What Is Cyproheptadine?

Cyproheptadine (Periactin) is a prescription medication used to manage allergic conditions including allergic rhinitis, urticaria (hives), and other hypersensitivity reactions. It works by blocking histamine H1 receptors and also has antiserotonergic properties, reducing the effects of histamine and serotonin that drive allergy symptoms. With the right dose and ongoing monitoring, cyproheptadine can provide effective relief from itching, sneezing, runny nose, and skin reactions.

Is Online Cyproheptadine Treatment Right for You?

Doctronic can help you refill cyproheptadine (Periactin) if you have an established diagnosis of allergic rhinitis, chronic urticaria, or another condition for which your doctor has previously prescribed this medication. You must be a current user of cyproheptadine with a known, stable treatment history.

Because cyproheptadine acts on the central nervous system through its antihistamine and antiserotonergic effects, our physicians will review your history of sedation tolerance, any concurrent medications, and relevant conditions such as asthma, glaucoma, or enlarged prostate before approving a refill.

Frequently asked questions

Cyproheptadine is primarily prescribed for allergic conditions such as allergic rhinitis (hay fever), chronic urticaria (hives), and other hypersensitivity reactions. It works by blocking histamine H1 receptors, which reduces itching, sneezing, runny nose, and skin redness or swelling caused by allergic responses.

Cyproheptadine is a first-generation antihistamine, meaning it crosses the blood-brain barrier more readily than second-generation antihistamines. This gives it a stronger sedative effect, which can be beneficial in some contexts but may impair alertness. It also has antiserotonergic activity that newer antihistamines lack.

For adults, cyproheptadine is commonly prescribed at 4 mg three or four times daily, with a maximum dose of 0.5 mg per kg of body weight per day. Your prescribing physician determines the dose that is right for your specific condition and health history.

Yes. Sedation is one of the most common side effects of cyproheptadine due to its first-generation antihistamine properties. Patients are typically advised to avoid driving or operating heavy machinery until they know how the medication affects them. Taking the medication at bedtime can help manage this side effect.

Cyproheptadine should be used with caution in patients with narrow-angle glaucoma, urinary retention, benign prostatic hyperplasia, asthma, or peptic ulcer disease. It should not be taken by patients who are already using monoamine oxidase inhibitors (MAOIs). Your physician will review your health history before approving a refill.

The most common side effects include drowsiness, dry mouth, dizziness, blurred vision, and increased appetite. Increased appetite and weight gain are notable effects, which is why cyproheptadine is sometimes used off-label in certain clinical contexts. Tell your doctor if any side effects become bothersome or severe.

Doctronic uses an AI-powered evaluation to gather your symptoms and medical history, which is then reviewed by a licensed physician. The physician determines whether a treatment plan or prescription refill is appropriate and issues one if it is safe and clinically suitable for you.
