Thanks for posting your query on XXXXXXX

Claritin is loratadine, an antiallergic and clarithromycin is an antibiotic.

Clarithromycin can inhibit Cytochrome P450 3A4 and should not be given with non-sedating antihistamines like loratadine. Thus clarithromycin increases the effects of loratadine.

Convulsions are a known, less common but serious side-effect of loratidine. If we give clarithromycin along with loratadine, there are increased chances of getting convulsions due to increased concentration of loratadine in blood.

Hope this answers your query. Let me know if I can assist you further.

if it is given and unknowingly patient is diagnosed for epilepsy/Hashimoto Encephilopathy. Drugged with steroids and anticonvulsants. How to overcome and negate the effects of the medication the patient had developed such as involuntary movement of the leg ( similar to myclonic jerks). Is there an antidote to cure such a condition. Otherwise the patient has no known history of epilepsy.

Brief Answer:
We need to correlate to diagnose

Detailed Answer:
Hi again,

I will explain a little so that we can make better sense out of the situation.

Usually whenever seizures happen due to the medicine loratadine, these develop within 8 hours of taking it and go away soon after discontinuing the medicine. May take a little longer due to clarithromycin for seizures to go away, but still should not take more than a day or two. If the intake of medicine was recent, then we can flush it out sooner by drinking lots of pure water and other fluids. Such episodes should be prevented in future. The type of seizures that have been reported are Grand mal seizues. Antidote is not available and moreover it is not required. The seizures are controlled with anti-epileptic and are usually not needed beyond the episode.

Hashimoto encephalopathy has both neurologic and psychiatric symptoms. It responds drastically to steroids.

PKD has many causes including genetic and the patient usually learns to control the abnormal movements of the leg by immediately repeating the movement.
