Summary
Ammonium chloride acidifies urine, which increases renal excretion of methamphetamine and lowers its plasma levels. This can reduce therapeutic effect and shorten duration of action.
What this interaction means in plain words
Ammonium chloride and Methamphetamine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Urinary acidification increases ionization of methamphetamine and reduces tubular reabsorption, enhancing renal elimination.
What to do
Assess clinical response if urinary acidifiers are started or stopped, and adjust methamphetamine dose as needed. Avoid unnecessary acidifying agents.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
