Letira

Levetiracetam, the active ingredient in Letira, is an antiepileptic presented as a tablet for oral use. It treats partial‑onset, generalized tonic‑clonic and myoclonic seizures in patients with epilepsy.

GNH USA supplies Letira as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Levetiracetam is an antiepileptic medication used to control seizure activity.

- Partial‑onset seizures: reduces the frequency and severity of focal seizures. - Generalized tonic‑clonic seizures: helps prevent convulsive episodes across both brain hemispheres. - Myoclonic seizures: diminishes sudden muscle jerks associated with epilepsy.

Levetiracetam may cause a range of adverse reactions, from mild to serious.

Common Side Effects: - Drowsiness: feeling unusually sleepy or fatigued. - Dizziness: sensation of light‑headedness or unsteadiness. - Headache: mild to moderate cranial pain. - Irritability: increased mood swings or agitation. - Nausea: upset stomach or urge to vomit. - Nasal congestion: blocked or runny nose.

Serious or Rare Side Effects: - Severe allergic reaction: rash, swelling, or difficulty breathing. - Mood changes: depression, suicidal thoughts, or aggressive behaviour. - Blood disorders: low white blood cells or platelets. - Liver dysfunction: jaundice or elevated liver enzymes. - Skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.

Before initiating therapy, consider the following safety measures.

- Renal function: adjust dose if creatinine clearance is reduced. - Psychiatric history: monitor for mood alterations or suicidal ideation. - Pregnancy: discuss potential risks with a healthcare professional. - Breastfeeding: evaluate benefits versus possible infant exposure. - Concomitant CNS depressants: use caution as additive sedation may occur. - Store at ambient temperature: keep below 25 °C, protect from moisture, and retain in original packaging.

Levetiracetam can interact with other medicines, influencing efficacy or safety.

Major Interactions (Avoid): - Carbamazepine: may reduce levetiracetam plasma levels. - Phenobarbital: can lower levetiracetam concentrations. - Phenytoin: may decrease levetiracetam exposure.

Moderate Interactions (Monitor Closely): - Alcohol: may enhance central nervous system depression. - Sedative antihistamines: could increase drowsiness. - Other antiepileptics: monitor seizure control and side‑effect profile.
