures, irritability, double vision and rapid alertness loss.
FAQs
Nimodipine is used to prevent brain function changes after subarachnoid haemorrhage (bleeding around the brain) due to stroke or trauma.
Nimodipine works by relaxing the blood vessels, making it easier for the blood to flow. This helps prevent spasms in blood vessels, which lowers the risk of damage caused due to insufficient blood flow to the brain after bleeding due to any trauma or stroke.
Please do not stop taking Nimodipine without consulting your doctor. Continue taking Nimodipine for as long as your doctor has prescribed it to you. Do not be reluctant to speak with your doctor if you experience any difficulty while taking Nimodipine.
Light-headedness could be a side-effect of Nimodipine. Light-headedness is a sudden lowering in blood pressure leading to dizziness on standing. If you experience this, do not try to stand up suddenly or start walking, instead lie down and get up slowly only when you feel better.
Nimodipine might affect male fertility as it has been shown to decrease sperm density and motility. So, talk to your doctor if you are trying to father a child.
Nimodipine might decrease the number of platelets in the blood which could cause bleeding or bruising easily. Consult your doctor immediately if you experience unexplained bruising or bleeding.
Consult your doctor before taking multivitamin and multimineral medicines along with Nimodipine as they might decrease the effect of Nimodipine. Regular monitoring of blood pressure and dose adjustment may be required if taken together.
No, you should swallow the capsules whole. If you have trouble swallowing, or if the medication is being given through a feeding tube, a healthcare professional must extract the liquid using a specific oral syringe. Talk to your doctor.
Nimodipine must be kept at a steady level in your blood to continuously protect your brain's blood vessels from spasming. Skipping or delaying a dose can increase the risk of serious brain injury. Talk to your doctor.
No, you must avoid grapefruit and grapefruit juice. Grapefruit prevents your liver from breaking down the medicine, which can cause dangerously high levels of the drug in your body. Talk to your doctor.
Dizziness can occur due to a drop in blood pressure. Sit or lie down immediately, and stand up slowly to prevent falls. If the dizziness is severe or does not go away, contact your healthcare provider right away. Talk to your doctor.

The duration of treatment is strictly determined by your doctor, usually lasting for a specific period of weeks following a brain bleeding event. Do not stop taking it early. Talk to your doctor.
Absolutely not. Oral liquid preparations of Nimodipine must never be injected into your veins, as doing so can cause life-threatening complications. Always take it by mouth or through a feeding tube as instructed. Talk to your doctor.
