Ciplactin, the brand name for cyproheptadine hydrochloride, is a prescription medication indicated to alleviate symptoms associated with nasal allergies and the common cold. In the United States, this medication is marketed under the brand name Periactin. Ciplactin is a type of antihistamine and works by inhibiting histamine, an allergy-inducing substance within the body. Patients prescribed Ciplactin should discuss potential side effects with a doctor before beginning treatment.
Treatment with Ciplactin can cause mild to moderate sinus irritation in certain patients. This medication can dry out the nasal passageways and throat, which can cause sensations of dryness to develop within the nose, mouth or throat. Sinus irritation can contribute to side effects of sneezing, increased thirst or sore throat in certain patients.
Drowsiness or Weakness
After taking a dose of Ciplactin, patients may experience unusual drowsiness or weakness as side effects of treatment. Tiredness or muscle weakness can interfere with a patient's ability to remain alert and productive while at work or school. Patients who experience these side effects in conjunction with confusion or hallucinations should contact a doctor immediately.
Headache or Dizziness
Patients receiving treatment with Ciplactin can experience headache or dizziness as side effects, explains Medline Plus, a health information resource provided by the National Institutes of Health. Painful headache symptoms can become uncomfortable and can develop within any region of the head. Sensations of dizziness may be accompanied by confusion or difficulty walking normally. A patient who develops vision difficulties, such as blurred or cloudy vision, in conjunction with these side effects should seek immediate medical care from a physician.
Insomnia or Restlessness
During treatment with this medication, certain patients--particularly children--can become unusually restless, nervous or hyperactive. These side effects of Ciplactin can make it difficult for affected patients to fall asleep or stay asleep throughout the night--a condition referred to as insomnia. Patients who do not receive adequate amounts of sleep during Ciplactin treatment may feel abnormally tired during the day.
After taking a dose of Ciplactin, patients can develop an upset stomach as a side effect of treatment. Symptoms of stomach upset can include nausea, vomiting or appetite changes. Certain patients may also develop bowel movement changes, such as constipation or diarrhea. These side effects can become uncomfortable and may contribute to sensations of stomach bloating, cramping or discomfort.
Abnormal Skin Sensations
Treatment with Ciplactin can cause patients to develop unusual skin sensations as a side effect, explains Drugs.com, a peer-reviewed drug information website for consumers. Affected patients may experience a numb or tingly feeling within the skin, which can become uncomfortable or irritating. Patients who develop unusual skin bleeding or bruising in addition to these abnormal sensations should contact a medical care provider as soon as possible.
