The Medicines Control Authority of Zimbabwe (MCAZ) has warned of potential health risks associated with combining prescribed medicines and herbal remedies, urging patients to seek professional advice before mixing treatments.
In a statement issued on Monday, November 2, the regulator cautioned that adverse reactions may occur when patients start new medication, change dosages or combine conventional medicines with herbal remedies, certain foods or other drugs.
The warning raises concerns about public awareness of medicine interactions, particularly among patients who use traditional and conventional treatments simultaneously without informing healthcare professionals.
Although herbal remedies are widely used in Zimbabwe, their natural origins do not necessarily guarantee safety. Certain herbal substances can interact with prescribed medicines, potentially affecting their effectiveness or increasing the risk of unwanted reactions.
MCAZ also warned that some side effects develop gradually, while others remain undetected until medical examinations reveal abnormalities.
The authority encouraged patients to read medicine information leaflets, consult healthcare professionals and report suspected adverse reactions, even when they cannot establish a direct connection between their symptoms and medication.
MCAZ Director-General Richard Rukwata said public participation was critical to monitoring medicine safety.
“Reports from the public and healthcare professionals have a vital role in helping us monitor the safety of medicines. Every report adds to our understanding about patient safety and can help protect others from future harm,” Rukwata said.
“Reporting suspected side effects may seem like a small action, but it helps to make medicines safer for everyone. If you suspect a side effect, don’t ignore it — report it!”
The warning comes as Zimbabwe joins the 2026 global #MedSafetyWeek campaign, running from November 2 to 8, involving 140 organisations across 130 countries.
Zimbabwe has participated in the World Health Organization’s International Drug Monitoring Programme since 1998, with MCAZ serving as the country’s National Pharmacovigilance Centre.
The regulator monitors medicine safety through laboratory testing, regulatory inspections and post-market surveillance.
Zimbabweans can report suspected adverse reactions through healthcare professionals, MCAZ’s online reporting platforms, WhatsApp or designated toll-free numbers.
