What is Subvenite?

If you're pregnant and you are a registered mother, your name could be included on the pregnancy registry to monitor the effect of the medication lamotrigine on the infant.

How to take Subvenite?

Follow the directions on the label of your prescription and read the medication guide or instructions sheets. Your doctor may alter the dosage. Make sure you take the medication precisely as directed. Injecting too much Subvenite before the beginning of treatment could increase the risk of developing a serious and dangerous allergic skin condition. You might require regular blood tests to ensure that your doctor is sure that you're getting the proper dosage. Extended release along with immediate release Subvenite is a good choice for treating various situations. Make sure to check your refills regularly to ensure that you've received the right size, color, shape, and form of the tablet. Make sure you use only the prescription dosage and form the doctor recommends.

If you decide to switch Subvenite to another seizure medication, be sure to follow the instructions of your physician regarding the dosage and timing of the medication. Take the tablet in one swallow and make sure you don't chew, crush, or break it. Follow and read carefully any instructions for use that are included with the dissolving tablet or the dispersible ones. Consult your physician or pharmacist if you have any questions about these directions. Don't stop taking Subvenite abruptly, even if you feel well. The abrupt stop can cause seizures. Follow the instructions of your physician when increasing your dosage. In the event of an emergency, be sure to wear or have a medical ID to alert others that you are taking seizure medicine. Subvenite can affect a drug screening urine test, and you might get incorrect results. Inform the laboratory personnel that you take this medication.

What happens if I overdose?
