Capron DM

Dextromethorphan is a cough suppressant and pyrilamine is an antihistamine.

Capron DM is a combination medicine used to treat cough, runny nose, sneezing, itching, and watery eyes caused by allergies, the common cold, or the flu.

Capron DM will not treat a cough that is caused by smoking, asthma, or emphysema.

Capron DM may also be used for purposes not listed in this medication guide.

Use exactly as directed on the label, or as prescribed by your doctor. Cold or cough medicine is only for short-term use until your symptoms go away.

Always follow the instructions on the medicine label when giving cough or cold medicine to a child. Do not use the medicine just to make a child sleepy. Misusing cough or cold medicines in very young children can lead to death.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Call your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever along with a headache, cough, or skin rash.

Store at room temperature away from moisture and heat.

Do not use Capron DM if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, rasagiline, selegiline, or tranylcypromine.

Do not use this medicine only to make a child sleepy. Death can occur from the misuse of cough or cold medicines in very young children.
