Nervous system

• Very common (10% or more): Headache (up to 26%)
• Common (1% to 10%): Sinus headache
• Rare (0.01% to 0.1%): Bulging fontanels (in infants), benign intracranial hypertension (pseudotumor cerebri [symptoms include blurred vision, scotomata, diplopia]), tinnitus
• Frequency not reported: Hypoesthesia, increased intracranial pressure, paresthesia, somnolence, stupor, taste loss, drowsiness, amnesia, paresthesias of body areas exposed to sunlight, phrenic nerve paralysis after sclerotherapy
• Postmarketing reports: Pseudotumor cerebri, headache, dizziness^[Ref]

Benign intracranial hypertension resulting in permanent loss of vision has been reported.

A 70-year-old female patient with no significant medical history suddenly developed a severe headache followed by vomiting about 15 minutes after the initial dose of this drug. The patient also experienced memory dysfunction; she could not remember the events of the afternoon prior to the dose of this drug and could not retain the information after she was reminded. The incident lasted about 30 minutes and she was transported to the hospital for further evaluation. No further cause, such as intoxication or trauma, could be elicited. Once at the hospital, the patient was able to remember the events of the afternoon and could retain new information, but amnesia regarding the events of the 30 minutes following the onset of the headache persisted. The patient's laboratory results, computerized tomography scan, MRI scan, cerebrospinal fluid, and electroencephalogram showed no pathology. When the patient was discharged 2 days later, the amnesia for the 30 minutes continued. After elimination of other symptomatic causes, the amnesia was concluded to be due to this drug because of the close relation of the dose and the onset of symptoms.^[Ref]

Numerous cases of esophageal ulceration have been reported. In most cases, the patients had taken their medication at bedtime, usually without enough liquid. Patients often presented with severe retrosternal pain and difficulty swallowing. Ulcerations generally resolved within a week after discontinuing the drug. In 1 case report, severe hiccups of 4-day duration associated with esophagitis followed the first dose of this drug.

In a double-blinded study, this drug was found to be more phototoxic than minocycline and demeclocycline. Paresthesias of the body areas exposed to sunlight may be early signs of sunburn reactions.

A case report of a possible photoallergic reaction described scaly erythema and vesicles on the face and neck associated with administration of this drug. Upon rechallenge, a flare with erythema, itching, and burning occurred in the same area.

Another case report was documented in Australian troops treated with 100 mg daily for malaria prophylaxis while on deployment in East Timor, a group of islands within the Malaysian archipelago located close to the equator. Of the 135 troops, 22 exhibited phototoxic reactions to low doses of this drug that resembled severe sunburn with erythematous plaques on the sun-exposed areas. The troops used a sunscreen containing oxybenzone.

An 11-year-old boy treated with this drug for brucellosis was evaluated for painless brown nail discoloration. This drug was initiated for brucellosis but stopped when the boy developed photosensitivity, but 15 days after the initiation of therapy brown nail discoloration developed. Other than the brown discoloration, the boy's physical condition was normal and the discoloration disappeared within 1 month.^[Ref]
