Side Effects of Primidone

Primidone, frequently sold under the brand name Mysoline, is used in the treatment and prevention of seizures. The use of this medication may cause a variety of mild to severe side effects based on the particular individual and other variables.

  1. Identification

    • Primidone is a prescription drug classified as a anticonvulsant. It works by affecting the nerve pulses in the nervous system. By doing so, Primidone lowers the response of the nerves so that sudden seizures can be both prevented and treated. Other uses for Primidone may be discussed with your doctor.

    Common Side Effects

    • Primidone can lead to the following common side effects: nausea, upset stomach, dizziness and drowsiness, vomiting, loss of coordination and lightheadedness. Though common and less serious than other side effects, the persistent occurrence of any from the above list may signal a serious condition. Discuss all chronic side effects with your doctor.

    Serious Side Effects

    • According to Drugs.com, Primidone use may cause a number of severe side effects, including double vision, fever, severe measles-like rash, extreme mood changes, worsening seizures, extreme tiredness and weakness, and decreased sexual ability. In addition, Primidone may trigger a severe allergic reaction recognized by a skin rash and swelling of the face. Seek immediate medical attention in any of the above cases.

    Considerations

    • Primidone may be taken with or without food, but if upset stomach occurs, taking the medication with food is recommended. Primidone is often taken two to four times daily. In the case of a missed dose, never take a double dose to compensate. Always follow your prescription to its exact specifications.

    Warnings

    • An ID card or tag explaining your seizure disorder should be available at all times to help in the case of an emergency. Take caution while driving, as Primidone can cause drowsiness and lightheadedness. Hormonal birth control medication should not be used with Primidone. This drug can cause harm to an unborn fetus or to a breast-feeding child.
