Frequently Asked Questions about Eptoin

1. How to stop taking Eptoin?

Stopping Eptoin suddenly may cause rebound and non-stop seizures, among several other side effects. Withdrawing Eptoin should be done very slowly, only with professional guidance. It might take several weeks to months. Your physician will slowly taper the dose to as low as possible, or none at all, based on your condition and the dosage used till then.

2. Are Eptoin and phenytoin the same?

Yes, both Eptoin and phenytoin are the same. Eptoin is the brand name for the drug phenytoin and is manufactured by Abbott Labs India Ltd. Eptoin 100 tablets contain 100 mg of phenytoin. Before starting phenytoin, confirm the name and dosage with your physician.

3. Can Eptoin cause TB infection?

No, Eptoin does not cause TB infection.
Isoniazid is a drug used to treat TB infection. Seizures are a potential side effect. So, TB patients may sometimes experience seizures while taking isoniazid. These are completely reversible with medical intervention, which may involve using Eptoin for treating seizures. People may confuse the conditions and presume that TB, seizures, and eptoin usage are related. Whereas, seizures are a potential side effect of the TB treatment with isoniazid.

4. Can Eptoin tablets be given while breastfeeding?

Using Eptoin has not been proven to negatively impact infant growth and development during breastfeeding. According to research, children breastfed by mothers taking Eptoin showed higher IQs and developed verbal abilities at 6 years of age, when compared to non-breastfed children. However, inform your doctor if you are breastfeeding and are also taking other sedative anticonvulsants or psychotropic drugs. Combined use may cause infant sedation.

5. Can Eptoin tablets be taken along with sugar tablets?

One of Eptoin’s side effects is increased blood sugar levels or hyperglycemia. It may interfere with sugar tablets like Metformin and reduce their effectiveness in your body. As a precautionary measure, consult your diabetic doctor as well before starting Eptoin. You must discuss all the medications you are currently using with your doctor before they prescribe Eptoin.

6. Is Eptoin a sleeping pill?

No, Eptoin is not a sleeping pill.

No, Eptoin is not a steroid. It contains phenytoin, which belongs to a class of drugs called hydantoins which are approved to treat and prevent epilepsy and seizures such as tonic-clonic seizures, focal seizures, and other types. Steroids, on the other hand, are another class of drugs. They are artificial versions of hormones, designed to prevent inflammation.

9. Is Eptoin safe in pregnancy?
