An allergic reaction to sulphate drugs may also include a rash on the skin, headaches, wheezing or trouble breathing, and asthma attacks in people with asthma, explains Healthline. In rare cases, individuals may experience reactions such as swollen lymph nodes, fever, skin eruptions and drug-induced arthritis approximately 10 days after ingesting sulfa drugs. These symptoms are not common.

Many antibiotic drugs contain sulphates, according to Healthline. Drugs used to treat Crohn's disease, rheumatoid arthritis, dermatitis and certain types of pneumonia should be avoided by individuals with a known allergy or sensitivity to sulfa. Some medications that have only traces of sulphates, such as diabetes medicine, non-steroidal anti-inflammatory drugs, migraine medication and certain diuretics, may be safe to take. Patients should consult with a physician prior to taking any type of medication that has traces of sulphates to determine if an allergic reaction is possible.

Sulfites are another form of chemicals that often cause allergic reactions, Healthline advises. They are commonly found in drug treatments, alcoholic beverages, condiments and processed food. People with a sulfite allergy should avoid consuming wine that naturally produces sulfites during fermentation.
