Tegrital CR 300 Composition

Carbamazepine (300 mg, controlled release): an antiepileptic that reduces abnormal electrical activity in nerve cells.

What Is Tegrital CR 300 Used For?

Epilepsy and seizures
Trigeminal neuralgia (severe facial nerve pain)
Nerve pain such as diabetic neuropathy, and some mood disorders when other medicines have not worked, as decided by a specialist

How It Works

Carbamazepine steadies overactive nerve cells in the brain so that seizures and nerve pain signals are reduced. The controlled-release form releases the medicine slowly through the day.

How to Take It

Take it at the same time each day, with or without food, swallowed whole. Do not chew, crush or break the tablet. Your doctor may raise the dose gradually. Benefit may take 1 to 2 weeks. Never stop it suddenly, and do not miss doses, because this can bring on seizures.

Possible Side Effects

Common side effects include:

Dizziness, unsteadiness or poor coordination
Drowsiness
Nausea or vomiting
Blurred vision, dry mouth or constipation

Seek medical help at once for a skin rash, mouth sores, fever, low mood or thoughts of self-harm. Long-term use can also thin the bones.

Precautions and Who Should Be Careful

Tell your doctor about heart, kidney or liver disease, urinary problems or mental illness.
Regular blood tests may be needed before and during treatment.
Pregnancy: not generally recommended, but it may be prescribed if benefits outweigh risks. Speak to your doctor before planning pregnancy.
Breastfeeding: use with caution.
Do not drive until you know how it affects you.
Ask your doctor about alcohol.
Major interactions include itraconazole, warfarin, irinotecan, aprepitant and ulipristal. Tell your doctor about all medicines you take.

Key Points to Remember

Never stop carbamazepine suddenly or skip doses.
A new skin rash needs urgent medical attention.
Regular blood tests are part of safe treatment.

When to Contact a Doctor

Any new skin rash, blistering or mouth sores
Fever, sore throat or unusual bruising
Low mood or thoughts of self-harm
More frequent seizures or feeling very unsteady

Practical Tips

Set a daily alarm so you take it at the same time.
Do not drive or use machinery until you know how it affects you.
Keep a seizure or pain diary for your doctor.
Include calcium and vitamin D in your diet to protect your bones if you are on it for long.
