Side Effects

Common Side Effects:

• Drowsiness, fatigue, dizziness, headache
• Loss of appetite, weight loss (anorexia)
• Nausea, diarrhea, constipation
• Agitation, irritability, confusion, difficulty concentrating, poor memory
• Skin rash
• Poor muscle coordination, altered walking, impaired coordination, uncontrolled movements
• Decreased blood levels of bicarbonate

Serious Side Effects:

• Severe allergic reactions (e.g., difficulty breathing, swelling of face/lips/tongue, severe skin rash).
• Signs of overheating (e.g., high body temperature, little or no sweating, rapid heartbeat/breathing, muscle cramps, confusion).
• Mood changes, worsening depression, or suicidal thoughts.
• Kidney stones (manifesting as sudden pain in the back or stomach, pain on urinating, or blood in urine).
• Vision problems, including eye pain, blurred vision, or potential permanent vision loss.
• Severe skin reactions such as Stevens-Johnson syndrome and toxic epidermal necrolysis.

Precautions

• Allergy: Contraindicated in individuals with hypersensitivity to Zonisamide, other sulfonamide medicines, or any capsule ingredients.
• Pregnancy: ZONISEP is a pregnancy category C medicine. It should be used during pregnancy only if the potential benefit outweighs the risk, as it may lead to serious birth defects. Women of childbearing potential should use effective contraception.
• Breastfeeding: Zonisamide is excreted in human milk and is considered unsafe during breastfeeding due to potential harm to the infant. Consultation with a doctor is necessary.
• Alcohol: Avoid alcohol consumption as it can intensify dizziness and sleepiness, and may increase the risk of seizures.
• Liver and Kidney Impairment: Use with caution in patients with liver or kidney problems, and dose adjustments may be necessary. Regular monitoring of kidney function is advised, and adequate hydration is crucial to reduce the risk of kidney stones.
• Driving and Operating Machinery: Due to potential drowsiness and dizziness, patients should exercise caution when driving or operating machinery until they know how the medicine affects them.
• Children: Not recommended for children under 6 years of age. Caution is advised in children under 12 or those who are underweight, as they may be at higher risk for certain issues like decreased sweating, heat stroke, pneumonia, and liver problems.
• Elderly Patients: Elderly individuals may be more susceptible to side effects like drowsiness, dizziness, and confusion, necessitating careful dose adjustment.
• Other: Patients should stay well-hydrated, especially in warm weather, as Zonisep can reduce sweating and lead to overheating. Monitoring for changes in mood, depression, or suicidal thoughts is important. Inform your doctor about any history of glaucoma, high ammonia levels, osteoporosis, or low blood bicarbonate levels.

Storage

• Store ZONISEP 100MG CAPSULE in a cool and dry place.
• Keep it below 30°C and away from direct sunlight and moisture.
• Keep out of sight and reach of children.
• Ensure the container is tightly closed.

What is ZONISEP 100MG CAPSULE used for?

ZONISEP 100MG CAPSULE, containing Zonisamide, is an anti-epileptic medication primarily used to treat epilepsy, specifically partial seizures (also known as focal seizures). It can be used as a standalone therapy in adults or in combination with other anti-epileptic medicines for adults and children aged 6 years and older.

How does ZONISEP 100MG CAPSULE work?

ZONISEP (Zonisamide) works by stabilizing the abnormal electrical activity in the brain that causes seizures. It achieves this by blocking voltage-sensitive sodium and T-type calcium channels in nerve cells, which reduces excessive nerve impulses. Additionally, it may enhance the release of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter, and is a weak carbonic anhydrase inhibitor, both contributing to its anticonvulsant effects.

What is the usual dosage for ZONISEP 100MG CAPSULE?

The dosage of ZONISEP 100MG CAPSULE is determined by your doctor based on your condition and how you respond to the medicine. For adults, as an add-on therapy, the initial dose is typically 100 mg once daily. This dose may be gradually increased, for example, to 200 mg daily after two weeks, and further to 300-400 mg daily, with at least two weeks between dose adjustments. It is usually taken once or twice a day, with or without food, and should be swallowed whole with a glass of water.

What are the possible side effects of ZONISEP 100MG CAPSULE?

Common side effects of ZONISEP include dizziness, drowsiness, headache, nausea, loss of appetite, irritability, confusion, and depression. Other possible side effects include impaired concentration, altered walking, impaired coordination, and uncontrolled movements. Serious, though less common, side effects can include severe skin reactions, vision problems (such as eye pain, redness, or changes in vision, potentially leading to permanent vision loss), kidney stones, decreased sweating leading to overheating, mood swings, and suicidal thoughts or behavior.

Is ZONISEP 100MG CAPSULE safe during pregnancy or breastfeeding?

During Pregnancy: ZONISEP is generally not recommended during pregnancy unless your doctor determines it is absolutely necessary. Limited evidence suggests it may harm an unborn baby. Women of childbearing potential are advised to use effective contraception during treatment and for one month after discontinuing the medicine.

During Breastfeeding: ZONISEP is not recommended for use by breastfeeding mothers, as the active ingredient, Zonisamide, passes into breast milk and could lead to side effects in the breastfed baby.

Can ZONISEP 100MG CAPSULE be taken with other medications?

ZONISEP can interact with other medications. For example, taking it with carbonic anhydrase inhibitors may increase the risk of metabolic acidosis. Other anti-epileptic drugs such as carbamazepine, phenytoin, and phenobarbital can increase the clearance of Zonisep, which might require a dosage adjustment of Zonisep. Zonisep may also reduce the effectiveness of oral contraceptives. It is crucial to inform your doctor about all other medications you are currently taking to avoid potential interactions.

What precautions should be taken while taking ZONISEP 100MG CAPSULE?

Several precautions should be observed while taking ZONISEP:

• Alcohol: Avoid consuming alcohol, as it can increase dizziness and sleepiness and may worsen seizures.
• Driving/Operating Machinery: Do not drive or operate heavy machinery until you understand how the medication affects you, as it can cause drowsiness and dizziness.
• Hydration & Overheating: Drink plenty of water to reduce the risk of kidney stones and heat stroke, especially in warm weather or during exercise, as Zonisep can decrease sweating.
• Medical Conditions: Inform your doctor if you have kidney or liver problems, a history of kidney stones, depression, suicidal thoughts, or if you are underweight.
• Sudden Discontinuation: Do not stop taking ZONISEP suddenly without consulting your doctor, as this can worsen seizures.
• Monitoring: Your doctor may monitor your weight, kidney function, and blood bicarbonate levels regularly. Also, be vigilant for any changes in mood or behavior, new or worsening depression, or suicidal thoughts. Immediately report any eye pain, redness, or vision changes to your doctor.
• Children and Elderly: ZONISEP is not recommended for children under 6 years of age. Children under 12 may be at increased risk of certain issues like decreased sweating and heat stroke. Elderly patients may be more sensitive to the side effects.

What happens if a dose of ZONISEP 100MG CAPSULE is missed?

If you miss a dose of ZONISEP, take it as soon as you remember. However, if it is almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to compensate for a missed one, as this could increase the risk of side effects or worsen seizures.

How should ZONISEP 100MG CAPSULE be stored?

ZONISEP 100MG CAPSULE should be stored in a cool and dry place, away from direct sunlight. It should be kept at room temperature, ideally between 10ºC to 25ºC or below 30ºC. Keep the medicine in a tightly closed container and out of the sight and reach of children.
