Capsules often contain gelatin; in Muslim countries, locally made capsules may use halal gelatin, but in Western countries they are more likely non‑halal. Where possible, choose tablet, caplet, or syrup alternatives and ask the pharmacy for options. Some injections and hormone or enzyme preparations (e.g., pancreatic enzymes, enoxaparin) may contain porcine derivatives and may have no alternatives. In such cases, consult knowledgeable scholars and medical professionals for guidance before deciding.
