Warnings and precautions

Consult your doctor or pharmacist before starting to take this medication:

• If you have a severe respiratory disease.
• If you have porphyria (a rare disorder, usually inherited, in which a large amount of porphyrin is eliminated in feces and urine)
• If you have a disease in which there is an abnormal increase in the activity of the thyroid gland (hyperthyroidism), high intraocular pressure, heart disease, or high blood pressure.
• If you are using a medication that produces ototoxicity, as the symptoms of these effects may be masked, such as tinnitus, dizziness, or vertigo.
• If you have any kidney disease or disorder

Antihistamines can decrease alertness; on the other hand, they can produce excitement, especially in small children.

Rarely, long-term treatment with antihistamines can cause alterations in blood cell counts.

Antihistamine treatment can mask the toxic effects of medications that produce ototoxicity.

Children and adolescents

This medication should not be used in newborns or premature babies (see "Do not take Periactin").

This medication is not recommended for children under 2 years of age because its efficacy and safety have not been established in this population.

Given the high sensitivity of children to antihistamines, the dose of ciproheptadina should be established with special caution in this group.

Other medications and Periactin

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

Inform your doctor if you are taking:

• Monoamine oxidase inhibitors (MAOIs), such as, for example, moclobemide (used to treat depression) or selegiline, rasagiline (used to treat Parkinson's disease). These medications should not be taken at the same time as Periactin (see section 2 "Do not take Periactin").
• Medications that induce sleep and medications that reduce the activity of the central nervous system (hypnotics, sedatives, tranquilizers, anxiolytics). This medication may increase their effects.

• Selective serotonin reuptake inhibitors, such as, for example, fluoxetine, paroxetine, sertraline, citalopram, escitalopram (medications used to treat depression), as Periactin may cause a possible recurrence of depression and associated symptoms.
