In the Philippines, senior citizens can avail discounts on prescribed medicines under the Expanded Senior Citizens Act (RA 9994). Typically, this includes a 20% discount on the retail price and exemption from the value-added tax (VAT) on qualified medicines. To access these benefits, seniors need to present their senior citizen ID at pharmacies. It's advisable to check with local pharmacies and the official Department of Social Welfare and Development (DSWD) website for specific details and eligibility requirements.
