Procaine HCl, while generally considered safe when administered by healthcare professionals for its intended purpose as a local anesthetic, can present side effects and interact with other medications. Understanding these aspects is crucial for safe and effective use. The procaine HCl side effects are typically dose-dependent and can manifest in various ways, affecting both the central nervous system (CNS) and cardiovascular system.

Common CNS side effects include dizziness, nervousness, tremors, and, in rare cases of high dosage or rapid injection, seizures. Cardiovascular effects can include bradycardia (slow heart rate) and hypotension (low blood pressure). Allergic reactions, though uncommon, are a significant consideration. These are often attributed to the metabolite PABA rather than procaine itself. Symptoms can range from skin rashes and itching to more severe anaphylactic reactions in highly sensitive individuals. Patients with pseudocholinesterase deficiency, a genetic condition, may experience prolonged effects and increased toxicity from procaine HCl due to impaired metabolism.

When considering procaine HCl drug interactions, several classes of medications warrant attention. For instance, procaine HCl can potentiate the effects of neuromuscular blocking agents, potentially leading to prolonged muscle paralysis. It may also interact with sulfonamide antibiotics, as the PABA metabolite of procaine can interfere with the antibacterial action of sulfonamides. The use of procaine HCl concurrently with monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants is generally not recommended due to potential hypertensive crises.

Furthermore, the co-administration of procaine HCl with other local anesthetics should be done with caution, as it can increase the risk of systemic toxicity. Drugs that affect cardiac rhythm or blood pressure may also interact with procaine HCl, necessitating careful clinical assessment. It is imperative for patients to disclose all medications, including over-the-counter drugs and herbal supplements, to their healthcare provider before receiving procaine HCl injections.
