Is Tonopan dangerous?
Every medicine has its own side effects and these side effects are unlikely to happen if taken as directed. Usually, the benefits of the medicine are greater than the risk of side effects. Tonopan can rarely cause serious side-effects which can be dangerous, like anaphylaxis (red and lumpy skin rash, difficulty breathing, swelling of face, mouth, lips or eyelids), clot in another part of the body or eye problems. Do consult your doctor before you start this medication and follow the instructions strictly as given.
