A patient with a spasticity problem would discontinue dantrolene after no relief for how long?

• A. 2 weeks
• B. 2 months
• C. 6 months
• D. 1 year

Answer: (B)

When evaluating a drug for spasticity, you give it a reasonable trial period for an effect to become evident, then reassess. Dantrolene works by reducing calcium release in skeletal muscle, which can take several weeks to months to translate into noticeable tone changes with oral dosing. If there’s no appreciable relief after about two months of consistent therapy, continuing the medication is unlikely to provide benefit and only increases exposure to risks such as liver toxicity and fatigue. At that point, it makes sense to discontinue and consider alternatives or additional therapies.
