If you have been prescribed Klonopin, you should take the time to educate yourself about the possible side effects, withdrawal symptoms, and symptoms of overdose. Rivotril is another brand name of clonazepam used in some other countries.
Uses
Klonopin is in a class of medications known as benzodiazepines. It comes both in a pill form and as a dissolvable tablet. It has been approved by the Food and Drug Administration to treat certain types of seizure disorders in adults and children and panic disorder with or without agoraphobia (fear of open spaces). Klonopin can also be used to treat alcohol withdrawal, sleeping difficulties, and anxiety related to bipolar disorder or other mood disorders.
Side Effects
When combined with opioid drugs or alcohol, benzodiazepines can cause serious side effects. Some side effects may develop when first stating Klonopin, many of which will resolve on their own as your body begins to adjust to treatment. You should call your doctor if any of these common side effects are severe or fail to go away:
Changes in sex drive or sexual functionDifficulty thinking or rememberingDizzinessDrowsinessProblems with coordinationUnsteadinessVision changes
Rarely, Klonopin can cause the following side effects:
AnemiaChest congestionCoated tongueConstipationDry mouthHair lossHeart palpitationsHirsutism (excessive hair growth)Lymphadenopathy (swollen lymph nodes)Runny noseShortness of breathSkin rashSore gums
If you experience these or any other unusual side effects, call your doctor right away. This can potentially be symptoms of a severe, all-body allergic reaction known as anaphylaxis. If left untreated, anaphylaxis can lead to respiratory distress, seizure, coma, respiratory or cardiac failure, and death.

Withdrawal Symptoms
You should never suddenly stop taking Klonopin without your doctor’s approval, particularly if you’ve been on treatment for some time or are using it to control seizures. If you do need to stop, your doctor will generally wean you off treatment. Some of the more common withdrawal symptoms include:
IrritabilityNervousnessTrouble sleeping
These symptoms are relatively manageable and will eventually resolve as the daily dosage is decreased. Sometimes withdrawal symptoms can last for a long time or longer than expected, however.
