Have you been prescribed Primidone? You must know these things

Have you or someone in your family been prescribed Primidone by your doctor for a condition that causes seizures, such as epilepsy? If so, it is very important to be fully informed about this medication. Because there are several things we need to be careful about when using this type of medication. So today, let's talk about this very simply, in a way that you can understand.

What is Primidone?

Simply put, Primidone is a medication that is used to control and prevent epilepsy, or what we commonly call 'seizures'. Sometimes the nerve cells in our brain become overactive. It's like a short circuit. That's when the seizure occurs. So what this medication does is calm down those overactive nerves. Then the seizure is controlled.

This medication may also be prescribed by doctors for other medical conditions. So if you have any questions about this, ask your doctor. In Sri Lanka, this medication is available under the brand name Mysoline.

Things you need to tell your doctor before starting medication

This is very important. Before you start taking this medicine, you should inform your doctor about any other medical conditions you have. Be sure to mention these things in particular:

  • Kidney disease: If you have any kidney disease.
  • Liver disease: If you have any liver disease.
  • Porphyria: This is a relatively rare condition. If you know you have this disease, be sure to tell your doctor.
  • Mental health issues: If you or anyone in your family has had depression, suicidal thoughts, or attempted suicide in the past, you should definitely mention it.
  • Allergies: Tell us if you have any allergies to Primidone, Phenobarbital, other seizure medications, any other medications, foods, or dyes.
  • Pregnancy: If you are pregnant, trying to get pregnant, or suspect you are pregnant.
  • If you are a breastfeeding mother: If you are a breastfeeding mother.

Based on this information, the doctor will decide whether this medication is suitable for you or not and the dosage to be given.

How should I use the medicine?

It is very important to follow these instructions when using this medicine.

  • Swallow this pill with a glass of water.
  • Take the prescribed dose, at the prescribed time, as prescribed by the doctor. Do not skip doses.
  • Even if you feel better, never stop taking this medication suddenly without your doctor's advice.

If you stop taking the medication suddenly, your condition may worsen, meaning you may have more seizures. Therefore, if you stop taking the medication, you should do so gradually, following your doctor's instructions.

What if the dosage of the medicine is increased? (Overdose)

If you think you have taken too much medicine, immediately call the National Poisons Information Centre at the Colombo National Hospital . Or go to the nearest hospital Emergency Unit (ETU) as soon as possible.

What if I miss a dose of medication?

If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and take your next dose at the scheduled time. Never take two doses at once to make up for a forgotten dose.

Other medications that may interact with this medicine

Primidone can interact with some other medications, so tell your doctor about all the medications you are taking (including vitamins and herbal remedies).

Things to keep in mind when taking medication

Be especially careful about birth control.

This is very important if you are a woman using birth control pills. Primidone may make your birth control pills less effective. This means that you may still be at risk of getting pregnant even if you are taking the pills. Therefore, be sure to talk to your doctor about using an additional form of birth control (such as condoms).

Sleepiness and attention

You may feel drowsy and dizzy when you first start taking this medicine. Therefore , avoid driving, working at heights, or using machines that require alertness until you get used to this medicine. If you are an elderly person, be careful when getting up from a sitting position. Otherwise, you may feel dizzy and fall.

This medication is not compatible with alcohol. Alcohol can interfere with the effectiveness of the medication and increase side effects (especially drowsiness).

Pay attention to mental well-being

This is a sensitive topic, but we need to talk about it. Some people may experience mood swings, anxiety, depression, or suicidal thoughts while taking this medication. If you are feeling this way, please don't suffer alone. Tell your doctor or someone you trust (family member, friend) right away. It is very important to get help as soon as possible.

Take care of vitamins

Long-term use of this medication may cause a decrease in vitamin D and folic acid levels in the body. Therefore, ask your doctor about eating a nutritious diet and taking additional vitamins if necessary.

👩🏽‍⚕️ Additional questions (FAQs)

Frequently Asked Questions (FAQs)

💬 Primidone (Mysoline) tablets are a very powerful medicine given for which disease?

This is one of the most effective and powerful drugs in the world, an old-generation (Barbiturate) that is used to control 'Grand Mal Seizures / Epilepsy', a brain-related disease, and Essential Tremor, a severe shaking disorder that occurs in old age! Doctors recommend this for those who have not responded to other seizure medications.

💬 How does this old drug (Primidone) go to the brain and stop seizures/tremors?

After you take this medicine, the liver breaks it into two pieces and converts it into the extremely powerful 'Phenobarbital'. When epilepsy occurs, nerve electrical signals are released without control. As soon as this pill (GABA-A receptors) reaches the brain, the gates that control the brain's electricity are completely opened and the calming chemical 'GABA' is sent throughout the brain. Then the 'short circuits/electrical shocks' in the brain stop immediately and the brain calms down.

💬 What are the dangers and side effects that people taking Primidone pills should be aware of?

The biggest danger and trouble is (oh my God!) the 'unbearable drowsiness and body numbness (Severe Sedation/Ataxia/Dizziness)' that comes with this. In the first few weeks of taking this, you will definitely have difficulty walking and falling/dizziness. The other most dangerous thing is that this (Suicidal thoughts) increases mental stress and causes 'suicidal' thoughts. Also, if you suddenly stop taking this pill, you can have a severe seizure (Status Epilepticus) that cannot be cured and die!
