I. Side Effects of Glutathione Tablets
1. Gastrointestinal Side Effects
(1) Glutathione Tablets may cause a series of gastrointestinal discomforts, including anorexia, nausea, vomiting, stomach pain, etc.
(2) These reactions have a low incidence. Gastrointestinal symptoms are usually mild and transient, mostly occurring at the initial stage of treatment, and may gradually resolve as the body adapts.
(3) Individual patients with sensitive constitutions may have slightly more obvious reactions, but generally do not affect continued treatment.
2. Allergic Reactions
(1) A small number of patients may experience allergic reactions, mainly manifested as skin symptoms such as rash.
(2) The rash may present as local or generalized erythema, papules, with or without pruritus.
(3) Severe allergic reactions are extremely rare. Patients with a history of drug allergy should pay special attention to physical changes after administration.
3. Characteristics of Side Effects
(1) Glutathione is a naturally occurring substance in the human body, and exogenous supplementation is well-tolerated.
(2) The incidence of side effects is low and symptoms are mild; most patients can recover spontaneously without special treatment.
(3) Compared with conventional chemical drugs, it has a narrower side effect profile, and severe adverse reactions are rare.
(4) However, individual differences exist objectively, and any discomfort deserves attention.
4. Symptoms Requiring Attention
(1) Although severe side effects are rare, immediate medical attention should be sought in the following situations: extensive or progressively worsening rash; severe nausea and vomiting leading to inability to eat; persistent unrelieved stomach pain; any unexpected severe discomfort.
(2) Professional evaluation is also required if original symptoms worsen or new symptoms occur.
II. Methods to Alleviate Side Effects of Glutathione Tablets
1. Management of Gastrointestinal Discomfort
1.1 Management of Anorexia
(1) If loss of appetite occurs, try adjusting the administration time to 30–60 minutes after meals to reduce direct gastrointestinal irritation.
(2) Choose light and easily digestible foods such as porridge, noodles, steamed eggs, etc., and avoid greasy and spicy foods that may aggravate discomfort.
(3) Eat small and frequent meals to ensure basic nutritional intake.
1.2 Relief of Nausea and Vomiting
(1) When nausea occurs, deep breathing, smelling fresh lemon peel or peppermint may help relieve the sensation.
(2) If vomiting is obvious, pay attention to replenishing water and electrolytes to prevent dehydration.
(3) Do not eat immediately after vomiting; drink a small amount of water after the stomach stabilizes.
(4) If vomiting occurs within 30 minutes after administration, consult a doctor about whether a supplementary dose is needed.
1.3 Management of Stomach Pain
(1) For mild to moderate stomach pain, local hot compress and resting in a comfortable position may be tried.
(2) Avoid taking other analgesics to prevent masking the condition or drug interactions.
(3) Seek medical attention promptly if stomach pain persists or worsens.
2. Care for Allergic Reactions
2.1 Management of Rash
(1) Discontinue medication immediately if a rash appears and consult a doctor.
(2) Avoid scratching the rash area to prevent skin damage and infection.
(3) Wear loose, soft cotton clothing to reduce friction.
(4) Keep the skin clean and dry; clean with warm water and pat dry gently.
2.2 Relief of Pruritus

2.3 Management of Severe Allergic Reactions

(2) Although severe allergy to glutathione is rare, emergency treatment is necessary once it occurs.
3. Optimization of Administration Method
3.1 Correct Administration

3.2 Selection of Administration Time
(1) The administration time can be adjusted according to personal reactions.
(2) If discomfort occurs on an empty stomach, switch to after meals; for multiple daily doses, distribute the dosage evenly to avoid excessively large single doses.
