Doxycycline can make oral contraceptive pills less effective.
Doxycycline is a tetracycline antibiotic that fights infection-causing bacteria in the body. It is used for many different types of infections, including sinus infections or sinus infections in severe cases. While taking doxycycline for a sinus infection can help clear the infection faster, the drug can cause side effects and interact with other medications and supplements.
Side effects of doxycycline can include nausea and vomiting.
In most countries, doxycycline requires a prescription. When using doxycycline for a sinus infection, patients typically take 100 to 200 mg daily for seven to 10 days to help fight the infection. It is important that patients take all doses exactly as recommended, even if they feel better before taking the full course of medication. This helps to prevent the infection from recurring. Both children over eight and adults can take doxycycline, although a child’s dose is typically lower than an adult’s and is based on weight.
People who suffer from severe or chronic sinus infections may benefit from taking an antibiotic such as doxycycline.
Although most sinus infections go away on their own, people with severe or chronic infections may need an antibiotic to get better. Doxycycline is normally given only to patients with sinusitis who have had symptoms for several days with worsening or no improvement in symptoms. Some people fear that overuse of antibiotics will lead to drug-resistant bacteria and infections. This is a big part of why doxycycline requires a prescription from a doctor who has examined the patient and determined that an antibiotic is needed in many countries.
In addition to prescribing antibiotics, the doctor may order a CT scan for a patient suffering from recurrent sinusitis.
Like all medicines, doxycycline can cause side effects in some people. The drug is safe for most people and most side effects are not serious. Common side effects include loss of appetite, nausea, vomiting and diarrhea. Serious side effects are rare and include severe headaches, difficulty swallowing, severe headaches, and vision changes. Patients who experience these side effects should stop taking doxycycline and contact their healthcare provider to determine whether to continue taking the medication.
A person with sinus problems may seek the services of an ENT doctor.
Other medications and some vitamins and minerals can interact with antibiotics. Patients taking doxycycline for a sinus infection should inform their doctors about all supplements and medications they are currently taking to prevent a potentially dangerous interaction. Common medications that can interact with doxycycline include blood thinners, penicillin or penicillin-based antibiotics, cholesterol medications, isotretinoin, and tretinoin.
Supplements that contain calcium or iron can make doxycycline less effective. Any antacids, vitamins, or supplements that contain calcium or iron should be taken several hours before taking doxycycline to prevent them from interfering with the medication. Laxatives that contain magnesium can also decrease the effectiveness of doxycycline.
Pregnant and lactating mothers should not take doxycycline for a sinus infection as it can cause harm to the fetus or baby. Doxycycline can make oral contraceptive pills less effective. Women taking oral contraceptives should refrain from sexual intercourse or use another contraceptive method while taking doxycycline.
