What is Clamist 0.5 mg Syrup 60 mL?

Clamist 0.5 mg Syrup 60 mL is a prescription allergy medicine that contains clemastine, a first-generation antihistamine. Each 60 mL bottle of Clamist 0.5 mg Syrup contains clemastine 0.5 mg in syrup form, which is taken by mouth. It is used to help relieve symptoms of allergic conditions such as sneezing, runny nose, itchy or watery eyes, and itching. Because clemastine can also cause drowsiness, this strength may be chosen when a clinician wants allergy relief in an easy-to-swallow liquid form.

How it works: Clemastine blocks histamine, a natural chemical your body releases during allergic reactions. In syrup form, Clamist 0.5 mg Syrup 60 mL is swallowed and absorbed through the digestive tract to help reduce allergy symptoms.

Why choose Clamist 0.5 mg Syrup 60 mL?

Clamist 0.5 mg Syrup 60 mL is a lower-dose liquid option that may suit people who need flexible dosing or have trouble swallowing tablets. Compared with higher-dose antihistamine products, this syrup may feel milder for some patients, but it can still cause sleepiness and should be used only as directed by a doctor. The syrup form is often chosen when a patient needs a measured oral dose in a form that is easier to take than solid dosage forms.

Uses of Clamist 0.5 mg Syrup 60 mL

  • Seasonal allergic rhinitis
  • Perennial allergy symptoms
  • Sneezing and runny nose
  • Itchy or watery eyes
  • Itching from allergies

How to take Clamist 0.5 mg Syrup 60 mL

  • Take Clamist 0.5 mg Syrup 60 mL by mouth exactly as prescribed.
  • Measure the dose carefully with an oral syringe or marked measuring spoon, not a kitchen spoon.
  • Shake the bottle well before each dose if the label or pharmacist instructs you to do so.
  • If it makes you sleepy, take it at a time your doctor recommends, often in the evening.
  • Avoid driving or using machinery until you know how this syrup affects you.
  • Do not take extra doses to make up for missed doses unless your prescriber tells you to.

Clamist 0.5 mg Syrup 60 mL dosage

Clamist 0.5 mg Syrup 60 mL provides 0.5 mg of clemastine in the bottle strength named on the label, and the exact amount per dose depends on the prescriber’s instructions and the measuring device used. Adults and children may take it once or several times daily depending on the condition being treated, but the maximum daily amount must be set by a doctor because clemastine can cause significant drowsiness and other anticholinergic effects. Always follow the prescribed schedule for this 0.5 mg syrup and do not increase the dose on your own.

Do not change your dose or stop the medicine without speaking to your doctor.
