Prostalyn (LEVETIRACETAM) capsules typically come in packs containing 10, 20, or 30 capsules, but the exact number can vary depending on the manufacturer and packaging.

Regarding the duration of treatment, it is very important to follow your doctor's instructions. Levetiracetam is usually prescribed for managing seizures, and the length of treatment depends on your specific condition, response to the medication, and medical advice.

Key points to remember:

• Always take the medication exactly as prescribed by your healthcare provider.
• Do not stop taking Prostalyn without consulting your doctor, even if you feel better.
• If you have any questions about your medication or its duration, discuss them with your doctor or pharmacist.

If you need more detailed information about your prescription or treatment plan, please consult your neurologist or prescribing doctor for personalized advice.
